NSF Standards provide basic

11、criteria to promote sanitation and protection of the public health. Provisions for mechanical and electrical safety have not been included in this Standard because governmental agen-cies or other national standards-setting organizations provide safety requirements. Participation in NSF Standards dev

Preference is given to the use of performance criteria measurable by examination or testing in NSF Stand-ards development when such performa

The illustrations, if provided, are intended to assist in understanding their adjacent standard requirements. However, the illustrations may not include all requirements for a specific product or unit, nor do

14、 they show the only method of fabricating such arrangements. Such partial drawings shall not be used to justify im-proper or incomplete design and construction.

T

26、his Standard uses inch-pound units as the primary units with SI (metric) units provided in parentheses for informational purposes. The Joint Committee carried a motion that this convention be adopted in future revisions to this Standard. The SI units provided in parentheses generally represent a har

27、d conversion of the inch-pound units, meaning that the SI value may have been rounded to provide a reasonable and measurable dimension. Section 1.4 Measurement Added language specifies the use of significant figure rounding Section 2.0 Normative References Updated to reflect current designation, tit

28、le and proper citation. Normative references will be updated where applicable in the Food Equipment Family of Standards. Section 4.6 Beverage Equipment Cross-reference to annex B changed to NSF/ANSI 51. The method for conducting in unit extraction testing of beverage equipment was moved from this st

29、andard to Standard 51. Section 5.13.5 Covers Updated to reflect accessibility and cleanability of all surfaces of covers. Section 5.29.3 Glass Glass materials requirements were moved to NSF/ANSI 51 and a pointer placed in the FE Family of Stand-ards. Section 5.43.2 2009 Addendum This revision clarif

30、ied the requirements in 5.43 drains in steam tables and bains-marie units. Section 5.48 and 6.1.1 Food Warmer Language updated and intended to address heated cabinets intended to hold different types of non-potentially hazardous foods, such as pretzels, cookies, nacho chips, and so forth, to clarify

31、 the intended use of such equipment. These equipment not intended to hold potentially hazardous foods and marked in accordance with the newly adopted 5.48 are exempt from this performance test, similar to the exemption for proofing cabinets. Section 6.4.3 Acceptance Criteria In the 2005 publication

32、of Standard 4, the absolute value sign were removed from the calculation. The remov-al of the absolute value sign resulted in a negative log reduction. The newly adopted modification will result in a positive number. This Standard was developed by the NSF Joint Committee on Food Equipment using the

33、consensus process described by the American National Standards Institute. Suggestions for improvement of this Standard are welcome. This Standard is maintained on a Continuous Maintenance schedule and can be opened for comment at any time. Comments should be sent to Chair, Joint Committee on Food Eq

36、national Standard for Food Equipment Commercial cooking,rethermalization, and powered hot food holding and transport equipment 1 General 1.1 Purpose This Standard establishes minimum food protection and sanitation requirements for the materials, design, construction, and performance of commercial co

37、oking, rethermalization, and hot food holding and transport equipment and their related components. This Standard does not contain safety requirements. 1.2 Scope Equipment covered by this Standard includes, but is not limited to, ranges, ovens, fat/oil fryers, fat/oil filters, griddles, tilting grid

38、dle skillets, broilers, steam and pressure cookers, kettles, rotisseries, toasters, coffee makers and other hot beverage makers, component water heating equipment, proofing boxes and cabinets, hot food holding equipment, rethermalization equipment, and hot food transport cabinets. Section 7 of this

39、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 correctional facilities, mental health facilities, or some schools. For t

40、hese environments, where both sanitation and security are concerns, 7 contains exceptions to this Standard that shall only be applicable to the splash and non-food zones of food equipment provided with a security package. Equipment components and materials covered under other NSF or NSF/ANSI Standar

41、ds 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 Alternative materials, design, and construction While specific materials, design, and constructi

42、on 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 conversions provided parenthetically shall be considered equiva

43、lent. Metric conversions and significant figure rounding have been made according to IEEE/ASTM SI 10. 2014 NSF NSF/ANSI 4 2014 2 2 Normative references The following documents contain provisions that, through reference, constitute provisions of this NSF/ANSI Standard.
