1 Scope This standard specifies the basic requirements and main operation procedures for the alloying component inspection for the metal members (including welding joint, welding material) of electrical power equipments with spectrum analysis method. This standard is applicable to the spectrum analysis of the alloying component re-inspection and discrimination for all the metal members (including welding joint and welding material) when the electrical power equipments are manufactured, installed and overhauled as well as the re-inspection and discrimination of the alloying component for metallic materials in relevant industries. 2 Normative References The following documents contain provisions which, through reference in this text, constitute provisions of this standard. For dated reference, subsequent amendments (excluding amending error in the text) to, or revisions of, any of these publications do not be applied. However, the parties whose enter into agreement according to these specifications are encouraged to research whether the latest editions of these references are applied or not.
