ASTM F1602-12(2017)

Standard Specification for Kettles, Steam-Jacketed, 20 to 200 gal (75.7 to 757 L), Floor or Wall Mounted, Direct Steam, Gas and Electric Heated

ABSTRACT
This specification covers the material, design, and performance requirements associated with the construction of non-tilting (Type I) and tilting (Type II) jacketed kettles that use steam as a heat source for cooking food in commercial and institutional food service establishments. The kettles shall be available in four styles as follows: Style 1—floor mounted, pedestal; Style 2—floor mounted, with legs; Style 3—wall mounted; and Style 4—cabinetized. The kettles shall be classified into the following classes: Class A—directly connected to an external heat source; Class B—self-contained, gas-fired steam generator; and Class C—self-contained, electric steam generator. They shall also be grouped into three Grades according to maximum working pressure rating, and ten sizes according to capacity. The products shall be evaluated for their conformance with capacity, heating time, and energy utilization requirements.
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.

3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 jacketed kettle—as used in this specification, a cylindrical, deep-sided vessel (steam jacketed), with either a hemispherical
or sloping bottom of 20 to 200-g (75.7 to 757-L) capacity for cooking food in a liquid. The kettle may be tilting or non-tilting
(stationary cooking jacket).
3.1.1.1 Discussion—
Jacketed kettles may be floor or wall mounted. The energy in the steam moving through the jacket is transferred to the liquid and
to the food by condensation of the steam on the vessel wall.
4. Classification
4.1 Jacketed kettles covered by this specification are classified by type, size (capacity), grade, style, and class.
4.1.1 Type:
4.1.1.1 Type I—Non-tilting.
4.1.1.2 Type II—Tilting.
4.1.2 Size (Capacity):
4.1.2.1 20-gal (75.7-L) capacity,
4.1.2.2 25-gal (94.6-L) capacity,
4.1.2.3 30-gal (113.6-L) capacity,
4.1.2.4 40-gal (151.4-L) capacity,
4.1.2.5 60-gal (227.2-L) capacity,
4.1.2.6 80-gal (302.8-L) capacity,
4.1.2.7 100-gal (378.5-L) capacity,
4.1.2.8 125-gal (472.1-L) capacity,
4.1.2.9 150-gal (567.8-L) capacity, and
4.1.2.10 200-gal (757.0-L) capacity.
4.1.3 Grade:
4.1.3.1 Grade 1—Maximum Working Pressure Rating of 15 to 25 psig (103.4 to 172.4 KPa) or less.
4.1.3.2 Grade 2—Maximum Working Pressure Rating of 26 to 50 psig (179.3 to 344.7 KPa) or less.
4.1.3.3 Grade 3—Maximum Working Pressure Rating of 51 to 90 psig (351.6 to 620.5 KPa) or less.
4.1.4 Style:
4.1.4.1 Style 1—Floor mounted, pedestal.
4.1.4.2 Style 2—Floor mounted, with legs.
4.1.4.3 Style 3—Wall mounted.
4.1.4.4 Style 4—Cabinetized.
4.1.5 Class:
4.1.5.1 Class A—Directly connected to an external heat source.
4.1.5.2 Class B—Self-contained, gas-fired steam generator.
4.1.5.3 Class C—Self-contained, electric steam generator.

6. Materials
6.1 General—Steam jacketed kettles shall conform to the following requirements:
6.2 Kettle—The kettle shall be constructed of type 304, 304L, 316, or 316L corrosion-resistant steel conforming to Specification
A167 or A240/A240M.
6.3 Steam Jacket—The jacket shall be constructed of type 304, 304L, 316, or 316L corrosion-resistant steel.
6.3.1 Class B and Class C Steam Jackets—Jackets shall be fabricated from material conforming to Specification A285/A285M
or Specification A516/A516M material and skirted with type 302 or 304 corrosion-resistant steel conforming to Specification A167
or A240/A240M.

F1602 − 12 (2017)
6.5 Exterior of Style 4 Jacketed Kettles and Class B or Class C Kettles—Unless otherwise specified, material shall be types 302,
304, 316, or 430 corrosion-resistant steel conforming to Specification A240/A240M, A167 or A176, as applicable, and the
thickness shall be 20 gauge [0.0375-in. (1-mm) U.S. revised standard gauge] minimum.
7. Design and Construction
7.1 General—The kettle shall be delivered assembled and ready for connection to steam, water, electricity, or gas piping, as
applicable. The kettles are to be equipped with a suitable drain and exhaust steam termination, if applicable. The height from the
floor to the top rim of the kettle shall not exceed the following: 44 in. (1219 mm) for 20 to 40-gal (75.7 to 151.4-L) kettles and
51 in. (1295 mm) for 60 to 100-gal (227.2 to 378.5-L) kettles. If applicable, the clearance from the floor to the outlet of the draw-off
valve shall be a minimum of 12 in. (304.8 mm).
7.1.1 Jacketed Steam Chamber—The steam containing part of the kettle shall be rated for the following allowable working
pressures (WP):
7.1.1.1 Direct Connected Kettles—minimum 15 psi (103.4 Kpa), and
7.1.1.2 Self-Generating Kettles—minimum 15 psi (103.4 Kpa).
7.1.2 The design and construction of the kettle jacket shall be in accordance with the ASME Boiler and Pressure Vessel Code,
Section VIII, Division 1 with a National Board Registration Number.
7.1.3 Insulation Casing—When insulation is required, it shall be contained in a cylindrical casing designed to conform to the
kettle body and steam jacket. The clearance between the inner and outer liner of the casing shall be sufficiently wide to keep the
exterior surface of the kettle from exceeding 140°F (60°C) during operation. The outer liner shall be corrosion-resistant steel
conforming to Specification A167, A176, or A240/A240M. The top of the casing shall be attached to the kettle’s canopy with
stainless steel threaded fasteners or rivets. The bottom of the casing shall terminate below the steam jacket.
7.1.4 Covers—Cover shall be designed so that it will not deform as a result of normal use. Covers shall be provided with a
handle as specified in 7.1.4.3. They shall be provided with a means of ensuring that condensation returns to the kettle.
7.1.4.1 One-Piece Cover—Non-tilting, 20, 30, and 40-gal (75.7, 113.6, and 151.4-L) kettles shall be provided with a one-piece
hinged or lift-off cover. If applicable, the construction of the hinge shall be such that it will retain the cover in an open position.
7.1.4.2 One-Piece, Spring-Assisted Cover—Non-tilting kettles that are 60 gal (227.2 L) or larger shall have a one-piece cover
with a spring-assisted lift device to keep the cover open over the kettle in any position.
7.1.4.3 Handles—The handle should be raised from the cover and located so as to prevent injury to the operator. The handle
shall be stainless steel and attached to the cover in accordance with ANSI/NSF Std. 4. A heat-insulating grip shall be provided on
the handle. The surface of the grip shall not exceed 120°F (48.9°C) during kettle operation when tested in accordance with Section
10.
7.1.5 Draw-Off Assembly—Unless otherwise specified, non-tilting kettles shall be provided with a minimum 2-in.
