This paper investigates how dimensions of sustainable service quality (SSQ) impact customer satisfaction, particularly in ISO 17025 accredited calibration laboratories in Saudi Arabia and Bahrain. The research addresses the challenge of maintaining customer satisfaction while enhancing competitive advantages through sustainable calibration services. Adopting the Stimulus-Organism-Response (S-O-R) theoretical model, this study employs a quantitative approach to test the proposed measurement model using Smart PLS 4. A pilot study with 35 respondents was conducted to validate the conceptual framework, which was based on the S-O-R theory. The pilot test confirmed the reliability of the constructs, though the sample size is limited. The findings provide preliminary support for the relationship between sustainable service quality and customer satisfaction. Future research will expand the dataset and conduct hypothesis testing to further inform practices in ISO 17025 laboratories. [ABSTRACT FROM AUTHOR]

In the context of the European Tempus project "Quality in Higher Agricultural Education in the Mediterranean (QESAMED)", Analysis and Characterization Center of Cadi Ayyad University has committed to implement a quality approach according to the ISO/IEC 17025 standard. The first objective was to accredit the testing carried out in the microbiology laboratory in response to strong demand from the food industry in the Marrakesh region. The process began with an initial assessment of the center activities to identify the main gaps from ISO/IEC 17025. The range of laboratory and standard testing to be accredited were determined and an appropriate action plan was established. After that, a staff training was programmed to improve their skills in relation to this standard and metrology concepts. Implementation of the metrology function is one of the key steps for the deployment of the continuous improvement process. This function guarantees the traceability of measurements and the reliability of microbiological testing results. Several actions have been carried out, including: (i) identification of critical quantities and associated metrological requirements, (ii) checking of the metrological consistency of equipment through the calculation of the capability coefficient. The management of equipment requires several steps, from receipt of the equipment to its decommissioning or reform: (i) identification of the equipment, (ii) creation of equipment files, (iii) performance of calibration, verification, and maintenance operations. Ultimately, the definition of a strategy ensuring metrological traceability will optimize management costs by taking into account the structural constraints linked to the organization of metrology on a national scale.

This paper reviews evidence placed before a Commission of Inquiry (CoI) established by the State of Queensland, Australia, to consider the quality and reliability of DNA evidence. It also assesses whether the criticism levied in that report, of ISO/IEC 17025 being insufficient to assure the quality and reliability of DNA evidence, is warranted. The main conclusion drawn is that properly applied and embraced as a means of continuous improvement, conformance with ISO/IEC 17025:2017 alone is sufficient to assure the quality and reliability of the scientific outputs from a forensic science laboratory.Furthermore, it is clear from the observations and findings of the CoI and those recorded in this paper that the forensic science laboratory in question did not conform to ISO/IEC 17025:2017. Had it done so then the risk of the quality failures that led to the CoI would at least have been reduced and perhaps even avoided.

Thermal processing equipment used in the aerospace industry must meet the requirements of the processes for which they are intended. The periodic tests performed by calibration laboratories, according to the AMS2750 specification, are intended to ensure compliance with these equipment requirements. While this specification does not explicitly state the need for uncertainty calculation, it does specify that pyrometry laboratories must have an ISO/IEC 17025 Quality System accredited by a recognized regional body which is a member of the International Laboratory Accreditation Cooperation (ILAC). Therefore, the calculation of uncertainties is necessary. This work presents a methodology for conducting temperature uniformity surveys and uncertainty assessment in these tests. This methodology has been applied to four different types of equipment to analyse, in each case, the contributions of uncertainties and to assess their potential for improvement. The objectives that laboratories should aim for include improving measurement accuracy and reducing uncertainty components in order to meet the criteria of both AMS2750 and ISO/IEC 17025.

Organizations and laboratories tend to integrate systems based on risk management. Risk management helps to optimize laboratory processes and information flow, increase valid and reliable results, and make better decisions. This paper describes the development and present trends in risk management related to standard ISO/IEC 17025. This paper focuses on risk assessment in the accredited testing laboratories using the FMEA tool. In the basic eight defined laboratory areas, risks were identified and evaluated, and methods were proposed to minimize them.

Validation of analytical methods ensures reliability and accuracy of analytical data. Accredited laboratories in accordance with the international standard ISO/IEC 17025, that is the Serbian standard SRPS ISO/IEC 17025, must fulfill and document the selection, validation, or verification of the analytical method. In the validation and verification process, it is mandatory to assess: limit of detection (LoD), limit of quantification (LoQ), linearity and measurement uncertainty.

