Why Participate?

ANSI/IICRC Standards are voluntary consensus based standards that are accepted as the standard of care in the industry. Those who participate have a vote on the Standard and can influence what is included and what is not. Participation gives you a voice in the development of the Standard.

Note: BSR is the ANSI Board of Standards Review that reviews and approves Standards as American National Standards. All new Standards under development are designated as BSR/IICRC till such time that they receive final approval from ANSI and can be published.
