32、he colour measurement procedure has been revised.iv ISO 2017 All rights reserved ISO 4582:2017(E)IntroductionA number of different exposure techniques can be used to provide information on the effects of environmental stresses such as simulated solar radiation, heat and water on plastics see ISO 877

33、 (all parts) and ISO 4892 (all parts). Each exposure test has its own particular application and relevance. When determining changes in a particular property or attribute of a material subjected to different exposures, the same evaluation methods should be used after all exposures to ensure meaningf

34、ul results.Results for plastics subjected to exposure tests are strongly dependent on the type of exposure conditions used, the type of plastic being tested and the property being evaluated. A result obtained for one property may not be the same as that for a different property of the same material,

35、 even if the same exposure test is used. This document is not intended to establish a fixed procedure for conducting the exposure test, but is intended to provide a set of specific procedures used to express the results for change in a characteristic property of the material after it has been expose

36、d. It is up to the user to determine which exposure conditions are most relevant to the specific material and the service conditions being used.Test methods should be selected to determine changes in appearance and properties of the exposed material with its proposed application in mind. The exposur

37、e test used should be devised to discriminate among materials based on such changes. This document suggests typical properties that can be used to determine changes in plastics which have been subjected to exposure tests.NOTE Because of large differences in the spectral distribution of the radiation

38、 sources used, there can be large differences in results for the same plastics exposed in the various devices described in ISO 4892 (all parts). Therefore, comparisons between plastics are intended to be made only based on results from exposures in the same type of device and under the same conditio

39、ns. For optimum comparisons, plastics are expected to be exposed at the same time in the same device.
