1 Scope This standard specifies the requirements for temperature measurement of heat treatment, including the requirements for classification of heat treatment equipment and instrument systems, system accuracy tests, temperature uniformity survey, temperature sensor, instruments, management and other aspects. This standard is applicable to the heat treatment of such parts and materials with high requirement, and is not applicable to simple heating and the intermediate heat treatment during production process of materials. Other hot processing technologies may also refer to this standard. 2 Normative References The following documents for the application of this document are essential. Any dated reference, just dated edition applies to this document. For undated references, the latest edition (including any amendments) applies to this document.
