1. Introduction to the ASA Standards Program Paul D. Schomer, Chair ASACOS Susan B. Blaeser, Standards Manager February 2015

2. Why Standardize? Some reasons are obvious - Safety Assure interoperability of parts Benefit from “best in class” information Strive for quality Some are less tangible - Provide basis for government regulation Promote product acceptance Facilitate entry into new markets Level the competitive field

3. Constituent Organizations of the ASA Standards Secretariat

4. 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 needed o Chair, Vice-Chair & Standards Manager Steering Committee – Procedural matters o Executive Committee Members o Chairs of Committees

5. Accredited Standards Committees Operating Under ANSI Procedures S1 - Acoustics S2 - Mechanical Vibration and Shock S3 - Bioacoustics o S3/SC 1 Animal Bioacoustics S12 - Noise

6. S1, Acoustics Acoustical terminology Sound level meters Microphones Acoustical calibrators Filters Physical sound measurements Noise dosimeters Surface impedance measurement

7. 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

8. S3, Bioacoustics Hearing aid specifications Audiometry Speech interference levels Articulation index Threshold of hearing-- Audiometric Zero Calculation of loudness levels

9. S3/SC 1, Animal Bioacoustics Effects of sound on animals (aquatic and terrestrial) Instrumentation Weighting Terminology

10. 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

11. 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.

12. 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 diagnostics of machine systems

13. 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 year o For each ISO/IEC ballot a “coordinator” is appointed o Comments solicited from TAG members & others o Coordinated comments and vote submitted through ANSI (USNC in IEC)

14. Relationship of the Accredited Standards Committees and TAGs

15. 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

16. Primary Deliverables ANSI Approved Documents o American National Standards o Nationally Adopted International Standards Technical Reports can be registered with ANSI ISO/IEC Deliverables o ISO/IEC Standards o Technical Reports o Technical Specifications o Publically Available Specifications o International Workshop Agreements

17. Standards Committee & Subcommittee Membership Voting Organizational Members o Companies o Societies, Trade Assoc. o Government agencies Non-voting o Individual Experts o Working Group Chairs Working Group Members o Ad hoc Groups o Advisory Groups o Liaison Groups, e.g., SAE, ASTM Public Commenters can also provide input

18. ANSI Standards Development Process New Work Effort o Proposal o Ballot Approval o Allocate to existing or new WG Working Group o Develop Draft Document Committee o Ballot by S-Committee o Try to Reverse Negative Votes or Positions Adopt 30-day review Re-ballot a substantially new document o Public review and comment o Develop Consensus--Much more than a plurality usually ~90 % o 5-year Review and Reaffirmation

19. ISO & IEC Standards Development Process New Work Effort o Proposal o Ballot Approval-- TAG Vote o Allocate to existing or new WG Working Group o Working Draft o Develop Committee Draft (CD-1, CD-2, etc.) – now optional Committee o Ballot by TC or SC’s member bodies to become a Draft International Standard (DIS in ISO – CDV in IEC)--TAG Vote ISO Membership o Ballot DIS to become Final DIS-- TAG Vote o Ballot FDIS to become a Standard-- TAG Vote 67% of P-members voting; 75 % of votes o 5-year Review and confirmation

20. Summary National Standard (ANSI) o Ballot to the S-Committee (or Subcommittee) Members o Input from WG Chairs, Individual Experts o 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

21. Result Impact of National and International Standards o Health and safety – e.g. Speech Interference o Public good – e.g. Classroom Acoustics o Measurement – e.g. Sound Power o Instruments – e.g., Sound Level Meter o Calibrations – e.g., Accelerometers o Trade
