It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The use of contoured crevice formers may be considered in such situations, but the use of a pitting test Practices A, C, or E should be considered. The available pitting and crevice testing methods include:.
Method D — Critical crevice temperature test for nickel-base and chromium-bearing alloys. We follow a standard practice we have developed to minimize these variations and provide consistent data. NOK 1 ,00 excl. Grinding or pickling on stainless steel surfaces may destroy the passive layer. You need to log in before adding standards to the monitoring service.

In many ways, G is ideal for use instead of methods C-F as it is a more rapid method that can be performed within days instead of weeks.
Testing by ASTM G48 for Pitting and Crevice Corrosion
ASTM G 48 is a relatively severe test, but lack of definition in the standard can lead to variation of data. However, the G48 g48-111 is meant for ranking or qualification, and not as designed for determining a corrosion rate over time.
Which one do you need? If you need to be able to add standards to the monitoring service, you must register as a user with your own username and password. There are several factors that can influence the selection of methods; we can help you with this part of the process as well. g48-111

A and B are for qualification of alloys to pitting and crevice corrosion at specific temperatures, C and D are for determining the critical pitting and crevice corrosion temperatures of chromium and nickel alloys, and E and F are for stainless alloys. Methods A and B are designed to cause the breakdown of Type at room temperature. Method Atsm — Critical pitting temperature test for stainless steels.
Method B — Ferric chloride crevice test.
ASTM G48 – 11(2015)
When testing as-welded, cylindrical, or other non-flat samples, the standard crevice formers will not provide uniform contact.
