This proposal specifies a method for performing the secondary work embrittlement test and the determination of Secondary Work Embrittlement Temperature (SWET) of flat products (sheet and strip) made of metallic materials. The above flat products that are usually used for deep drawing or stamping into components have the thickness from 0.45 mm to 2.50 mm. The test includes the preparation of cup samples with specific geometric sizes by deep drawing process. Then, these cup samples are cooled at various low temperature and impacted by using drop-weight test equipment (with 98J capacity, initial impact energy 98J for steel materials and 49J for Al-Mg light alloys respectively). The highest temperature at which no less than 2 cups of the total 8 cups fracture in a brittle manner is determined as Secondary Work Embrittlement Temperature, SWET.
