1.1 This specification covers basic design and function of rapid pull down refrigerators or freezers, or a combination of both, sometimes referred to as “blast chillers,” “blast freezers,” or “quick chillers.” 1.2 This equipment is for professional use in commercial and other similar food service establishments for rapid intermediate chilling or freezing of hot food products cooked to a specific temperature within a specified time period and holding the food at a safe temperature when not engaged in the chilling or freezing process. 1.3 This standard addresses equipment that is self-contained, manually operated, and has a mechanically refrigerated cabinet(s) of a vertical or horizontal cabinet type. Equipment may be a “reach-in” for stationary or fixed shelving or a “roll-in” for mobile carts. This equipment may also be installed under a service counter. 1.4 This standard does not cover blast chilling tunnels, continuous blast-chilling and blast freezing equipment, bakery combined freezing and storage units. 1.5 The standard does not cover “shock freezers” or equipment that uses nitrogen or other consumable products in their function. 1.6 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. 1.7 Units— The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.8 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. 1.9 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.
