意义及用途
5.1 The use of the equipment is intended to cause changes in performance consistent with the conditions of final use, including the effects of the ultraviolet portion of sunlight, moisture and heat. 通常, these exposures will include moisture in the form of condensing humidity. 暴露并非旨在模拟由当地天气现象（例如大气污染）引起的恶化, 生物攻击, 和盐水暴露. Alternatively, exposure can simulate the effects of sunlight passing through a window pane. (警告 – See Practice G151 for a complete warning guide for all laboratory aging equipment.

5.2 This practice provides general procedures for operating fluorescent UV lamp aging devices that allow for a wide range of exposure conditions. Consequently, no reference to the results of the use of this approach may be made unless accompanied by a report detailing the specific operating conditions of section 10.

5.2.1 It is recommended that similar materials (控制) with known properties be exposed at the same time as the sample to provide a standard for comparison purposes. 一般来说, it is recommended to use two controls: one known to have poor durability and the other known to have good durability. It is recommended that at least three replicates of each evaluated material be performed in each test to allow for statistical evaluation of the results.

5.2.2 Results obtained from exposed specimens in the same model of equipment should not be compared unless repeatability of the material to be tested has been established between devices.

5.2.3 Results obtained from exposed specimens from different models of equipment should not be compared unless a correlation of the material to be tested has been established between the devices.

半径
1.1 This practice is limited to the basic principles of operating fluorescent UV lamps and water installations; 通过它自己, 它没有提供具体结果.

1.2 它旨在与定义应用的特定暴露条件和评估材料特性变化的方法的实践或方法结合使用. This practice aims to reproduce the weathering effects that occur when the material is exposed to sunlight (直接或通过窗玻璃) 和水分 (such as rain or dew) 实际使用过程中. 这种做法仅限于获得, 测量, 和控制曝光条件.

笔记 1: Practice G151 describes general procedures to be used when exposing non-metallic materials in accelerated test equipment using laboratory light sources.

笔记 2: A number of exposure procedures are listed in the Appendix; 然而, 这种做法没有规定待测材料的适当暴露条件.

1.3 Test samples are exposed to fluorescent UV light under controlled environmental conditions. Different types of fluorescent UV lamp sources are described.

笔记 3: 在本标准中, the terms ultraviolet and ultraviolet radiation are used interchangeably.

1.4 ASTM 方法或特定材料规范涵盖了样品制备和结果评估. General guidance is given in Practice G151 and ISO 4892-1.

笔记 4: 国际标准化组织 4582 and Practice D5870 describe general information on methods for determining post-exposure performance changes and reporting these results.

1.5 以 SI 单位表示的值应视为标准值. 本标准不包含其他计量单位.

1.6 本标准并非旨在解决所有安全问题, 如果有的话, 与其使用相关. 本标准的使用者有责任建立适当的安全和健康实践，并在使用前确定监管限制的适用性.

1.7 This standard is technically similar to ISO 4892-3 和ISO 16474-3.
