As defined in the Standardization Law of the People's Republic of China, standards refer to unified technical requirements in agriculture, industry, services, and social undertakings. Serving as a universal normative language, standards play a vital role in rationally utilizing national resources, ensuring product quality, enhancing market trust, promoting commodity circulation, maintaining fair competition, and safeguarding security. They constitute a crucial technical framework for regulating economic and social development. Particularly with the deepening of economic globalization, standards have become fundamental elements of national core competitiveness. Following product and brand competition, standards competition is emerging as a deeper, higher-level, and more influential form of rivalry.
Typically, the priority sequence for standard selection is: National standards → Industry standards → Local standards → Association standards. National and industry standards take precedence when available. In their absence, associations may independently formulate standards. However, association standards established in the presence of national/industry standards must exceed the latter in requirements; otherwise, they are deemed invalid.
