Scope

Scope: This document specifies a method for measuring the surface plane stress of ferromagnetic materials and components and equipment in the temperature range of -40°C to 70°C using the magnetic Barkhausen noise method, including load stress and residual stress. This document is applicable to the measurement of magnetocrystalline isotropic materials. For magnetocrystalline anisotropic materials, the methods specified in this standard can be referenced, and certain requirements are placed on the uniformity of the material's microstructure. It can be used for regular inspections or long-term monitoring of load stress in equipment such as pressure vessels, power station boilers, bridges, railways, and steel ropes, as well as for measuring residual stress generated on the surface of components during manufacturing processes, such as cutting, shot peening, casting, forging, cold drawing, heat treatment, and welding.
