Introduction

A variety of different exposure methods can provide information on the impact of external environmental conditions (such as simulated solar radiation, heat, water, etc.) on plastics [Reference ISO 877 (all parts) and ISO 4892 (all parts)]. Each exposure test has its specific scope of application. When the measuring material is When a specific performance changes under different exposures, in order to ensure the validity of the test results, the same evaluation method should be used after all exposures. The results of the plastic exposure test largely depend on the type of exposure test, the type of plastic being tested, and the performance being evaluated. Even though Under the same exposure test conditions, the test results of a certain property of the material may be inconsistent with the test results of other properties. This document is not for It establishes a fixed method to guide the exposure test, but to provide a set of characteristics used to express the results of the material performance change after the exposure test. Set procedures. It is up to the user to determine which exposure test conditions are most suitable for the specific material and the environment in which it is used. Taking into account the expected application of the material, a test method for determining the appearance and performance changes of the exposed material should be selected. Designed exposure test It should be judged by combining these changes in material properties. This document recommends some typical properties used to determine changes in exposed plastics. Note. Due to the large differences in the spectral distribution of the radiation sources used, the same plastic is exposed to different types of equipment described in ISO 4892 (all parts) There may be large differences between the test results obtained. Therefore, only plastics can be exposed to similar test equipment and the same test conditions. Compare its test results. In order to achieve the best comparison effect, plastics should be exposed simultaneously in the same test equipment. Solar radiation and natural climate after plastic is filtered by glass Or changes in color and performance after exposure to laboratory radiation sources Determination of

1 Scope

This document specifies the color of plastic after exposure to solar radiation, natural climate or laboratory radiation sources that simulate solar radiation after glass filtration And other appearance performance, mechanics or other performance changes measurement methods. The method of analyzing the data depends on the performance evaluation test of the exposed material Whether the test is destructive or non-destructive. The exposure test is carried out under the specified conditions of specific exposure standards.
