This standard specifies the test method for the low-cycle fatigue surface crack growth rate of metal materials under cantilever bending loading at room temperature (15^35℃) and atmospheric environment. This standard is suitable for measuring the surface crack growth rate of metal materials and welded joints greater than 10-5mm/c using rectangular load specimens under constant amplitude strain conditions.
