Application Summary AI generated
This standard specifies the general requirements for conducting small punch tests on metallic materials used in in-service pressure equipment, such as boilers, pressure vessels, and pipelines. It is applied in the petrochemical, power generation, and industrial manufacturing sectors to evaluate material degradation, remaining life, and mechanical properties using miniature specimens extracted from operating components. The method enables non-destructive or minimally invasive assessment of material condition without requiring large sample removal from critical equipment.
