NSF 2014 NSF/ANSI 2-2014 1 2014 NSF NSF/ANSI 2-2014 NSF International Standard for Food Equipment Food equipment 1 General 1.1 Purpose This Standard establishes minimum food protection and sanitation requirements for
31、the materials, design, fabrication, construction, and performance of food handling and processing equipment. 1.2 Scope Equipment covered by this Standard includes, but is not limited to, bakery, cafeteria, kitchen, and pantry units and other food handling and processing equipment such as tables and
32、components, counters, hoods, shelves, and sinks. Section 7 of this Standard pertains to food handling and processing equipment that has been designed and manufactured for special use purposes. Food equipment designed and manufactured with a security package is utilized in environments such as correc
33、tional facilities, mental health facilities, or some schools. For these environments, where both sanitation and security are concerns, 7 contains exceptions to this Standard that shall only be applicable to the splash and nonfood zones of food equipment provided with a security package. Equipment co
34、mponents and materials 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 unit design, provided that such design meets the minimum specifications described herein. 1.3 Alternate materials, design, a
35、nd construction While specific materials, design, and construction may be stipulated in this Standard, equipment that incorporates alternate materials, design, or construction may be acceptable when such equipment meets the intent of the applicable requirements herein. 1.4 Measurement Decimal and SI
36、 conversions provided parenthetically shall be considered equivalent. Metric conversions and significant figure rounding have been made according to IEEE/ASTM SI 10. 2 Normative references The following documents contain provisions that, through reference, constitute provisions of this NSF/ANSI Stan