This work describes the uncertainty calculation for the determination of chromium oxide in leather. Following the various steps for the calculation of uncertainty which includes assembling a list of sources of uncertainty, with the help of basic formula used to calculate the measure and as all parameters cause an influence on the result because of the uncertainty value associated with it then the basic cause and effect diagram is made which shows the correlation between these and indicates their effect on the uncertainty of the result.All individual sources of uncertainty are evaluated by quantification. Mass, purity, and molecular mass of potassium dichromate are calculated against the volume of sodium thiosulphate following the first step in the test method is the standardization of sodium thiosulphate with the primary standard, potassium dichromate. So the overall uncertainty value depends on the uncertainties associated with the mass, purity, and molecular mass of potassium dichromate.

Currently, testing and calibration laboratories are undergoing organizational restructuring in view of technical and regulatory requirements. To assist these laboratories, maturity models (MMs) can be used for the implementation and maintenance of management systems. The use of fuzzy logic is often found in association with the construction of MMs. Fuzzy logic helps in the construction of these models, removing subjective elements from the maturity assessment. Therefore, the objective of this study was to perform a systematic literature review (SLR) using the Methodi Ordinatio focused on MMs built with fuzzy logic that aim to evaluate the degree of maturity of testing and calibration laboratories that have implemented ISO/IEC 17025 for their quality management systems (QMSs). This analysis was performed with articles published between 2012 and 2022 in several databases using keywords such as "maturity model", "fuzzy" and "ISO 17025" and resulted in 18 articles, which made up the bibliographic portfolio. After analyzing the content of these studies, it was possible to conclude that, although no study specifically discussed this MM, the discovered articles were important for presenting ideas and suggestions for future research.

Analysis of uncertainty estimation for measurement of type and concentration of alcohol in hand sanitisers is a matter of urgency in the COVID-19 situation. FTIR spectroscopy was used to investigate hand sanitisers made in our laboratory and commercial products. An internal standard addition method was used to control the measurement quality. The absorption spectra of ethanol were found to be at 1086 and 1044 cm-1, corresponding to C-O stretching. The area under the C-O adsorptions is used to create a calibration curve, which is then used to calculate the ethanol percentage. Additional standard sample and quality control sample showed calibration curves with slopes of 0.1267 and 0.1285, respectively. The regression coefficients and residual variance of 0.0057 showed a 'best fit' with the predicted value. These parameters were used to estimate the uncertainty of six commercial products. The ethanol concentration of commercial products is measured between 71.38 and 81.54% v/v, with an estimated uncertainty of 1.14% v/v. The results showed that the ethanol content of all products differed from the label but could be used to kill bacteria and viruses. This entire process was established as a SOP for measuring alcohol concentration in hand sanitizer. [ABSTRACT FROM AUTHOR]

The third edition of the ISO/IEC 17025 standard had significant changes with respect to its predecessor version, such as the approach and structure based on the process, the thought and action based on risk and the new requirement of impartiality and confidentiality, among others, no less important. The problem was how to deal with the transition to this third version of the standard and meet all its requirements. The mission of the DECA Scientific-Technical Services Management Group (GG SCTDECA), of the CNIC, is to provide specialized Scientific-Technical Services (SCT) for the characterization of water, wastewater and solid waste, the design and technical task of technological treatment solutions, as well as material protection services. All of them are covered by a management system in accordance with NC-ISO / IEC 17025 and accredited by the National Accreditation Body of the Republic of Cuba (ONARC). The objective of the work was the strategy to be followed in the Group to comply with the new requirements of ISO/IEC 17025. The procedure, descriptive and qualitative, took into account the main changes, taking as a guide a correlation between the second and third edition of the standard, which allowed, together with a documentary review, to define what needed to be done or improved. The necessary actions were defined to comply with the new requirements of the third edition and a plan was drawn up, establishing the deadlines for compliance and those responsible for executing them. Among other actions, an Impartiality Policy was developed and records of Confidentiality Commitments were established for internal and external personnel who can influence the Laboratory's activities. A procedure was implemented to address the Risks and Opportunities, the risks to impartiality were identified, a Policy for information and communication with the interested parties was defined, the Process Map and the Process Files were improved, the Profiles were adapted staff competence and training seminars were held.

