DIN EN 17036:2018-08

This document assesses the long-term susceptibility to light of materials and treatments used in conservation of porous inorganic materials. Examples may include materials which have been treated in the course of conservation (e. g. cleaning, consolidation, water repellents, coatings or biocides) or materials which may exhibit colour changes following exposure (e. g. mortars and small number of stones). The procedure can be used to evaluate the impact and longevity/durability of treatments against untreated materials or unexposed materials.
