The relationship between national standards and industry standards

Generally speaking, national standards have a higher level, but usually both need to be met simultaneously

In terms of the classification of standard specifications, national standards are certainly the highest. However, in terms of the level of requirements, national standards can be regarded as the minimum requirements; thus, many national standards are mandatory standards that represent the basic requirements that must be met. Industry standards are highly specific; if you work in a particular industry, then the standards of that industry are naturally the basic requirements that you need to follow! Now, one hopes to have a basis for everything done. If you can’t find the standards for your industry, those from other industries can serve as a reference. There’s no need to worry; the fact that it’s possible to find standards is in itself a meaningful thing. Legal provisions also emphasize that it is necessary to meet the requirements of **standards and industry standards**

For industries with industry standards as a reference, those standards require greater accuracy.

Industry standards can only be stricter than national standards
