Standard Specification for Kettles, Steam-Jacketed, 32 oz to 20 gal (1 to 75.7 L), Tilting, Table Mounted, Direct Steam, Gas and Electric Heated
ABSTRACT
This specification covers jacketed kettles using steam as a source of heat for cooking food in commercial and institutional food service establishments. However, it does not cover equipment used by food processors. Covered by this specification are jacketed kettles of various sizes (capacities), grades (Grades 1-3 based on maximum working pressure), styles (Styles 1-5 according to mounting configuration), and classes (Classes A-D based on steam source, whether direct steam or gas-fired or electric steam generator). Kettle and steam jacket shall be manufactured from Type 304, 304L, 316, or 316L corrosion resistant steel. All exterior surfaces of Styles 3-5 kettle stands and bases shall be made of Type 302, 304, 316, or 430 corrosion resistant steel, while those of the kettle mount or support base shall be chrome plated or made of Type 304, 316, or 430 corrosion resistant steel such as for exterior surfaces of console and base of Class B and C kettles. As specified, the kettles shall be provided with the following components: insulation casing, covers and/or operating handles, safety relief valve, swing spout water supply, basket insert, tilt mechanism (hand or crank tilt), kettle mount or support base, control box, safety cut-off, and thermostat. The kettle shall be tested for capacity, heating time, and energy utilization, and shall conform to the requirements specified.
SCOPE
1.1 This specification covers jacketed kettles that use steam as a heat source for cooking food in commercial and institutional food service establishments. This specification does not cover equipment used by food processors who normally package the food that they cook.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 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.
