THE ACOUSTICAL SOCIETY OF AMERICA STANDARDS
PROGRAM

• Paul D. Schomer, Chair ASACOS
• Susan Blaeser, Standards Manager
• Updated Nov. 2007

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

  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)

• 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
