DANSK DS/ISO 18951-2 PDF

This document specifies test parameters, test procedures, test targets, and reporting requirements for determining the scratch resistance of photographic prints using the sclerometer test method. It is applicable to photographic prints that have no protection as well as photographic prints that are protected by a coating or lamination. It is specifically useful as a low-cost, easily implemented procedure for evaluating scratch resistance of these prints. It is not the purpose of this document to define limits of acceptability or failure. They would be determined by the user and the intended application.
