Title
Standard Practice for Preparation and Use of Direct Tension Stress-Corrosion Test Specimens

ASTM International

Publication Date:
Jun 28, 1985

Scope:

This practice covers procedures for designing, preparing, and using ASTM standard tension test specimens for investigating susceptibility to stress-corrosion cracking. Axially loaded specimens may be stressed quantitatively with equipment for application of either a constant load, constant strain, or with a continuously increasing strain.

Tension test specimens are adaptable for testing a wide variety of product forms as well as parts joined by welding, riveting, or various other methods.

The exposure of specimens in a corrosive environment is treated only briefly because other standards are being prepared to deal with this aspect. Meanwhile, the investigator is referred to Practices G 35, G 36, G 37, and G 44, and to ASTM Special Technical Publication 425 (1).(Footnote 2)

Footnote 2 - The boldface numbers in parentheses refer to the list of references at the end of this practice.
