Standard and Specification for Fastener Pins
The fastener pin standard is a unified regulation for the development, production and operation of fastener pins and related concepts, and is a technical regulation for the development, production and operation of fastener pins. An extension of the Fastener Pin Standard forms the Fastener Pin Specification. The standards and specifications for fastener pins are the minimum requirements for the development and production of fastener pins.
After a long period of development and improvement, the international and domestic fastener sales standards have formed a relatively complete system.
ISO standards, international industry association standards, regional standards and national standards form 4 relatively independent fastener pin standard systems. The four systems can be divided into general basic standards, management standards, information system standards, product design standards, material standards, process tooling standards, experimental measurement standards, and packaging and transportation standards.
ISO standards and international industry association standards have no mandatory meaning for any country, organization or individual. However, the capital of standard parts emphasizes that from a technical point of view, ISO standards and international industry association standards are relatively advanced standards in the world and should be adopted as much as possible.
The domestic fastener sales standards in various countries are sorted out, including three levels of national standards, industry standards and enterprise standards.
The national standard is the first level, which is a unified regulation on technical requirements nationwide, formulated by the standardization administrative department of the State Council.
The second level of the industry standards committee is a unified regulation on technical requirements within a certain industry, which is formulated by the relevant administrative department of the State Council.
The enterprise standard is the third level, which is a unified regulation of technical requirements within a certain enterprise, which is formulated by the enterprise itself.
The state encourages the formulation of lower-level standards that are stricter than the higher-level standards for matters that have been stipulated by the higher-level standards. The requirements of the subordinate standard shall not be lower than the requirements of the superior standard for the same content
