ASTM G92-2020适用范围

1.1''This practice covers procedures for the characterization of atmospheric test sites. Continuous characterization can provide corrosion data, environmental data, or both which will signal changes in corrosivity of the atmospheric environment. This practice can also provide guidance for classification of future test sites.

1.2''Two methods are defined in this practice for the characterization of atmospheric test sites. The methods are identified as characterization Methods A and B. The preferred characterization technique would require using both Method A and B for concurrent data collection.

1.2.1''Method A is to be used when atmospheric corrosion is monitored on a continuing basis at a test site using specified materials and exposure configurations.

1.2.2''Method B is specified when atmospheric factors are monitored on a continuing basis.

1.3''The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4''This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5''This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

1.1“本实施规程涵盖了大气试验场地的表征程序。连续表征可以提供腐蚀数据和/或环境数据，这将表明大气环境腐蚀性的变化。该实践还可为未来试验场地的分类提供指导。

1.2本实施规程中定义了两种方法，用于大气试验场地的表征。这些方法被确定为表征方法A和B。首选表征技术要求同时使用方法A和B进行数据收集。

1.2.1当使用规定的材料和暴露配置在试验现场连续监测大气腐蚀时，应使用“方法A”。

1.2.2当连续监测大气因素时，规定了“方法B”。

1.3“以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。

1.4“本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。

1.5“本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。
