What is ANSI?

The American National Standards Institute is a non-profit private standardization group. But it has actually become the national standardization center; all standardization activities in various fields are carried out around it. Through it, the relevant government systems and private systems cooperate with each other, playing the role of a bridge between the federal government and the private standardization system. It coordinates and guides national standardization activities, provides assistance to standard formulation, research and use units, and provides domestic and foreign standardization information. It also plays the role of an administrative agency.

Staff of the National Bureau of Standards (NBS) and official representatives of many other agencies of the U.S. government also participate in the work of the American Standards Institute through various channels.

The American Standards Institute has various technical committees such as electrical engineering, construction, daily necessities, drawing, and material testing.

The American National Standards Institute itself rarely formulates standards. The compilation of its ANSI standards mainly adopts the following three methods:

1. The relevant units are responsible for drafting, inviting experts or professional groups to vote, and the results are reported to the Standard Review Committee established by ANSI for review and approval. This method is called the voting survey method.

2. The technical committees of ANSI and representatives of the committees organized by other institutions draft the draft standards, all members vote, and finally the Standard Review Committee reviews and approves them. This method is called the committee method.

3. From the standards formulated by various professional societies and associations, the more mature ones that are generally important to the country are reviewed by the ANSI technical committees and promoted to national standards (ANSI) and given the ANSI standard code and classification number, but the original professional standard code is retained at the same time.

The vast majority of the standards of the American National Standards Institute come from various professional standards. On the other hand, various professional societies and associations can also formulate certain product standards based on existing national standards. Of course, they can also formulate their own association standards without following national standards.

ANSI standards are adopted voluntarily. The United States believes that mandatory standards may limit productivity improvements. However, standards cited by laws and formulated by government departments are generally mandatory standards.
