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
