1.1 本试验方法涵盖了在铜上产生腐蚀产物粘附膜的电触点大气腐蚀试验室的校准，例如由与铜反应的流动气体混合物组成的试验。 1.2 本试验方法不适用于在试验过程中通过流体从铜表面去除腐蚀产物的试验。 1.3 本试验方法不适用于试验过程中可能在铜表面沉积气载固体或液体材料的试验，例如在包括悬浮在大气中的颗粒的试验中。 1.4 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。 1.5 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熟悉所有危险，包括制造商提供的本产品/材料的适当安全数据表（SDS）中确定的危险，建立适当的安全、健康和环境实践，并在使用前确定监管限制的适用性。 1.6 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 包含电触点的电气设备通常包含一些铜基材料。在使用环境中，此类设备中的铜部件经常发生大气腐蚀。实验室腐蚀试验对铜影响的定量测量允许评估试验的严重性。此外，腐蚀试验可以根据其对铜的影响来定义；该测试方法提供了一种将一个测试与其他地方定义的标准进行比较的方法，或允许在一段时间内比较测试的性能。尽管本试验方法提供了相对简单的试验检查，但建议用户通常需要对试验箱环境进行额外分析，以再现试验条件。 4.2 除铜外，还对各种材料进行了大气腐蚀试验。如果气体成分或实验条件不同，则在得出明显等效试验对此类材料影响的结论时应小心。该校准测试方法的主要用途是确保名义上相同的测试之间的相关性。

1.1 This test method covers the calibration of atmospheric corrosion test chambers for electrical contacts that produce an adherent film of corrosion product on copper, such as a test comprised of a mixture of flowing gases that react with copper. 1.2 This test method is not applicable to tests where corrosion products may be removed from a copper surface during the test by fluids. 1.3 This test method is not applicable to tests where airborne solid or liquid material may be deposited on a copper surface during the test, as in a test which includes particulates suspended in the atmosphere. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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 become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use. 1.6 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 Electrical devices that contain electrical contacts generally contain some copper-based materials. Atmospheric corrosion of copper parts in such devices often occurs in service environments. A quantitative measure of the effect of a laboratory corrosion test on copper permits assessment of the severity of the test. In addition, corrosion tests may be defined in terms of their effect on copper; this test method provides a way of comparing one test against a standard defined elsewhere, or allows a comparison of the performance of a test over a period of time. Although this test method provides for a relatively simple check of a test, the user is advised that additional analysis of the test chamber ambient is generally required to reproduce test conditions. 4.2 Atmospheric corrosion tests are used on a variety of materials besides copper. Care should be exercised in drawing conclusions about the effects on such materials of apparently equivalent tests if the composition of gases or experimental conditions are different. The primary use of this calibration test method is to assure correlation among nominally identical tests.
