标准摘要
[中文适用范围]： 本文件规定了一种对不锈钢和相关合金暴露于氧化性氯化物溶液时的耐缝隙腐蚀性能进行评级的方法。 本文件允许通过缝隙腐蚀的化学引发来测量管/棒型样品的临界缝隙温度，该温度等于由相同材料制成的板型样品的临界缝隙温度，但不允许通过电化学方法测量管道中引发的缝隙腐蚀的温度和使用圆柱形样本的管。 该方法也被证明适用于板状试样。 [外文原描述]： ISO 19280:2017 specifies a methodology for ranking the crevice corrosion resistance of stainless steels and related alloys when exposed to oxidizing chloride solution. This document allows the measurement of critical crevice temperatures of tube/rod type specimens equal to those of plate type ones made up of the same material by chemical initiation of crevice corrosion, but not by the electrochemical method of ISO 18070. The test method in this document defines the apparatus and the procedure used to measure the temperature of crevice corrosion initiated in pipes and tubes using cylindrical specimens. This method has also been proved to apply to plate type specimens.
