Application Summary AI generated
This standard specifies a small punch test method for evaluating the tensile properties of metallic materials used in in-service pressure equipment at room temperature. It is applied to assess material degradation, such as embrittlement or strength loss, in components like boilers, pipelines, and pressure vessels where only very small material samples can be extracted. The method enables non-destructive or minimally invasive testing to determine yield strength and tensile strength, supporting safety assessments and remaining life evaluations of aging equipment.
