National standards refer to the standards approved and issued by the national standardization authority, which are of great significance to the national economic and technological development and are unified throughout the country. National standards are technical requirements that are unified throughout the country, and the standardization administrative department under The State Council shall prepare plans, coordinate the division of labor of projects, organize the formulation (including revision), and uniformly approve, number and issue them.

IS200TRPAH2AHE The duration of the national standard is generally 5 years, after which the national standard is revised or reformulated. In addition, with the development of society, the country needs to formulate new standards to meet the needs of people’s production and life. Therefore, the formulation and revision of national standards is a continuous circular process. Instrument network through the national standard information public service platform search, on March 1, there are four national standards related to instrumentation began to implement.
