This specification covers the material, design, and performance requirements pertinent to the manufacture of commercial forced-air gas-fired (Style 1) and electric (Style 2) combination ovens capable of baking, roasting, rethermalizing, and atmospheric pressure steaming, including low-temperature and bio-steaming. The combination ovens, which may be furnished half-size (Class A) or full-size (Class B), are commonly available in the following types: Type 1—table or countertop units; Type 2—stand mounted units; and Type 3—floor units / roll-in units.

1.1 This specification covers commercial combination, atmospheric pressure steaming, which includes low or high temperature steaming, baking, roasting, and rethermalizing forced-air electric and gas-fired ovens.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.3 The following safety hazards caveat pertains only to the test methods portion, Section 8, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
