1、Designation: F2891 10Standard Specification forCommercial Bulk Milk Dispensers, MechanicallyRefrigerated1This standard is issued under the fixed designation F2891; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last re

2、vision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers commercial bulk milk dispens-ers which are for dispensing milk in the commercial andinstitutional f

3、ood service establishments. These commercialbulk milk dispensers are self-contained, manually-operated,gravity-fed, mechanically refrigerated cabinet(s) with lift-up orpush-type valves. These units are intended to dispense refrig-erated milk and fluid milk products.1.2 The values stated in inch-poun

4、d 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.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresp
