# 1 THE ACOUSTICAL SOCIETY OF AMERICA STANDARDS PROGRAM Paul D. Schomer, Chair ASACOS & Susan Blaeser, Standards Manager Updated Nov. 2007

# 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

# 10 S12, Noise Environmental noise measurement and assessment Sound power measurement Hearing conservation Factory noise measurement Noise from ships Liaison Groups (e.g., SAE, ASTM) –motor vehicles, aircraft, construction equipment, power tools

# 11 ISO/IEC Technical Advisory Groups (TAGs) Operating Under ANSI Accredited Procedures IEC/TC29 Electroacoustics ISO/TC 43 Acoustics ISO/TC 43/SC 1 Noise Continued on next slide.

# 12 ISO/IEC Technical Advisory Groups (TAGs) Operating Under ANSI Accredited Procedures (con’t.) ISO/TC 108 Mechanical vibration, shock and condition monitoring –SC 2 Measurement and evaluation of mechanical vibration and shock as applied to machines, vehicles and structures –SC 3 Use and calibration of vibration and shock measuring instruments –SC 4 Human exposure to mechanical vibration and shock –SC 5 Condition monitoring and diagnostics of machines –SC 6 Vibration and shock generating 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  For each ISO/IEC ballot a “coordinator” is appointed  Comments solicited from TAG members  Coordinated comments and vote submitted through ANSI (USNC in IEC)

# 14 ISO Secretariats Administered by ASA ISO/TC 108 Mechanical vibration, shock and condition monitoring ISO/TC 108/SC 5 Condition monitoring and diagnostics of machines

# 15 Primary Documents ANSI Approved Documents –American National Standards –Nationally Adopted International Standards –Other, e.g., Technical Reports ISO/IEC Approved Documents –ISO/IEC Standards –Other, e.g., Technical Reports, Technical Specifications

# 16 Standards Committee & Subcommittee Membership Voting Organizational Members Companies Societies, Trade Assoc. Government agencies Non-voting Individual Experts Working Group Chairs Working Group Members Ad hoc Groups Advisory Groups Liaison Groups, e.g., SAE, ASTM

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

# 18 ISO Standards Development Process New Work Effort –Proposal –Ballot Approval-- TAG Vote –Allocate to existing or new WG Working Group –Working Draft –Develop Committee Draft (CD-1, CD-2, etc.)  Ballot by member bodies to become a Draft International Standard (DIS)--TAG Vote Committee –Ballot DIS to become Final DIS-- TAG Vote –Ballot FDIS to become a Standard-- TAG Vote  67% of P-members voting; 75 % of votes 5-year Review and Reaffirmation

# 19 Summary National Standard (ANSI) –Ballot to the S-Committee (or Subcommittee) Members International Standard (ISO/IEC) –Ballot to the TAG (determines U.S. position)  TAG Members  Liaison Groups  USA Representative  USA Document Coordinator  TAG Chair

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