Draft Scope/Description:

1 Scope

This standard specifies material, design, construction and performance criteria for the testing and rating of grease interceptors equipped with an automatic grease removal device (GRD).

1.1 Inclusions

This standard applies to grease removal devices designed to automatically remove free-floating grease, fats, and oils from sanitary discharges without intervention from the user except for maintenance.

1.2 Exclusions

This standard does not apply to interceptors intended for rainwater, sanitary wastewater, or wastewater containing petroleum products such as gasoline, heating oils, or mineral oils.

1.3 Terminology

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1.4 Units of measure

The values given in either SI (metric) or U.S. Customary units of measure are equivalent in application; however, each measurement system is to be used independently of the other.  In this Standard, U.S. Customary units are shown in parentheses.  Combining values from the two measurement systems can result in non-conformance with this Standard.

1.4.1 U.S. Customary units

All references to gallons are to U.S. liquid gallons.

1.5 Alternatives

The requirements of this Standard are not intended to prevent the use of alternative designs, materials, or methods of construction, provided such alternatives meet the intent and requirements of this Standard.
