ASSE International publishes revised performance requirements for plumbing aspects of residential food waste disposer units

Mokena, Ill. (June 7, 2019) — ASSE 1008-2019, Performance Requirements for Plumbing Aspects of Residential Food Waste Disposer Units, has been designated as an American National Standard by the American National Standards Institute (ANSI) and is now available for purchase.

ASSE 1008 applies to the plumbing aspects of residential food waste disposers, which are primarily installed in residential kitchen sink outlets. These devices are designed to reduce food waste particle sizes for discharging into sanitary drainage systems. This standard provides a basis for evaluating the adequacy of appliance design and performance to ensure sanitary conditions and to protect the public from health hazards that could result from improper design or manufacture.

“The performance criteria of ASSE 1008 are based on broad field experience and extensive engineering research on the protection of the potable water supply and safe discharge of wastes into the sanitary plumbing system,” said David Hoyer, ASSE 1008 Working Group Chairperson and Senior Regulatory Engineer for InSinkErator. “Engineers and technicians representing manufacturers, public health officials, plumbing contractors, inspection agencies, and plumbing testing laboratories contributed the technical expertise and experience necessary to develop a meaningful and scientifically sound evaluation method that takes into account conditions that could adversely affect the sanitary performance of these appliances.”

Performance requirements in ASSE 1008 include compliance testing for thermal cycling and conditioning, dishwasher discharge, particle size retention, self cleaning, flooding, mechanical shock protection, and detailed requirements for installation and maintenance instructions.

To purchase ASSE 1008-2019, please visit the ASSE International Webstore at For questions regarding the standard, contact Staff Engineering Supervisor Conrad Jahrling at or (708) 995-3017.
