Indoor Environmental Standards Organization (IESO) Rescinds Portion of 2003 Standard

ROCKVILLE, MD--(Marketwire - January 24, 2011) - In March 2010, the Board of Directors of the Indoor Environmental Standards Organization (IESO) voted unanimously to rescind Section 2 of IESO's Standard of Practice for the Assessment of Indoor Environment Quality, 2nd Edition, 2003. This includes sections 2110 and 2210.

Notice of this action was communicated to known purchasers of the standard last year. However, some people remain unaware this action was taken. IESO is therefore communicating its action to as broad an audience as possible.

IESO became an ANSI accredited standards development organization in 2007. The IESO Standards Development Committee Consensus Body (CB) was created at that time and has full responsibility and authority for creating ANSI standards on behalf of IESO. The CB is presently working on multiple standards, including standards that will ultimately be used in lieu of the 2003 edition of Standard of Practice for the Assessment of Indoor Environment Quality.

Standard of Practice for the Assessment of Indoor Environment Quality was written by an IESO committee in 2002/2003, before IESO became ANSI accredited. The document was not created following ANSI Essential Requirements and other ANSI procedures, and therefore has never been an ANSI-approved standard or the responsibility of the IESO Consensus Body. In rescinding Sections 2210 and 2110, the IESO Board of Directors was acting within its proper authority.
