Plastics - Methods of exposure to laboratory light sources - Part 2: Xenon-arc lamps (ISO 4892-2:2006 + Amd.1:2009); German version EN ISO 4892-2:2006 + A1:2009
This amendment specifies eight additional exposure cycles in the new Table 4 where the temperature control is by a black-panel thermometer rather than a black-standard thermometer. The black-panel temperatures specified in Table 4 and the black-standard temperatures specified in Table 3 are those most commonly used but have no relationship to each other. Therefore, the test results may not be comparable.
