Scope

This document specifies the open carbon arc lamp test method for specimens exposed to wet conditions, which is used to reproduce the natural behavior of simulated materials exposed to solar radiation or solar radiation filtered by window glass in the actual use environment. aging effect. This document is applicable to the weather resistance evaluation of plastics and the comparison test of weather resistance among plastics under the condition of carbon arc lamp light source exposure. The samples were exposed to a filtered open carbon arc lamp under controlled environmental conditions (temperature, humidity). There are a variety of filters to choose from. Specimen preparation and result evaluation for specific materials refer to other national standards. ISO 4892 1 gives general principles.
