Requirements for the content depth and format of engineering standards, regulations and instructions HG/T20703.6-2000
Subject content and scope of application
This standard specifies the content, depth and file format of engineering standards, regulations and instructions (hereinafter referred to as engineering standards) related to materials. This is a specific provision for materials with special requirements in the engineering material selection regulations, and is applicable to design quality management.
2 Basis and purpose of engineering standard compilation
2.0.1 The compilation of engineering standards is based on the engineering material selection regulations and the standards or technical conditions of relevant materials, and is compiled by the material professional. Materials specified by patent holders must also be reviewed and approved by them. 2.0.2 Engineering standards are a supplement and improvement to design standards. The purpose of compilation is to guide material suppliers and manufacturers (or construction units) to manufacture or construct equipment (materials) to ensure the quality of manufacturing and construction. The specific functions and purposes are as follows:wwW.bzxz.Net
Sent to relevant professionals as the basis or component of the compilation of procurement (inquiry) documents. Sent to users to explain the quality requirements of the relevant materials provided in the engineering project. Sent to the relevant manufacturers (or construction units) to explain the procurement requirements for materials as a standard for ordering materials; also explain the requirements for manufacturers (or construction units) and require them to be implemented during equipment manufacturing or construction. 2.0.3 The material quality requirements and equipment manufacturing (or construction) requirements specified in the engineering standards shall not be changed arbitrarily. If certain modifications are required for some reasons, they must be approved in writing by the material professionals. 259
Content of engineering standards
The content of engineering standards should include specific requirements for materials, requirements for inspection methods, requirements for inspection reports, requirements for welding materials, requirements for welding process assessment and welder assessment, as well as construction methods and regulations. Depth of engineering standards
In view of the role and purpose of engineering standards, the depth requirements are as follows: explain its scope of application;
Put forward various specific requirements and regulations related to materials; put forward the main procedures and methods for equipment manufacturing (or construction), testing and inspection; put forward specific inspection requirements and acceptance standards. 5 Format of engineering standards
