Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope1.1 This specification covers co
3、mmercial ice cream, softserve, and shake freezers, which freeze and dispense frozenproduct (dairy, yogurt, custard, etc.) on a continuous basis.Included in this specification are conventional and heat-treatment freezers.1.2 Equipment covered under this specification may containa substance (or be man
4、ufactured with a substance) that harmspublic health and environment by destroying ozone in theupper atmosphere. This specification does not purport toaddress environmental regulations. It is the responsibility ofthe user of this standard to comply with environmentalregulations (see 7.5).1.3 The valu
5、es stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with
6、its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
