Standards cover roof drains and stormwater management.

Press Release Summary:



ASME A112.6.9-2005 (R2015), Siphonic Roof Drains, provides guidelines for proper design, installation, examination, and testing of siphonic roof drains, and includes definitions of related terms and parameters. CSA B184 Series-2011 (R2015), Polymeric subsurface stormwater management structures, covers apparatus and accessories used in collection, detention, retention, and infiltration of stormwater runoff. Both ASME and CSA are ANSI accredited standards developers and organizational members.



Original Press Release:



Voluntary Standards Cover the Spectrum: from Roof Drains to Stormwater Management Structures



In an effort to communicate the vital role that standards play in daily life, the American National Standards Institute (ANSI) publishes snapshots of the diverse standards initiatives undertaken in the global and national standards arena, many of which are performed by ANSI members and ANSI-accredited standards developers. Two of the latest selections follow:



Siphonic Roof Drains

Developed in Finland in 1968, siphonic roof drainage is now used globally and in all types of buildings, including industrial, commercial, and retail. Different from conventional drains, a fully engineered siphonic roof drain system prevents air from entering, allowing the pipes to be completely full of water. Preventing air flow protects against debris, and a newly revised standard by the American Society of Mechanical Engineers (ASME) establishes minimum requirements for these systems to avoid failure.



ASME A112.6.9-2005 (R2015), Siphonic Roof Drains, provides guidelines for the proper design, installation, examination, and testing of siphonic roof drains, and includes definitions of related terms and parameters. This American National Standard (ANS) applies to roof drains designed, manufactured, and installed in piping systems that are intended to operate under depressurized siphonic conditions created by the connected piping system.



ASME, an ANSI organizational member and accredited standards developer, is a non-profit professional organization promoting the art, science, and practice of mechanical and multidisciplinary engineering and allied sciences. ASME develops codes and standards that enhance public safety, and enables learning and technical exchange opportunities benefiting the global engineering and technology community.



Stormwater Management Structures

Rain and melting snow contribute to stormwater runoff, which often collects and transports hazardous pollutants as it flows from rooftops, roads, and other soiled areas, especially during stormy seasons. Controlling pollutants through stormwater management structures is increasingly important to stop contamination before it becomes a threat to ecosystems. A recently updated standard published by ANSI member and accredited standards developer CSA Group provides general requirements and methods of testing for polymeric subsurface stormwater management structures.



CSA B184 Series-2011 (R2015), Polymeric subsurface stormwater management structures, covers apparatus and accessories used in the collection, detention, retention, and infiltration of stormwater runoff. Applications include, but are not limited to, commercial, municipal, residential, agricultural, industrial, recreational, and highway drainage.



CSA Group, an ANSI accredited standards developer and organizational member, is a non-profit membership association dedicated to safety, social good, and sustainability through standards development, training, global testing, consumer product evaluation services, and certification services covering industries such as plumbing, construction, medical, safety, technology, appliances, gas, alternative energy, and lighting.
