American Society for Testing and Materials (ASTM)

Society of Automotive Engineers (SAE)

Institute of Electrical and Electronics Engineers (IEEE)

Underwriters Laboratory (UL)

Other organizations promulgate standards or recommended practices that are not accredited by ANSI and are not American National Standards. Such organizations include the Institute of Noise Control Engineering, the Audio Engineering Society (AES), and others, including trade associations.

Role of U.S. Technical Advisory Groups

The ASA also administers nine U.S. Technical Advisory Groups (U.S. TAGs). These U.S TAGs review international documents—primarily draft standards—and develop the U.S. position on them. They also provide the pool of candidates for appointment to international working groups and volunteers to coordinate and prepare draft U.S. positions ( The TAGs are also ANSI-accredited. The nine TAGs are:

  • U.S. TAG for ISO/TC 43, Acoustics

  • U.S. TAG for ISO/TC 43/SC 1, Noise

  • U.S. TAG for ISO/TC 108, Mechanical vibration, shock, and condition monitoring

  • U.S. TAG for ISO/TC 108/SC 2, Measurement and evaluation of mechanical vibration and shock as applied to machines, vehicles, and structures

  • U.S. TAG for ISO/TC 108/SC 3, Use and calibration of vibration and shock measuring instruments

  • U.S. TAG for ISO/TC 108/SC 4, Human exposure to mechanical vibration and shock

  • U.S. TAG for ISO/TC 108/SC 5, Condition monitoring and diagnostics of machines

  • U.S. TAG for ISO/TC 108/SC 6, Vibration- and shock-generating systems

  • U.S. TAG for IEC/TC 29, Electroacoustics

As with the S committees, ASA pays a substantial annual fee to ANSI to be allowed to administer the U.S. TAGs in these subject areas. The TAGs are also accredited by ANSI and must follow their accredited operating procedures.
