NSF ANSI 20 contains requirements for bulk milk dispensers designed to dispense servings of milk or milk products by manual or machine actuation. This Standard does not apply to dispensing freezers (soft-serve machines). vending machines, or manual food and beverage dispensing equipment covered by the scope of other NSF standards.
Commercial bulk milk and milk product dispensing equipment materials and components covered under other NSF or NSF’ANSI Standards or Criteria shall also comply with the requirements therein. This Standard is not intended to restrict new design, provided that such design meets the minimum specifications described herein.
1.3 Alternate materials, design, and construction
While specific materials, design, arid construction may be stipulated in this Standard, commercial bulk milk dispensing equipment that incorporates alternate materials, design. and construction may be acceptable when such equipment meets the intent of the applicable requirements herein.
1.4 Measurement
Decimal and SI conversions provided parenthetically shall be considered equivalent. Metric conversions
and significant figure rounding have been made according to IEEE/ASTM SI 10.
