This method can also be used to determine the fogging characteristics of raw material

12、s in fluid, paste, powdered and solid form which constitute the trim materials or from which they are manufactured. NOTE Measurements of raw materials do not necessarily provide information on the fogging characteristics of the parts made from these materials. 2 Normative references The following re

18、during the fogging process can impair visibility through the windscreen. DIN 75201:2011-11 5 3.2 fogging value F quotient of the 60 specular gloss value for a glass plate with fogging condensate and the 60 specular gloss value for a glass plate without fogging condensate NOTE 1 See the Explanatory N

20、ance: DIN ISO 2768-1 c 5 Short description of methods 5.1 Method A The test specimen or sample is placed on the bottom of a glass beaker without a pouring spout and of specified size (referred to below as “beaker”). The beaker is covered with a glass plate on which volatile components released by th

21、e specimen or sample can condense. This glass plate is cooled. The beaker is then immersed for 3 h in a thermostatically controlled bath set to a test temperature of (100 0,3) C. The effect of fogging condensate on the glass plate is determined by measuring the 60 specular gloss. The 60 specular glo

22、ss for the same glass plate that is free from fogging condensate and carefully cleaned before the test is used as a reference value. NOTE In deviation from DIN EN ISO 2813 the specular gloss is only measured at a 60 angle (DIN EN ISO 2813 specifies that very high gloss samples are measured at a 20 a

23、ngle, medium gloss samples at a 60 angle and near-matt samples at a 85 angle). 5.2 Method B The test specimen or sample is placed on the bottom of a glass beaker without a pouring spout and of specified size (referred to below as “beaker”). The beaker is covered with a sheet of aluminium foil on whi

24、ch volatile components released by the specimen or sample can condense. This aluminium foil is cooled. The beaker is then immersed for 16 h in a thermostatically controlled bath set to a test temperature of (100 0,3) C. The mass of the fogging condensate on the aluminium foil is quantitatively deter

25、mined by weighing the aluminium foil before and after the fogging test.

They shall be marked on their upper surface to match the marking on the backing plate. NOTE The tolerances for the thickness across

38、 a glass plate result in a considerable scattering of the R0ivalues. To achieve a low overall scatter, it is necessary to correlate pairs of specular gloss values determined before and after the fogging test. 7.2.5 Auxiliary equipment for method B Glass plates or borosilicate glass plates, thickness