Since December 2019, the worldwide public health has been threatened by a severe acute respiratory syndrome caused by Coronavirus-2. From the beginning, a turning point has been the identification of new cases of infection, in order to minimize the virus spreading among the population. For this reason, it was necessary introducing a panel of tests able to identify positive cases, which became crucial for all countries. As a Regional Reference Centre, the CRQ Laboratory (Regional Laboratory for the Quality Control) developed and conducted an External Quality Assessment (EQA) panel of assay, so as to evaluate the quality of real-time reverse transcription polymerase chain reaction (PCR), which were used by 62 Sicilian laboratories, previously authorized to issue certificates for the COVID-19 diagnosis, on behalf of the Public Health Service. The qualitative performance test was based on pooled samples with different viral loads of SARS-CoV-2 or human Coronavirus OC43. 75% of the participating laboratories tested all core samples correctly, while the remaining 25% interpreted incorrectly the EQA exercise samples matching negatively the standards required. Subsequent inspection visits confirmed the issue of incorrect positive and negative certifications for COVID-19 by private and public laboratories, despite the possession of the authorization requirements currently provided for by current regulations, with a significant impact on the SSR.

The quality assurance of the measurement results generated by ISO/IEC 17025 testing and calibration laboratories is directly associated with monitoring the processes performed by their measuring instruments. This monitoring can be performed through the application of control charts, and, for this study, four electronic balances belonging to two different laboratories were chosen as the measuring instruments analyzed. The main goal of this research is to identify, among the cumulative summation (CUSUM) control charts, exponentially weighted moving average (EWMA) and Shewhart control charts, the most adequate to monitor the trends of these balances. It was necessary to define the periods of analysis of the data collected by the laboratories, to calculate the control limits of each chart (phase I), to carry out the monitoring of the process (phase II), followed by the comparison between the three types of control charts. The Minitab Statistical 17 software was used for the construction of these control charts. This study identified that the EWMA control chart is the best alternative to monitor trends at all points of the mid-check since it is the only one that can be used with both normal and non-normal data. However, it was not possible to identify which control chart detects the special causes earlier. [ABSTRACT FROM AUTHOR]

The recent advances of novel methodologies such as non-targeted and suspect screening based on high-resolution mass spectrometry (HRMS) have paved the way to a new paradigm for exposure assessment. These methodologies allow to profile simultaneously thousands of small unknown molecules present in environmental and biological samples, and therefore hold great promises in order to identify more efficiently hazardous contaminants potentially associated with increased risks of developing adverse health outcomes. In order to further explore the potential of these methodologies and push the transition from research applications towards regulatory purposes, robust harmonized quality standards have to be implemented. Here, we discuss the feasibility of using ISO/IEC 17025: 2017 as a guideline to implement non-targeted and suspect screening methodologies in laboratories, whether it is for accreditation purposes or not. More specifically, we identified and then discussed how specificities of non-targeted HRMS methodology can be accounted for in order to comply with the specific items of ISO/IEC 17025: 2017. We also discussed other specificities of HRMS methodologies (e.g., need for digital storage capacity) that are so far not included in the ISO/IEC 17025 requirements but should be considered. This works aims to fuel and expand the discussion in order to subsidize new opportunities of harmonization for non-targeted and suspect screening.

For accreditation of calibration laboratories, the standard reference is ISO/IEC 17025, which specifies the general requirements for competence, impartiality and consistent operation of laboratories. When analyzing various scopes of accreditation in different accreditation bodies, there was a significant variation in the Calibration and Measurement Capabilities (CMC) declaration for the same type of equipment. This article presents a critical analysis of factors that may have generated this variation. And consider the need to prioritize the adequacy of calibration methods to metrological characteristics of the equipment, in order to have less variation in the presentation of accreditation scopes.

