Chapter 1 General Provisions
Article 1.0.1 In order to implement the national technical and economic policies in the reliability appraisal of industrial plants, to achieve advanced technology, economic rationality, safety and applicability, and ensure quality. This standard is formulated to provide unified procedures and criteria for the reliability appraisal of existing industrial plants. Article 1.0.2 This standard applies to the reliability appraisal of the following completed industrial plants:
1. The overall plant, section or component of a single-story or multi-story industrial plant with concrete structure or masonry structure as the main body.
2. The overall plant, section or component of a single-story plant with steel structure as the main body. Article 1.0.3 In addition to implementing this standard, the reliability appraisal of industrial plants in special areas or special environments shall also comply with the provisions of the relevant current national standards and specifications. The reliability appraisal of industrial plants in earthquake zones should be combined with earthquake resistance appraisal. Engineering Construction Standard Full Text Information System

V. Inspection of the structural function and building structure of industrial plants. Article 2.1.5 The reliability appraisal rating of industrial plants shall be divided into three levels: sub-items, projects or combined projects, and assessment units, and each level shall be divided into four levels. And it shall comply with the provisions of Table 2.1.5.
Article 2.1.6 The appraisal report shall include the following contents: 1. Overview of industrial plants;
2. Purpose, scope and content of appraisal; 3. Results of inspection, analysis and appraisal; 4. Conclusions and suggestions;

Section 2 Appraisal Level Standards
Section 2.2.1. The sub-items, projects or combined projects and assessment units of the reliability appraisal of industrial plants shall be rated according to the following provisions: 1. Sub-items
Grade meets the requirements of the current national standards and specifications, is safe and applicable, and no measures need to be taken;
Grade 6 is slightly lower than the requirements of the current national standards and specifications, is basically safe and applicable, and no measures need to be taken;
Grade C does not meet the requirements of the current national standards and specifications, affects safety or affects normal use, and measures should be taken;
Grade D seriously does not meet the requirements of the current national standards and specifications, endangers safety or cannot be used normally, and measures must be taken;
2. Projects or combined projects
The sub-items should be divided into two categories: main sub-items and secondary sub-items according to the different degrees of influence on the reliability of the project. The bearing capacity of the structure, structural connection, etc. should be divided into main sub-items; cracks and deformations of the structure should be divided into secondary sub-items. The main sub-items of Class A meet the requirements of the current national standards and specifications; the secondary sub-items are slightly lower than the requirements of the current national standards and specifications. Normal use, no measures are required; Class B main sub-items meet or slightly lower than the requirements of the current national standards and specifications, and some engineering construction standard full-text information system

minor sub-items do not meet the requirements of the current national standards and specifications. It can still be used normally, and appropriate measures should be taken; Class C main sub-items are slightly lower than or do not meet the requirements of the current national standards and specifications, and appropriate measures should be taken; Some minor sub-items may seriously not meet the requirements of the current national standards and specifications, and measures should be taken; Class D main sub-items seriously do not meet the requirements of the current national standards and specifications, and measures must be taken. The assessment level of the combined project shall be carried out in accordance with the relevant provisions of Chapters 4, 5, and 6 of this standard.
