Accredited Standards Committees
The Acoustical Society of America (ASA) administers four accredited standards committees under contract with the American National Standards Institute (ANSI). See http://www.acosoc.org/standards. The four committees deal with noise and its effects:
-
Accredited Standards Committee S12 Noise,
-
Accredited Standards Committee S1 Acoustics,
-
Accredited Standards Committee S2 Mechanical Vibration and Shock, and
-
Accredited Standards Committee S3 Bioacoustics.
These committees are referred to as accredited standards committees (ASCS) because they are accredited by ANSI and function according to operating procedures approved by ANSI. To maintain their accredited status, the operation of the committees is subject to periodic audits by ANSI. These committees are composed of organizational members who vote on proposed consensus standards; criteria and dues for membership are established by each committee, and balance of interested parties is required. As of November 2008, S12 had 48 organizational members, S1 had 17 organizational members, S2 had 38 organizational members, and S3 had 27 organizational members. Each ASA ASC also has individual experts who assist each committee by providing technical expertise.
ASC S12 Scope: Standards, specifications, and terminology in the field of acoustical noise pertaining to methods of measurement, evaluation, and control, including biological safety, tolerance and comfort, and physical acoustics as related to environmental and occupational noise.
ASC S1 Scope: Standards, specifications, methods of measurement and test, and terminology in the field of physical acoustics, including architectural acoustics, electroacoustics, sonics and ultrasonics, and underwater sound, but excluding those aspects which pertain to biological safety, tolerance, and comfort.
ASC S2 Scope: Standards, specification, methods of measurement and test, and terminology in the field of mechanical vibration and shock, and condition monitoring and diagnostics of machines, including the effects of exposure to mechanical vibration and shock on humans, including those aspects which pertain to biological safety and tolerance and comfort.
ASC S3 Scope: Standards, specifications, methods of measurement and test, and terminology in the fields of psychological and physiological acoustics, including aspects of general acoustics, which pertain to biological safety and tolerance and comfort.
ASA pays a substantial annual fee to ANSI to be allowed to administer these committees. The ASA does this as a public service in furtherance of its mission to “increase and diffuse the knowledge of acoustics and promote its practical application.”
Other organizations have ANSI-approved accredited standards committees that deal with noise; some of their standards are listed below. Many of these standards rely on basic acoustic or noise standards developed by ASA ASC S1, S12, S2, and S3.
Association of Home Appliance Manufacturers (AHAM)
Air Movement and Control Association International, Inc. (AMCA)
Air-Conditioning and Refrigeration Institute (ARI)
Alliance for Telecommunication Industry Solutions (ATIS)
American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE)
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 (http://www.acosoc.org/standards/). 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.
