ISO/DIS 25650:2026

This document specifies requirements and test methods for evaluation of the permanence and durability of self-adhesive labels intended for labelling of archive boxes (paper board) and other storage materials (such as metal or plastic) stored in libraries, archives, and other protected environments for long periods of time. The labels must retain their adhesion capability, and the permanence of images on them must be equivalent to that of images on permanent paper. It is applicable to: — labels stored in archival conditions (dry, cool, dark and no contact with water) — labels made of permanent paper (ISO 9706) or archival paper (ISO 11108) in combination with acrylate-based adhesive — written or printed images obtained from pens, copying machines and printers that meets the requirements in ISO 11798 — the substrate of intended use (sample substrate used for testing) 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 (or water contact). — labels with non-permanent paper or other adhesive than acrylate-based — other substrates than intended use
