This Japanese Industrial Standard specifies methods of exposing plastics to solar radiation, either by direct exposure to natural weathering (hereafter referred to as Method A), to indirect solar radiation by modification of its spectral distribution with glass to simulate ageing of plastics behind building or automotive window glass (hereafter referred to as Method B), or to solar radiation intensiffied by the use of Fresnel mirrors to achieve acceleration of the weathering processes (hereafter referred to as Method C). The purpose is to assess changes produced after specified stages of such exposures. This Standard specifies the general requirements for the apparatus and operating procedures for using the test methods described. Although this Standard does not included direct weathering using black-box test fixtures, attention is drawn to this method of exposure testing of materials under conditions simulating their end-use temperatures.
