Specifies design, constructional, plumbing and performance requirements as well as requirements for markings, installation and operational instructions and detailed tests. An appendix gives recommendations for installation of disposal units to minimize noise.

This standard specifics requirements for food waste disposal units for household use, intended to be permanently fitted in the outlet of a sink and in which the food waste is shredded by mechanical action into pieces and flushed down a household drain. It applies only to those units intended to be connected to a single-phase a.c. supply at voltages not exceeding 250 V.NOTE: Food waste includes all perishable food waste but does not include packaging materials such at cans and bottles.
