Corrosion of Metals and Alloys - Stress Corrosion Testing
- Part 4. Preparation and Use of Uniaxially Loaded
Tension Specimens
1 Scope
1.1 This Part of GB/T 15970 covers procedures for designing, preparing and using
uniaxially loaded tension test specimens for investigating the susceptibility of a metal
to stress corrosion.
The term "metal'' as used in this Part of GB/T 15970 includes alloys.
1.2 Tension test specimens are adaptable for testing a wide variety of product forms,
including plate, rod, wire, sheet and tubes, as well as parts joined by welding, riveting,
or other methods. Notched specimens may also be used (see 5.1.3).
1.3 Uniaxially loaded tensile specimens may be stressed quantitatively with equipment
for application of either a constant load, a constant strain or an increasing load or strain.
2 Normative References
