ASTM G69-2020适用范围

1.1 This test method covers a procedure for measurement of the corrosion potential (see Note 1) of an aluminum alloy in an aqueous solution of sodium chloride with enough hydrogen peroxide added to provide an ample supply of cathodic reactant.

NOTE 1:The corrosion potential is sometimes referred to as the open-circuit solution or rest potential. See Terminology G193.

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

1.3 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.

1.4 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.

注1:腐蚀电位有时称为开路电位或静止电位。见术语G193。

1.2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。

1.3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。

1.4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。

1.1本试验方法包括测量铝合金在氯化钠水溶液中的腐蚀电位(见注1)的程序,该溶液中添加了足够的过氧化氢,以提供充足的阴极反应物。
