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.
