This report presents the ICP Materials database for the period October 2020 to December 2021. It includes environmental data from the ICP Materials trend exposure programme for 2020 - 2021 and, in addition, data for temperature, relative humidity, and precipitation amount back to the end of the previous annual exposure programme in October/November 2018. The database consists of meteorological data (T, RH and precipitation amount) and pollution data: Gas concentrations, amounts of ions in precipitation, particle concentrations and amounts of particle deposition. Denne rapporten presenterer databasen i ICP Materialer for perioden oktober 2020 – desember 2021. Den inkluderer miljødata fra ICP Materialer trend-eksponeringsprogrammet for 2020 – 2021 og, i tillegg, data for temperatur, relativ fuktighet og nedbørsmengde tilbake til slutten av forrige årlige eksponeringsperiode i oktober/november 2018. Databasen består av meteorologiske data (T, RF og nedbørsmengde) og forforurensningsdata: Gasskonsentrasjoner, mengde ioner i nedbør, partikkelkonsentrasjoner og mengde avsatte partikler.

Korrosjonsklasse ble beregnet på lokasjon (59°56'11.5"N 5°19'58.4"Ø) i Fitjar, Vestland, Norge, fra årsgjennomsnitt for miljøparametere etter ISO 9223 og ISO 12944-2. Det ble funnet at korrosjonsklassen med høy sannsynlighet er C3 og at dette i hovedsak er bestemt av våt-tiden på omtrent 4500 timer/år, som gjennomsnitt i perioden 2007-2022. Dette er godt innenfor grensene for C3 når saltavsetningen er < 60 mg Cl-/m2døgn og SO2 konsentrasjonen i luft < 30 µg/m3. Disse betingelsene synes med stor sannsynlighet oppfylt på lokasjonen i Fitjar som årsgjennomsnitt i normalår. The corrosion class was estimated on location (59°56'11.5"N 5°19'58.4"Ø) in Fitjar, Vestland, Norway, from annual average environmental values, based on ISO 9223 and ISO 12944-2. It was found that the corrosion class was, with high probability, C3, and mostly determined by the time of wetness (TOW) of about 4500 h/a, as an average for the years 2007-2022. This is well within the limits of C3 when the sea-salt deposition is < 60 mg Cl-/m2day (24 hours) and the SO2-concentration in air < 30 μg/m3. These conditions seem satisfied with a high probability on the location in Fitjar, as annual averages in normal years.

Ed. by: Elin M. Dahlin. The MEMORI project (Grant agreement 265132) was performed in the period 2010-2013. The project was coordinated by NILU - Norwegian Institute for Air Research and included 14 partners, four subcontractors and an advisory end-user group with 8 members. MEMORI aimed at providing the conservation market with innovative, non-destructive, and early warning technology for easy assessment of environmental impact on indoor cultural heritage. For this purpose, a dosimeter and a portable reader instrument were produced. In addition, a new web-based result’s and presentation mitigation tool was developed.

This report presents the ICP Materials database for the period October 2011-December 2012. It includes environmental data from the ICP Materials trend exposure programme for 2011 - 2012. The database consists of meteorological data (T and RH), and pollution data as gas concentrations, amounts of ions in precipitation, particle concentration and amount of particle deposition.

NILU - Norsk institutt for luftforskning og NIKU - Norsk institutt for kulturminneforskning har etter søknad fått støtte av Riksantikvaren til å utarbeide et notat som belyser kunnskapsbehov i Norge relatert til fysisk bevaring av kulturminner. Identifying knowledge gaps in physical preservation of Cultural Heritage prior to 2020

An overview is given of all results from the International Co-operative Programme on Effects on Materials including Historic and Cultural Monuments (ICP Materials), which was launched in 1985. Since then, about twenty different materials have been exposed repeatedly in a network of test sites consisting of more than twenty sites with an extensive environmental characterisation and more than sixty official reports have been issued. Recent results on trends in corrosion, soiling, and pollution show that corrosion of carbon steel, zinc, and limestone is today substantially lower than 25 years ago, but while corrosion of carbon steel has decreased until today, corrosion of zinc and limestone has remained more or less constant since the turn of the century. Unique data are given on measured HNO3 concentrations from 2002-2003, 2005-2006, and 2008-2009, and the relative average decrease was about the same from 2002-2003 to 2005-2006 as it was from 2005-2006 to 2008-2009.

This report presents the ICP Materials database for the period October 2008-December 2009. It includes environmental data from the ICP Materials trend exposure programme for 2008 - 2009. The database consists of meteorological data, and pollution data as gasses and in precipitation. Also reported are HNO3 and amount and composition in particle deposition in soiling.
