ASTM-G49 › Standard Practice for Preparation and Use of Direct Tension Stress-Corrosion Test Specimens
Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
1.1 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.
1.2 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.
1.3 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 G35, G36, and G37, and G44, and to ASTM Special Technical Publication 425 (1).
