Scope

This document specifies requirements and test methods for evaluation of the permanence and durability of self-adhesive paper-based labels intended for labelling of archive boxes made of solid and corrugated paper board and other storage materials, such as metal or plastic, stored in libraries, archives, and other protected environments for long periods of time.

It is applicable to:

—     labels stored in archival conditions according to ISO 11799 , i.e. dry, cool, dark and no contact with water

—     labels made of permanent paper according to ISO 9706

—     labels with acrylate-based adhesive without plasticizers or other additives that can migrate into the surrounding layers

—     written or printed images obtained from pens, copying machines and printers that meets the requirements in ISO 11798

—     the substrate of intended use, i.e. sample substrate used for testing

—     archive boxes made of cardboard that meets the requirements in ISO 16245

—     substrates with a smooth and even surface with a Bentsen roughness of maximum 2000 ml/min

It does not apply to:

—     labels stored under harmful conditions, such as high humidity that promotes microbiological attack, excessive heat, radiation (e.g. light), high levels of pollutants, or the risk of water damage.

—     labels with non-permanent paper

—     labels with adhesive other than acrylate-based

—     other substrates than intended use

—     substrates with rough or uneven surface

The result for the adhesion testing is strictly a combination of the selected substrate and the label.
