  • SCOPE

    1 Scope

    1.1 These requirements cover motor operated household and commercial disposers rated 600 V or less and intended to be used in accordance with the National Electrical Code, ANSI/NFPA 70. These disposers are intended to convert organic types of waste material to a form that can be accommodated by plumbing systems. The requirements also cover field-installed control assemblies and accessories specifically intended for use with disposers covered by this standard.

    1.1.1 These requirements also cover rechargeable battery-powered appliances with rechargeable non-user-replaceable and/or user-replaceable batteries; see Supplement sc.

    1.2 These requirements do not cover an incinerator-type disposer or a disposer using a universal motor with a rating greater than 250 V.
