The main difference between national standards and industry standards is mainly reflected in the definition, order of obedience, use, classification, and formulation of the main body.
First of all, the definition of the national standard is a national technical, management or work requirements, divided into mandatory and recommended, the State Council is responsible for the management and review, review cycle is generally no more than 5 years, the standards do not meet the social development and technological progress will be revised or abolished. In contrast, industry standards are uniform technical requirements within a specific industry, and enterprise standards are the basis for internal management and production, and are only applicable when not covered by national and industry standards.
In the order of obedience, industry standards need to comply with national standards, and enterprise standards need to follow the national standard and industry standards. National standards focus on basic needs such as personal safety and ecological environment, while industry standards focus on the stable operation within the industry, such as pharmaceuticals, food hygiene and other industry standards. Enterprise standards, on the other hand, are based on existing standards, and companies can set stricter standards to improve product quality.
Categorized, the national standards cover three major categories of technology, management and work, with a wide range of scope, while the industry standards and enterprise standards are more focused on specific areas, such as pharmaceuticals, food or industrial and agricultural products. Enterprise standards, depending on the product, can develop product standards, quality enhancement standards or complementary to national and industry standards.
Finally, the main body of the development is different, the national standard is approved by the State Council for release, the industry standard is managed by the industry under the department of management, the enterprise standard is developed by the enterprise itself and approved by the legal representative of the enterprise for release.
Overall, the national standard is the foundation of the national level, the line standard is the specific implementation of the industry, the enterprise standard is to provide customized requirements within the enterprise, the three **** with the same constitute the different levels of China's standardization system.
