ASTM G92-2020適用范圍

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“本實施規(guī)程涵蓋了大氣試驗場地的表征程序。連續(xù)表征可以提供腐蝕數(shù)據(jù)和/或環(huán)境數(shù)據(jù)，這將表明大氣環(huán)境腐蝕性的變化。該實踐還可為未來試驗場地的分類提供指導(dǎo)。

1.2本實施規(guī)程中定義了兩種方法，用于大氣試驗場地的表征。這些方法被確定為表征方法A和B。首選表征技術(shù)要求同時使用方法A和B進行數(shù)據(jù)收集。

1.2.1當使用規(guī)定的材料和暴露配置在試驗現(xiàn)場連續(xù)監(jiān)測大氣腐蝕時，應(yīng)使用“方法A”。

1.2.2當連續(xù)監(jiān)測大氣因素時，規(guī)定了“方法B”。

1.3“以國際單位制表示的數(shù)值應(yīng)視為標準值。本標準不包括其他計量單位。

1.4“本標準并非旨在解決與其使用相關(guān)的所有安全問題（如有）。本標準的使用者有責任在使用前建立適當?shù)陌踩⒔】岛铜h(huán)境實踐，并確定監(jiān)管限制的適用性。

1.5“本國際標準是根據(jù)世界貿(mào)易組織技術(shù)性貿(mào)易壁壘（TBT）委員會發(fā)布的《關(guān)于制定國際標準、指南和建議的原則的決定》中確立的國際公認標準化原則制定的。
