This document describes a test method for conservation materials which can evaluate their impact on cellulose as the main constituent of paper-based collections caused by emission of their volatile compounds.<\/p>\n

\n
\n NOTE\n <\/div>\n

This test can be extended to museum artefacts.<\/p>\n<\/div>\n

This document is applicable to papers and boards used for conservation and storage of cellulose based items.<\/p>\n

It is not applicable to parchment-based items.<\/p>\n

It does not evaluate the effects due to direct contact between the papers and boards used for conservation and the collections.<\/p>\n
