Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specification covers commercial microw

3、ave ovens.These ovens use ultrahigh frequency electromagnetic radiationin the approved industrial, scientific, and medical bands todefrost, heat, and cook food.1.2 LimitationsThis specification does not include alltypes, sizes, groups, styles, and classes of the commoditiesindicated by the titles of

4、 the specification, or that are commer-cially available, but is intended to cover the types, sizes,groups, styles, and classes that are suitable for general require-ments.1.3 Oven Selection And Application Prior to the use of theclassifications given in 4.1, the user agency should ensure theyare not

5、 restricted by some aspect of the microwave oven designsuch as a weight or external dimension limitation that wouldprevent the unrestricted use of the classifications given in 4.1.1.4 Microwave Oven AvailabilityAlthough 4.1 lists awide range of sizes, classes, groups, and styles for commercialtypes

6、of ovens, not all combinations are available.1.5 The values stated in inch-pound units are to be regardedas the standard. The SI units given in parentheses are forinformation only.1.6 The following precautionary caveat pertains to the testmethod portion only, Section 11, of this specification: Thiss
