What's the difference between national standard and non standard stamping parts?

  • 2022-02-23

The quality standards of stamping parts are divided into national standard and non-standard. The following are different concepts about national standard and non-standard:

National standard: refers to the standard approved and issued by the national standardization authority, which is of great significance to the national economic and Technological Development and is unified throughout the country. National standards are unified technical requirements throughout the country. It is composed of national standards, but it is not enforced. GB / T ****** GB stands for national standard, and t stands for recommendation, that is, national recommended standard.
Non standard: it is not manufactured according to the unified industrial standards and Specifications issued by the state, but designed and manufactured according to its own needs. The specification, size, mechanical properties and material of fasteners shall be determined by the user. According to the user's actual use, make standard parts according to the drawings.

So what is the difference between the national standard and non marking of stamping parts?

Standard parts are produced according to the specifications and standards stipulated by the state and approved by the standards; Non standard parts are normally produced in accordance with national standards, but they have not passed the inspection and certification, and some are produced in accordance with industry standards or enterprise standards. In fact, there is no big difference on the whole, but the specification of standard parts is more accurate. As for the quality, it depends on the enterprise standard. It is not necessarily that the national standard parts are better than the non-standard parts!!! It should be analyzed in detail!!!
