意义和目的
5.1 该测试方法提供了确定玻璃危险级别的结构化程序, glass systems and glass retrofit systems subjected to air explosion loads. Knowing the hazard level allows assessing the risk of personal injury and damage to facilities.

5.2 glass or glass material level does not mean that the danger of a single sample can resist its rating of 1.0 specific air blast. The probability that an individual glass or glass building specimen resists its rated specific air explosion increases in proportion to the number of specimens that successfully resist a given air explosion level up to its rated hazard level.

ASTM F1642-2017 空气流负载下门窗玻璃和玻璃装配系统的标准测试方法

范围
1.1 This test method specifies procedures for assessing the hazard of glass or glass systems to air explosive loads. The designated organization shall provide the air explosion load parameters. The glass system shall be as defined in Specification F2912.

1.2 from the method of the data obtained from the test is applied to use standard F2912 sure glass or glass, glass system transformation system risk level.

1.3 this test method allows with or without a frame system of glass for testing and rating.

1.4 the test method is designed to test and evaluation system of all glass, glass and glass systems, 包括但不仅限于, made of glass, 塑料, plastic cladding glass, sandwich glass, glass/plastic materials, organic coating glass and other are not directly connected to the glass or glass glass transformation system, such as explosion-proof, cable grid, shadows, and architecture.

1.5 Units-Values expressed in SI units or inch-pound units should be treated separately as standard values. 每个系统中指定的值可能不完全相同; 所以, 每个系统应相互独立使用. Merging values from both systems may result in non-compliance with the criteria. For the conversion of quantities in various measurement systems to SI units, see specification E699.

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. 该国际标准的使用者有责任建立适当的安全和健康实践, and determine regulations limit the applicability of before use. 参见章节 7 有关特定危险的描述.
