Standard Specification for Reach-in Refrigerators, Freezers, Combination Refrigerator/Freezers, and Thaw Cabinets

ABSTRACT
This specification covers the material, design, and construction requirements for reach-in refrigerators, freezers, combination refrigerator/freezers, and thaw cabinets that are stationary and of a vertical or horizontal configuration. Products covered by this specification are sorted into type: refrigerator (Type I), freezer (Type II), combination refrigerator/freezer (Type III), and thaw cabinet (Type IV); grade: vertical cabinet (Grade 1) and horizontal cabinet (Grade2); class: modular construction (Class 1) and unitary or single piece construction (Class 2); size; and style: manual loading (Style 1) and roll-in cart loading (Style 2). Materials used for the manufacture of the products shall be new and free of defects or reclaimed or recycled materials having the same quality as new materials and shall comprise of the following: corrosion-resistant steel, non-corrosion resistant steel (mild steel coated with zinc, chrome, nickel, or paint), aluminum alloys, seamless copper tubings, and corrosion-resistant material (for use in hardware, fittings, and fasteners). The product and its components shall be free of dirt, burrs, slivers, tool and grind marks, dents, and cracks. Castings, molded parts, and stampings shall be free of voids, sand pits, blowholes, and sprues. In addition, the assembly shall have no sharp edges or concealed objects that may cause injury. The products shall be tested for compliance to the requirements specified.
SCOPE
1.1 This specification covers the basic design and function of temperature regulated, continuous duty commercial, and marine refrigerators, freezers, combination refrigerator/freezers and thaw cabinets. The equipment will be stationary and of a vertical or horizontal type.
1.2 Equipment covered under this specification may contain a substance (or be manufactured with a substance) that harms public health and environment by destroying ozone in the upper atmosphere. This specification does not purport to address environmental regulations. It is the responsibility of the user of this specification to comply with environmental regulations.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.
