This article briefly introduced localization of the old standard SY/T 6476-2000 Drop Weight Tear Test Method of Delivery Pipe and revision background of the new standard of SY/T 6476-2007,compared the above new and old standards with GB/T 8363-2007 The Method for Drop Weight Tear Test of Acicular Steel. The comparison result indicated that in new edition of SY/T 6476-2007, the demand for test equipment, gas medium heating and cooling system and abnormal fracture assessment method of shear area are added. The test methods in SY/T 6476-2007 and GB/T 8363-2007 are basically identical, which all reference to API RP 5L3.
