It is adtm to have all the specimens in one? All traces of oxide scale formed during heat treatment must be removed. Each sample must be in a separate cradle so that the samples do not touch. For very heavy sections, specimens should be prepared to represent the appropriate surface while maintaining reasonable specimen size for convenience in testing.

Link to Active This link will always route to the current Active version of the standard. If the document is revised or amended, you will be notified by email. Preparation of Test Specimens For specific safety precautionary statements, see 3. This practices covers the detecting susceptibility to intergranular attack in ferritic stainless steel.

Warning—Protect the eyes and face by face shield and use rubber gloves and apron when handling acid. NOTE 2—Other equivalent means of specimen support such as glass hooks or stirrups may also be used. Already Subscribed to this document. Times longer than 24 h should be included in the test report.

It may also detect the presence of chi or sigma phase in these steels.
