Introduction to the ASA Standards Program

February 2015

Why Standardize?Some reasons are obvious -• Safety• Assure interoperability of parts• Benefit from “best in class”

information• Strive for qualitySome are less tangible - • Provide basis for government

regulation• Promote product acceptance• Facilitate entry into new markets• Level the competitive field

Constituent Organizations of the ASA Standards Secretariat

ASACOS

Acoustical Society of America Committee on

Standards• ASACOS – Policy, finances and program oversight

o Representative of each ASA Technical Committee o Chairs & Vice Chairs of Standards Committees o Ex Officio representatives from ASA, TAGs, etc.o Acts on behalf of ASA and makes recommendations to the Executive

Council

• Executive Committee – Acts for ASACOS when quick action is neededo Chair, Vice-Chair & Standards Manager

• Steering Committee – Procedural matterso Executive Committee Memberso Chairs of Committees

Accredited Standards Committees

Operating

Under ANSI Procedures

• S1 - Acoustics• S2 - Mechanical

Vibration and Shock

• S3 - Bioacoustics oS3/SC 1 Animal

Bioacoustics• S12 - Noise

S1, Acoustics

• Acoustical terminology• Sound level meters• Microphones• Acoustical calibrators• Filters• Physical sound measurements• Noise dosimeters• Surface impedance measurement

S2, Mechanical Vibration and

Shock• Calibration of shock

and vibration transducers

• Characteristics of resilient mounting

• Mechanical vibration of rotating machines

• Human exposure to vibration

• Ship vibration

S3, Bioacoustics• Hearing aid

specifications• Audiometry• Speech interference

levels• Articulation index• Threshold of

hearing--Audiometric Zero

• Calculation of loudness levels

S3/SC 1, Animal Bioacoustics• Effects of sound on

animals (aquatic and terrestrial)

• Instrumentation• Weighting• Terminology

S12, Noise

• Liaison Groups (e.g., SAE, ASTM)o motor vehicles, aircraft,

construction equipment, power tools

• Environmental noise measurement and assessment

• Sound power measurement

• Hearing conservation• Factory noise

measurement• Noise from ships

U.S. Technical Advisory Groups to

ISO/IEC Committees (U.S. TAGs)• IEC/TC29

Electroacoustics

• ISO/TC 43 Acoustics• ISO/TC 43/SC 1 Noise• ISO/TC 43/SC 3

Underwater acoustics

TAGs to IEC committees operate under USNC approved procedures.

TAGs to ISO committees are accredited by ANSI.

U.S. Technical Advisory Groups to

ISO/IEC Committees (continued)• ISO/TC 108 Mechanical vibration, shock and

condition monitoring o SC 2 Measurement and evaluation of

mechanical vibration and shock as applied to machines, vehicles and structures

o SC 3 Use and calibration of vibration and shock measuring instruments

o SC 4 Human exposure to mechanical vibration and shock

o SC 5 Condition monitoring and diagnosticsof machine systems

U.S. Technical Advisory Groups

• Organizational members• Chair (vice chair or co-chair) • Provides pool of experts who may participate

in ISO/IEC working groups• Establishes U.S. position on ISO/IEC matters

more than 80 times per yearoFor each ISO/IEC ballot a “coordinator” is

appointedoComments solicited from TAG members &

othersoCoordinated comments and vote submitted

through ANSI (USNC in IEC)

Relationship of the Accredited Standards Committees and

TAGs

ISO Secretariats Administered

by ASA• ISO/TC 108 Mechanical vibration, shock and

condition monitoring• ISO/TC 108/SC 5 Condition monitoring and

diagnostics of machine systems• ISO/TC 43/SC 3 Underwater acoustics

Primary Deliverables• ANSI Approved Documents

o American National Standardso Nationally Adopted International

Standards Technical Reports can be

registered with ANSI

• ISO/IEC Deliverableso ISO/IEC Standardso Technical Reportso Technical Specificationso Publically Available Specificationso International Workshop

Agreements

Standards Committee &

Subcommittee MembershipVoting Organizational Members

o Companieso Societies, Trade Assoc.o Government agencies

Non-votingo Individual Expertso Working Group Chairs

• Working Group Memberso Ad hoc Groupso Advisory Groupso Liaison Groups, e.g., SAE, ASTM

Public Commenters can also provide input

ANSI Standards Development Process

• New Work Efforto Proposalo Ballot Approvalo Allocate to existing or new WG

• Working Groupo Develop Draft Document

• Committeeo Ballot by S-Committeeo Try to Reverse Negative Votes or Positions

• Adopt• 30-day review• Re-ballot a substantially new document

o Public review and commento Develop Consensus--Much more than a plurality usually ~90 %o 5-year Review and Reaffirmation

ISO & IEC Standards Development Process

• New Work Efforto Proposalo Ballot Approval-- TAG Vote o Allocate to existing or new WG

• Working Group o Working Drafto Develop Committee Draft (CD-1, CD-2, etc.) – now optional

• Committeeo Ballot by TC or SC’s member bodies to become a

Draft International Standard (DIS in ISO – CDV in IEC)--TAG Vote

• ISO Membershipo Ballot DIS to become Final DIS-- TAG Vote o Ballot FDIS to become a Standard-- TAG Vote

• 67% of P-members voting; 75 % of voteso 5-year Review and confirmation

Summary• National Standard (ANSI)

o Ballot to the S-Committee (or Subcommittee) Memberso Input from WG Chairs, Individual Expertso Public comment

• International Standard (ISO/IEC)o Ballot to the TAG (determines U.S. position)

• TAG Members• Liaison Groups• USA Document Coordinator• TAG Chair • Other stakeholders

Result• Impact of National and International

Standardso Health and safety – e.g. Speech Interferenceo Public good – e.g. Classroom Acoustics o Measurement – e.g. Sound Powero Instruments – e.g., Sound Level Metero Calibrations – e.g., Accelerometerso Trade
