Scope

This document assesses the long-term susceptibility to light of materials and treatments used inconservation of porous inorganic materials. Examples may include materials which have been treated inthe course of conservation (e.g. cleaning, consolidation, water repellents, coatings or biocides) ormaterials which may exhibit colour changes following exposure (e.g. mortars and small number ofstones). The procedure can be used to evaluate the impact and longevity/durability of treatmentsagainst untreated materials or unexposed materials.\NOTE 1 Porous inorganic materials are both natural stones (rocks) and artificial stone materials (mortars,stuccoes, bricks, ceramic materials, etc.).NOTE 2 Treated materials are those on which one of the following treatments has been applied: cleaning,application of water repellent, consolidating materials, coatings or biocides and artificial ageing.
