Energy performance and capacity measurement of household microwave ovens

1.1
This Standard applies to cord-connected microwave ovens intended for use on nominal 120/240 V branch circuits and microwave ovens intended for permanent connection to branch circuits up to 240 V, manufactured for use in homes and similar locations.

1.2
This Standard specifies methods of testing the energy consumption in both active and standby modes of electrically operated microwave ovens as well as measuring the cavity volume.

1.3
This Standard applies to microwave ovens designed to heat food by use of microwave energy. The forms of microwave ovens include portable, countertop, counter-mounted, stationary, stationary-combination, built-in, and built-in combination, microwave/conventional cook top, microwave/conventional oven, microwave/conventional range, and convection microwave oven.

1.4
The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.

1.5
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.
