1.1 本规程涵盖了为试验准备裸露固体金属试样、在试验完成后去除腐蚀产物以及评估已发生腐蚀损伤的建议程序。重点放在通过质量损失和点蚀测量评估腐蚀的相关程序上。( 警告- 在许多情况下，活性金属钛和锆上的腐蚀产物是一种坚硬且紧密结合的氧化物，难以通过化学或普通机械手段去除。在许多情况下，腐蚀速率是由质量增益而不是质量损失确定的。 ) 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）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 有关特定警告声明，请参阅 1.1 和 7.2 . 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。 ====意义和用途====== 4.1 给出的程序旨在去除腐蚀产物，而不会显著去除基底金属。这允许准确测定暴露在腐蚀环境中的金属或合金的质量损失。 4.2 在某些情况下，这些程序可能适用于金属涂层。然而，必须考虑基板的可能影响。

1.1 This practice covers suggested procedures for preparing bare, solid metal specimens for tests, for removing corrosion products after the test has been completed, and for evaluating the corrosion damage that has occurred. Emphasis is placed on procedures related to the evaluation of corrosion by mass loss and pitting measurements. ( Warning— In many cases the corrosion product on the reactive metals titanium and zirconium is a hard and tightly bonded oxide that defies removal by chemical or ordinary mechanical means. In many such cases, corrosion rates are established by mass gain rather than mass loss.) 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. For specific warning statements, see 1.1 and 7.2 . 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. ====== Significance And Use ====== 4.1 The procedures given are designed to remove corrosion products without significant removal of base metal. This allows an accurate determination of the mass loss of the metal or alloy that occurred during exposure to the corrosive environment. 4.2 These procedures, in some cases, may apply to metal coatings. However, possible effects from the substrate must be considered.