New psychoactive substances (NPS) are uncontrolled analogues of existing drugs or newly synthesized chemicals that exhibit psychopharmacological effects. Due to their diverse nature, composition, and increasing prevalence, they present significant challenges to the healthcare system and drug control policies. In response, healthcare system laboratories have developed analytical methods to detect NPS in biological samples. As a Regional Reference Centre, the Sicilian CRQ Laboratory (Regional Laboratory for Quality Control) developed and conducted an External Quality Assessment (EQA) study to assess, in collaboration with the Istituto Superiore di Sanità (ISS), the ability of different Italian laboratories to identify NPS and traditional drugs of abuse (DOA) in biological matrices. Two blood samples were spiked with substances from various drug classes, including synthetic cannabinoids, cathinones, synthetic opiates, and benzodiazepines, at concentrations ranging from 2 to 10 ng/mL. The blood samples were freeze-dried to ensure the stability of DOA and NPS. Twenty-two laboratories from the Italian healthcare system participated in this assessment. The information provided by the laboratories during the registration in an in-house platform included a general description of the laboratory, analytical technique, and the chosen panels of analytes. The same platform was employed to collect and statistically analyze the data and record laboratory feedback and comments. The evaluation of the results revealed that the participating laboratories employed three different techniques for analyzing the samples: GC-MS, LC-MS, and immunoenzymatic methods. Approximately 90 % of the laboratories utilized LC-MS techniques. Around 40 % of false negative results were obtained, with the worst results in the identification of 5-chloro AB PINACA. The results showed that laboratories that used LC-MS methods obtained better specificity and sensitivity compared to the laboratories using other techniques. The results obtained from this first assessment underscore the importance of external quality control schemes in identifying the most effective analytical techniques for detecting trace molecules in biological matrices. Since the judicial authorities have not yet established cut-off values for NPS, this EQA will enable participating laboratories to share their analytical methods and expertise, aiming to establish common criteria for NPS identification. • NPS pose challengesto healthcare and drug control policies due to their diverse nature and increasing prevalence. • EQA study to evaluate the identification NPS and traditional drugs of abuse in biological matrices in Italian laboratories. • GC-MS, LC-MS, and immunoenzymatic methodswere reported, with LC-MS showing higher specificity and sensitivity. • The absence of cut-off values for NPS emphasizes the need to establish common criteria for their identification.

A laboratory must produce analytical data of sufficient precision and reliability within an acceptable time frame and at an allowable cost. For laboratories accredited by the 17025 standard, this objective becomes even more important, being the participation in Proficiency Testing (PT), as external quality control, the superior way of demonstrating their technical competence. DECA (formerly the Department of Studies on Environmental Pollution, today the Scientific-Technical Services Management Unit DECA), belonging to the National Center for Scientific Research in Cuba, with a long tradition of work in the field of the environment (including the characterization of water, wastewater and solid waste), achieved its first accreditation by the National Accreditation Body of the Republic of Cuba (ONARC, acronym in Spanish) in 2001 and has maintained a regular participation in PT. The objective of this work is to demonstrate the technical competence of the Unit of Management of Scientific-Technical Services (UG SCT-DECA, acronym in Spanish) in the analytical services it provides, through the results it has obtained from its continued participation in PT. Taking into account the PTs (national and international) in the period 2008-2019, different indicators were used to measure their performance, as well as graphic tools that allowed to visualize the behavior over time. The evidence demonstrates the technical competence maintained by DECA's analytical services, strengthening the quality and reliability of the results it brings to its clients, which has allowed the faithfulness of a considerable number of them.

Evaluating subcontractor competence in ISO/IEC 17025 standard is usually based on the readiness of equipment and manpower (RoEM) of laboratory involved in production activities. However, the risk of failure factors including the process of receiving samples, testing process and reporting test results to the customer have to be included. In this study, we present an integrating quality function deployment and failure mode and effect analysis in subcontractor selection for ISO/IEC 17025 standard. The ranking of all subcontractors is based on the different weights of the RoEM and the risk priority number. A case study with three scenarios is used to illustrate the applicability of the proposed method. [ABSTRACT FROM AUTHOR]

Background: It is predictable that the laboratories with many years of accreditation should get lower amount of nonconformities than those of the new ones. The objectives of the study are to find the differences in characteristics and nonconformities among ISO/IEC 17025 accredited laboratories undergoing on-site assessment in 2015 and verify the above prediction. Materials and methods: A cross-sectional study of the characteristics and the nonconformities from 2015 assessment of 134 laboratories were compared between the laboratories with 6 or more years or at least 3 cycles of accreditation and the ones with shorter accreditation year. Statistical analyses were done by using Stata-intercooled version 6. Results: There were 1,459 total nonconformities, 572 (39%) were those against management requirements and 887 (61%) were those from technical ones. Longer and new accredited laboratories shared similar basic characteristics. Longer accredited laboratories got lower total nonconformities (mean±SD; 9.1±4.8 vs 12.7±9.0: t-test=2.89, p=0.003), and lower technical nonconformities (mean±SD; 5.0±3.1 vs 8.3±6.9: t-test=3.57, p

