The American National Standards Institute (ANSI) is looking for public comments relating to fire doors.
ANSI, which oversees the creation, circulation and use of thousands of guidelines in several industries, is considering several proposals sponsored by the National Fire Protection Association (NFPA).
Proposal BSR/NFPA 252-201x, Standard Methods of Fire Tests of Door Assemblies is a revision of ANSI/NFPA 252-2007. The revision prescribes standardized fire and hose stream test procedures that apply to fire-door assemblies intended to be used to retard the spread of fire through door openings in fire-resistive walls.
All comments must be received by March 4, and will be included in the semi-annual NFPA Report on Comments. Comments and proposals can be submitted online to NFPA’s website.
The revision can be reviewed on the ANSI website, www.ansi.org.
