4 Tensile Test

4.1 General

This Chapter is applicable to tensile test of metals (including base metal, weld metal and welded joint) at room temperature and high-temperature. The temperature range of room-temperature test is generally 10°C~35°C; for test having stringent requirements on temperature, the test temperature shall be 23°C ± 5°C. The temperature of high temperature test shall be greater than 35°C.
