This Standard contains requirements for equi
24、pment and devices that manually dispense food or beverages, in bulk or in portions. This Standard may also be applied to components of food and beverage dispensing equipment. Issue 12 This revision updated the Normative References and boilerplate language in: 1.4 Measurement and 6.1 Cleaning and san
25、itization procedures. This Standard was developed by the NSF Joint Committee on Food Equipment using the consensus process described by the American National Standards Institute. Suggestions for improvement of this Standard are welcome. Comments should be sent to Chair, Joint Committee on Food Equip

28、Equipment Manual food and beverage dispensing equipment 1 General 1.1 Purpose This Standard establishes minimum food protection and sanitation requirements for the materials, design, construction, and performance of manual food and beverage dispensing equipment and their related components. 1.2 Scop
29、e This Standard contains requirements for equipment and devices that manually dispense food or beverages, in bulk or in portions. The materials, design, and construction requirements of this Standard may also be applied to an item that is manufactured as a component of food and beverage dispensing e
30、quipment. This Standard does not apply to vending machines, dispensing freezers, or bulk milk dispensing equipment covered by the scope of other NSF Standards. Dispensing equipment components and materials covered under other NSF or NSF/ANSI Standards or Criteria shall also comply with the requireme
31、nts therein. This Standard is not intended to restrict new unit design, provided that such design meets the minimum specifications described herein. 1.3 Alternate materials, design, and construction While specific materials, design, and construction may be stipulated in this Standard, dispensing equ
32、ipment that incorporates alternate materials, design, or construction may be acceptable when such equipment meets the applicable requirements herein. 1.4 Measurement Decimal and SI conversions provided parenthetically shall be considered equivalent. Metric conversions and significant figure rounding
