23、:2018EN 17036:2018 (E) 4 Introduction In contrast to natural weathering, artificial ageing using simulated solar radiation involves a limited number of variables which can be controlled more readily and which are intensified to evaluate in a short way the stability of porous inorganic materials and

24、the durability of conservation treatments. The ageing processes which occur during artificial and natural weathering cannot be expected to correlate exactly with each other because of the large number of factors influencing these processes. Definite relationships can only be expected if the importan

25、t parameters (distribution of the irradiance over the photochemical relevant part of the spectrum, temperature of the specimen, type of wetting and wetting cycle, and relative humidity) are the same in each case or if their effect on the coatings is known. No direct correlation can be made between a

26、rtificial ageing duration and actual exposure duration. However, performance comparisons under the controlled conditions of artificial weathering can be compared to documented performance of materials and coatings that have experienced extended periods of end use exposure. This methodology is intend

27、ed to be used on new materials. In all cases, the risk of potential damage to irreplaceable objects during irradiation should be considered. BS EN 17036:2018EN 17036:2018 (E) 5 1 Scope This document assesses the long-term susceptibility to light of materials and treatments used in conservation of po

28、rous 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 proced

29、ure can be used to evaluate the impact and longevity/durability of treatments against 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 mate

30、rials 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. 2 Normative references The following documents are referred to in the text in such a way that some or all of their

Test apparatuses shal

The role of this filter is to simulate the filtering effect of the atmosphere. In addition, different filters with higher
