本文件给出了暴露在深海中的金属和合金的腐蚀试验指南，包括试验地点的选择、试验系统的组件和组装、试样制备、试验程序、从暴露地点检索后的评估和试验报告。 本文件适用于金属和合金的一般腐蚀暴露试验，以及局部腐蚀试验，如暴露在深海中的试样的应力腐蚀开裂（SCC）试验、电偶腐蚀试验和缝隙腐蚀试验。 也可以参照这些指南进行其他材料（如复合材料和弹性体）的深海暴露试验，但回收后对这些材料的评估不同于金属和合金。 本文件不包括深海阴极保护用牺牲阳极的性能测试，可使用指定的深海测试电池和设备进行测试- 海上暴露。然而，本指南也可以为深海中牺牲阳极的性能测试提供有用的参考信息。

This document gives guidelines for the corrosion testing of metals and alloys exposed in deep-sea water, including the selection of the test site, components and assembly of the test system, specimen preparation, testing procedure, evaluation after the retrieval from exposure sites and test report. This document is applicable to the general corrosion exposure testing of metals and alloys as well as localized corrosion tests such as stress corrosion cracking (SCC) testing, galvanic corrosion testing and crevice corrosion testing of specimens exposed in deep-sea water. Testing with exposure in deep sea of other materials such as composites and elastomers can also be carried out with reference to these guidelines, but the evaluation of these materials after the retrieval is different from that of metals and alloys. This document does not include the performance testing of sacrificial anodes for cathodic protection in the field of deep sea, which can be conducted using specified testing cells and equipment in the deep-sea exposure. However, this guidance can also provide useful information as reference for conducting performance testing of sacrificial anodes in deep-sea water.
