标准摘要
[中文适用范围]： 本国际标准描述了在恒电位控制下测定不锈钢（奥氏体、铁素体/奥氏体、铁素体不锈钢）临界点蚀温度的程序。 该测试的主要优点是可以在单次测试中快速测量临界点蚀温度。 本国际标准中确定的临界点蚀温度可用作相对性能指标，例如用于比较不同等级不锈钢的相对性能。 本国际标准中描述的测试并非旨在确定使用中发生点蚀的温度。 [外文原描述]： ISO 17864:2005 describes the procedure for determining the critical pitting temperature for stainless steels (austenitic, ferritic/austenitic, ferritic stainless steel) under potentiostatic control. The principal advantage of the test is the rapidity with which the critical pitting temperature can be measured in a single test. The critical pitting temperature, as determined in this International Standard, can be used as a relative index of performance, for example, to compare the relative performance of different grades of stainless steel. The test described in this International Standard is not intended to determine the temperature at which pitting will occur in service.
