10、 judgment. NSF shall not be responsible to anyone for the use of or reliance upon this Standard by anyone. NSF shall not incur any obligation or liability for damages, including consequential damages, arising out of or in connection with the use, interpretation of, or reliance upon this Standard. NS
11、F Standards provide basic 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 agencies or other national standards-setting organizations provide safety requirements. Participa
12、tion in NSF Standards development activities by regulatory agency representatives (federal, local, state) shall not constitute their agencys endorsement of NSF or any of its Standards. Preference is given to the use of performance criteria measurable by examination or testing in NSF Standards develo
13、pment when such performance criteria may reasonably be used in lieu of design, materials, or con-struction criteria. The illustrations, if provided, are intended to assist in understanding their adjacent standard requirements. However, the illustrations may not include all requirements for a specifi
14、c product or unit, nor do they show the only method of fabricating such arrangements. Such partial drawings shall not be used to justify improper or incomplete design and construction.

24、d holding and transport equipment. This 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 p
25、arentheses generally represent a hard conversion of the inch-pound units, meaning that the SI value may have been rounded to provide a reasonable and measurable dimension. This version of NSF/ANSI 4 2016 includes the following revisions: Issue 18: This issue added new language for Sections 5 and 8 r
26、egarding floorless heating compartments. In addition, this ballot proposes the addition of informative Annex D, Flooring Recommendations for Proofers and Ovens Constructed Without Floors. Issue 23: Section 4.6, regarding Beverage equipment was removed as it is now superseded by the requirement in NS
27、F/ANSI 51 2014 Issue 24: Language was added to the test method in sections 6.2.2.1 and 6.7.2.1 covering open top hot food holding equipment and open heated merchandisers. This Standard was developed by the NSF Joint Committee on Food Equipment using the consensus process described by the American Na
28、tional 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 Equipment at standardsnsf.org, or c/o NSF Intern

31、oking, 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 cooking, rethermalization, and hot food holding and
32、 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 griddle skillets, broilers, steam and pressure cooker
33、s, 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 Standard pertains to food handling and processing
34、 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 these environments, where both sanitation and secu
35、rity 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 Standards or Criteria shall also comply with the require
36、ments 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 construction may be stipulated in this Standard, equipment
37、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 equivalent. Metric conversions and significant figure r
38、ounding have been made according to IEEE/ASTM SI 10. 2016 NSF NSF/ANSI 4-2016 2 2 Normative references The following documents contain provisions that, through reference, constitute provisions of this NSF/ANSI Standard.
