ISO 1992-4:1974 PDF Download

ISO 1992-4:1974 specifies a technique for assessing the defrosting process of commercial refrigerated cabinets. This standard applies exclusively to cabinets used for the sale and exhibition of food goods, and it specifies testing circumstances that are identical to those used in the temperature test defined in ISO 1992 Part 3.

The defrosting test is designed to assess the effectiveness and efficiency of the defrosting process used in refrigerated cabinets. It ensures that the cabinets can maintain ideal temperatures for food storage and display by properly eliminating accumulated frost during the defrosting process.

It is crucial to note that the ISO 1992-4:1974 test is not appropriate for cabinets or components that require human defrosting. The standard's goal is to ensure that commercial refrigerated cabinets meet the quality and performance standards for keeping and presenting food goods.
