Introduction to the ASA Standards Program
Paul D. Schomer, Chair ASACOSSusan B. Blaeser, Standards Manager
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
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)
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