An accurate gas chromatography coupled to a flame ionization detector (GC-FID) method was validated for the simultaneous analysis of light hydrocarbons (C2-C4) in their gas mixture. The validation parameters were evaluated based on the ISO/IEC 17025 definition including method selectivity, repeatability, accuracy, linearity, limit of detection (LOD), limit of quantitation (LOQ), and ruggedness. Under the optimum analytical conditions, the analysis of gas mixture revealed that each target component was well-separated with high selectivity property. The method was also found to be precise and accurate. The method linearity was found to be high with good correlation coefficient values (R2 ≥ 0.999) for all target components. It can be concluded that the GC-FID developed method is reliable and suitable for determination of light C2-C4 hydrocarbons (including ethylene, propane, propylene, isobutane, and n-butane) in their gas mixture. The validated method has successfully been applied to the estimation of hydrocarbons light C2-C4 hydrocarbons in natural gas samples, showing high performance repeatability with relative standard deviation (RSD) less than 1.0% and good selectivity with no interference from other possible components could be observed.

The growing demand for traceable and reliable results in analytical chemistry can be illustrated with the growth in ISO/IEC 17025 accreditation. Among different technical requirements in this quality system, the use of CRMs is highlighted because of its applications in many operations, such as method validation, proficiency tests, estimation of the uncertainties and quality control. Over the past several years, there has been an increased need to use different types of CRMs in chemical analysis, new CRM publications about its developments and certification. This paper proposes to show a detailed review considering the development of certified reference materials (CRM) for chemical analysis, focusing on food, water, soil and sediment matrices. An evaluation of the trends and best-applied practices in its development in the last 2 years was performed, to guide new developments for this material that is increasingly necessary to laboratories.

Translation abstract: In order to achieve trusted results calibration of material testing machines is the required. The results have to be traceable to national standards. According to the state of technology this is mostly done by accredited labs. The uncertainty of measurements is calculated and taken into consideration. The corresponding procedure is demonstrated on the basis of the calibration of material testing machines ‐ taking the uncertainty into account without worsening of the class of the machine – and in consideration of ISO/IEC 17025. This can be verified on closer examination of the results of calibration for one machine over the last 60 years. [ABSTRACT FROM AUTHOR]

The situation on the market of laboratory services in Poland is growing rapidly. In order to stay in this difficult market, one shall convince potential customers to his/her competences and quality of services. Testing or calibration laboratories, wishing to assert its position in the market, introduce the management system based on the PN-EN ISO/IEC 17025:2005 standard, the so-called ‘General requirements for the competence of testing and calibration laboratories’, and then apply for the certificate of accreditation in the Polish Centre for Accreditation (PCA) [14].

Universities are considered as a source of open innovations by producing new technology. The innovations need to be tested in licensed laboratories in order to create certified products if they are to be commercialized to the market. Many universities have established laboratories that provide testing services to society and act as a revenue-generating source. Universitas Sebelas Maret (UNS) owns an accredited center laboratory that provides testing services to external parties. In addition, the university owns other laboratories in several faculties to conduct academic activities and research and yet provide testing services, but have not been accredited. Therefore, the laboratories have the potential to be developed as part of the testing service business to support the incubation process of new technology and provide testing services. In this article, we chose UNS, one of the universities in Indonesia, to develop a framework of readiness level measurement instrument, to evaluate the readiness and to suggest improvements for laboratories to achieve accreditation. A framework of laboratory readiness measurement was developed using integration of management approach and laboratory approach. Descriptive statistics were used to create a radar chart to determine the readiness level. Based on findings and evidence analysis, we proposed improvement planning using ISO 17025 and management concept.

The international standard, ISO/IEC 17025 was developed to determine technical competence and to evaluate laboratories throughout the world. Accreditation bodies playing a vital role are increasingly using proficiency testing methodology as a tool to ensure the credibility of their accreditation programs. The successful completion of a well-designed proficiency test can validate the measurement method and uncertainty budgets of a testing laboratory. Additionally, proficiency tests can provide a good indication about the quality of the test results. An important part of inter-laboratory comparisons and proficiency testing is the determination of the associated error analyses which are focused on uncertainty values. This paper presents the implementation of proficiency tests using inter-laboratory methodology among five different acoustic laboratories. These tests were carried out on 5.27 KWCooling standard unitary air conditioner, A/C, such as through-wall or split room standard A/C units, for the assessment of Housing & Building National Centre acoustic laboratory. Analyses of results show a good agreement for En-Value among the selected laboratories when compared with the lowest uncertainty as stated by proficiency tests standards.
