ASPE/ANSI 45-2013 Receives ANSI Approval

Chicago — The American Society of Plumbing Engineers (ASPE) announced that the American National Standards Institute (ANSI) has approved ASPE/ANSI 45-2013: Siphonic Roof Drainage as an American National Standard.

 ASPE became an ANSI-accredited standards developer in May 2012, and its first initiative was submitting ASPE 45, originally published in 2007, for approval as an American National Standard. The Working Group headed by Chair Peter Kraut, PE, utilized ASPE’s ANSI-accredited standards development procedures and public review to thoroughly revise the standard for publication.

“The group worked tirelessly for more than a year, discussing and debating the best practices from our collective experiences. We had representation from engineering, manufacturing, and contracting as well as professionals involved in other national standards,” says Peter, who is President of South Coast Engineering Group Inc. in Calabasas, California. “The final product is an exemplary standard that clearly defines the way siphonic roof drainage should be designed. I am extremely proud of the Working Group, ASPE’s Main Design Standards Committee, and all of the volunteers and staff at ASPE who made this happen.”

This new American National Standard establishes the minimum performance specifications for siphonic roof drainage systems and is intended to provide designers, installers, and code officials with a standard of practice for the proper application of siphonic roof drainage. ASPE/ANSI 45 applies to engineered siphonic roof drainage systems intended to prime and operate full-bore through proper pipe dimensioning and the use of siphonic roof drains. It does not apply to conventional roof drains covered under ANSI/ASME A112.6.4, atmospheric roof drainage systems, or sanitary drainage systems.

“ASPE is committed to developing design standards for the construction industry to help ensure the consistent engineering and installation of safe, water-efficient, and energy-conserving plumbing systems,” says ASPE Executive Director/CEO Jim Kendzel, MPH, CAE. “ASPE/ANSI 45 is just the first of many American National Standards ASPE plans to develop for our members and the plumbing engineering industry at large.”
