Rubber seals production license inspection rules

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.

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.
