Detailed Rules for Review of Design Documents of Material Specialty
HG/T20703.7-2000
Subject Content and Scope of ApplicationwwW.bzxz.Net
This standard specifies the basic contents of review of design documents such as the engineering material selection regulations compiled by the material specialty and the engineering standards, regulations and instructions related to materials, and is applicable to design quality assurance work. 2 Detailed Rules for Self-Review and Verification
2.0.1 Verification of Design Document Integrity
Check whether the acceptance conditions are complete, whether they are the latest version, and whether they are signed as required. 1
Check whether the design documents are complete and whether they are written in accordance with the requirements of "Content Depth and Format Requirements for Engineering Material Selection Regulations" and "Content Depth and Format Requirements for Engineering Standards, Regulations and Instructions". 2.0.2 Verification of Engineering Material Selection Regulations
1 Verify whether the design conditions based on which the Engineering Material Selection Regulations are prepared are consistent with the accepted conditions, that is, whether the materials selected for the process equipment are determined according to the design conditions (material composition and characteristics, design pressure, design temperature, operating pressure, operating temperature and material corrosiveness, etc.). 2 Verify whether the specified minimum corrosion margin of the material is reasonable, and whether the necessary restrictions and precautions (such as the restriction requirements on the content of harmful media in the material, etc.) are appropriate. 3 Verify whether the selected materials are explained or specifically stipulated in the Engineering Material Selection Regulations when there are welding, inspection, construction, intergranular corrosion tests and other requirements. 4 Verify whether the selected material grades and requirements meet the relevant material standards or technical conditions (national, industry or enterprise standards). The current latest version of the standards or technical conditions shall prevail. 5 Verify whether the selected special materials meet the requirements. 6 Verify whether all equipment names and position numbers in the Engineering Material Selection Regulations are consistent with the process flow chart, and whether there are omissions and errors.
7 Check whether the project name, project number, device/main item name, design time, edition, etc. are correct. 2.0.3 Check the design documents such as engineering standards, regulations and instructions related to materials. 1 Check whether the basis for preparing the design documents is consistent with the requirements or regulations in the "Regulations on the Selection of Engineering Materials", that is, whether it meets the process requirements for materials.
2 Check whether the relevant materials (including special materials) in the design documents meet the relevant standards and technical conditions, that is, whether the proposed chemical composition, mechanical properties and related inspection and test data and requirements are reasonable. 3
Correct.
Check whether the selected welding materials are reasonable. Check whether the specified welding process assessment and welder skill assessment requirements are reasonable. Check whether the specified intergranular corrosion test methods are reasonable. Check whether the specified construction methods and steps are reasonable. Check whether the specified additional inspection items and acceptance indicators are reasonable. Check whether the specified heat treatment methods are reasonable. Verify whether the project name, project number, device/main item name, design time, edition, design document number, etc. are 3 Audit Rules
In view of the particularity of material specialties, the auditor should not only refer to the audit rules for audit, but also focus on the following contents:
Review whether the materials used in the "Engineering Material Selection Regulations" meet the requirements of process conditions and whether they meet the principles of economy and rationality.
3.0.2 Review whether the use of special materials in the "Engineering Material Selection Regulations" meets the provisions of other relevant material standards.
3.0.3" Review whether the specific provisions and requirements in the engineering standards are feasible. 3.0.4 Review whether the material standards, specifications or technical conditions selected in the design documents are correct and whether they meet the requirements of the company (institute), this project and relevant users. 263
