EC-9 Proposal Defeated at IEC Code Committee Meeting

A proposal to use EC-9 to reference AAMA 507 as an alternative to the NFRC 100 site build procedure, for the rating (but not certification) of commercial fenestration products, was defeated by a vote of 11-2 at the IEC Code Committee meeting today.

The meeting was part of the International Code Council code hearings being held in Orlando, Fla.

The American Architectural Manufacturers Association (AAMA) and Insulating Glass Manufacturers Association (IGMA) both supported the proposal, which had been presented by the Glass Association of North America (GANA), the Aluminum Extruders Council (AEC) and Craig Connor.

Those supporting the proposal cited ease of use, output acceptability and providing an alternative for rating (not certification).

Current procedures were initially designed for residential applications and supporters of EC-9 sought an alternative reference designed for use specifically in commercial buildings.

One of three members of the NFRC board of directors sitting on the IEC Code Committee abstained from voting, citing a conflict of interest.
