May 23, 2024 · 5.1 This test method provides a prediction of the resistance to stable propagating pitting corrosion of stainless steels and related alloys in a standard medium (see Note 1). The CPT test can be used for product acceptance, alloy …

In all cases only the current version of the standard as published by ASTM is to be considered the official document. This standard is issued under the fixed designation G150; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

According to the ASTM G150, the CPT is defined as the temperature at which the current density exceeds 100 μA/cm2 for one minute. In Figure 1, the current vs. time (blue line) and temperature vs. time (red line) curves are shown.

1.1 This test method covers a procedure for the evaluation of the resistance of stainless steel and related alloys to pitting corrosion based on the concept of the determination of a potential independent critical pitting temperature (CPT).
