General Rules for Quality Grading of Rubber Machinery Products
HG/T2395-92
In order to scientifically analyze and evaluate the product quality level and strengthen the macro-guidance of quality management, it is necessary to establish an indicator system for macro-evaluation of product quality. The product quality grade rate is the leading indicator of the indicator system and a comprehensive reflection of the product quality level. The product quality grading standard is the assessment basis of this indicator, and it is a unified regulation and basis for correctly and completely measuring and assessing the quality grade level of enterprise products. In order to standardize the formulation of the quality grading standard for rubber machinery products, this general rule is specially formulated. 1 Subject content and scope of application
This general rule stipulates the principles for the classification of rubber machinery product quality grades, the content of assessment, and the principles and methods for evaluation. This general rule is applicable to the main products of rubber machinery and is the basis for the compilation of quality classification and inspection details of various types of main rubber machinery products. 2 Reference standards
GB1.1 Guidelines for standardization work Basic provisions for the compilation of standards GB1.2 Guidelines for standardization work Standards for publication and printing GB1.3 Guidelines for standardization work Provisions for the compilation of product standards 3 Principles for the classification of product quality grades
The product quality level is divided into three levels: superior products, first-class products and qualified products. 3.1 Superior products
3.1.1 The main quality indicators of the product, such as structure, performance, accuracy, reliability and life, safety, hygiene, and economy, must meet the standards of the international advanced level, and the physical quality level must reach the advanced level in the past five years compared with similar foreign products. 3.1.2 The quality of the product production process is stable.
3.1.3 The main accessories and supporting products can ensure that the host reaches the level of first-class products. 3.1.4 Users evaluate that the product quality is equivalent to the advanced level of similar international products. The product is competitive in the international market. 3.2 First-class products
3.2.1 The main quality indicators of the product such as structure, performance, accuracy, reliability and life, safety, hygiene, economy, etc. must meet the standards of the general international level, and the physical quality level reaches the general level of similar international products. 3.2.2 The quality of the product production process is stable.
3.2.3 The main accessories and supporting products can ensure that the host reaches the level of first-class products. 3.2.4 Users evaluate that the product has a good use effect. The product is competitive in the domestic market. 3.3 Qualified products
3.3.1 The main quality indicators of the product such as structure, performance, accuracy, reliability and life, safety, hygiene, economy, etc. fully meet the requirements of the current standards. The products are produced according to the current standards of my country (national standards, industry standards, local standards or enterprise standards), and the physical quality level must meet the requirements of the above corresponding standards. 3.3.2 The quality of the product production process is stable
3.3.3 The main accessories and supporting products can ensure that the main machine reaches the qualified product level, 3.3.4 Users evaluate that the product can meet the use requirements, and the Ministry of Chemical Industry of the People's Republic of China approved the standard on September 15, 1992. m.b2soso.cem various standards industry information free download 1993-07-01 implementation
