Rubber seals are essential parts in various mechanical equipment, and their quality and safety have an important impact on the performance and life of the equipment. In order to ensure the quality and safety of rubber seals, the state has implemented a production license system for enterprises engaged in the production of rubber seals. This article will introduce the rubber seal production license inspection rules to help you understand the relevant regulations and requirements.
First. Inspection basis
Rubber seals production license inspection rules are based on the relevant national regulations, standards and enterprise quality management system requirements. Among them, the relevant national laws and regulations mainly include the "Regulations of the People's Republic of China on the Administration of Industrial Product Production Licenses"; Standards include industry standards, national standards, etc., such as GB/T 18173-2017 rubber seal products general technical conditions; The enterprise quality management system requirements are the quality management system documents formulated by the enterprise according to its actual situation.
Second. Inspection items
Rubber seals production license inspection projects mainly include raw material inspection, process inspection, finished product inspection three links.
1. Raw material inspection: The raw materials used in rubber seals are inspected, including the chemical composition and physical properties of raw materials, to ensure that raw materials meet the relevant standards and requirements.
2. Process inspection: the semi-finished products are inspected in the production process, including the size, appearance and hardness of the semi-finished products to ensure that the quality of the semi-finished products meets the requirements.
3. Finished product inspection: a comprehensive inspection of the finished product, including the size, appearance, physical properties of the finished product, to ensure that the quality of the finished product meets the relevant standards and requirements.
Third. Test method
Rubber seals production license inspection methods mainly include appearance inspection, size measurement, physical performance testing and so on. Specific methods should be determined according to different product and quality management system requirements.
1. Appearance inspection: Inspect the surface of the product visually or with tools such as magnifying glass to ensure that there are no obvious defects, scratches, bubbles and other problems on the surface of the product.
2. Size measurement: Use measuring tools to measure the size of the product to ensure that the size of the product meets the design requirements and relevant standards.
3. Physical performance test: test the physical properties of the product through experiments, such as hardness, tensile strength, compression permanent deformation, etc., to ensure that the physical properties of the product meet the relevant standards and requirements.
Fourth. Inspection rules
Rubber seals production license inspection rules include the following aspects:
1. Sampling rules: According to the product type and quality management system requirements, formulate a reasonable sampling plan, determine the sampling quantity and sampling method.
2. Decision rules: According to the test results and relevant standards, the product is judged. If one of the indicators is unqualified, the product is judged to be unqualified.
