Preference is given to the use of performance criteria m
11、easurable by examination or testing in NSF Standards development when such performance criteria may reasonably be used in lieu of design, materials, or construction criteria. The illustrations, if provided, are intended to assist in understanding their adjacent standard requirements. However, the il

20、 requirements for the materials, design, fabrication, construction, and performance of special purpose food handling and processing equipment and devices not fully covered by other individual standards. This Standard uses inch-pound units as the primary units with SI (metric) units provided in paren
21、theses 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 parenthesis generally represent a hard conversion of the inch-pound units, meaning that the SI value may have been rounded to provide
22、 a reasonable and measurable dimension. Issue 7 This revision updated normative references in section 2 and affirm proposed new language for section 5 covering the use of casters and gliders. This Standard was developed by the NSF Joint Committee on Food Equipment using the consensus process describ
23、ed by the American National Standards Institute. Suggestions for improvement of this Standard are welcome. Comments should be sent to Chair, Joint Committee on Food Equipment at standardsnsf.org, or c/o NSF International, Standards Department, P.O. Box 130140, Ann Arbor, Michigan, 48113-0140, USA. 2

26、d protection and sanitation requirements for the materials, design, fabrication, construction, and performance of special purpose food handling and processing equipment and devices not fully covered by other individual standards. 1.2 Scope Equipment covered by this Standard includes, but is not limi
27、ted to, specialty equipment items or devices that have special, complex, or multiple functions such as refrigeration heating equipment, and refrigerated tumblers equipment. These are applicable provisions and additional specific requirements or exceptions as might be needed for proper evaluation of
28、devices or equipment for which individual standards do not exist. The requirements of this Standard shall apply to all specialty equipment items except when equipment components and materials are covered under other NSF or NSF/ANSI Standards or criteria. Components and materials covered by other NSF
29、 or NSF/ANSI Standards or criteria shall comply with the requirements of each relevant standard or criteria to which that particular equipment component or material applies. This Standard is not intended to restrict new unit design, provided that such design meets the minimum specifications describe
30、d herein. 1.3 Alternate materials, design, and 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 applicable requirements herein.
31、1.4 Measurement Decimal and SI conversions provided parenthetically shall be considered equivalent.

40、ls used in the manufacture of food handling and processing equipment resist wear, penetration by vermin, and the effects of foods, heat, cleaning compounds, sanitizers, and other substances that may contact the materials in the intended use environment. Materials used in unexposed non-food zone area
41、s shall be exempt from all requirements in 4. 4.1 Conformance with NSF/ANSI 51 Materials shall conform to the requirements in NSF/ANSI 51 applicable to the zone in which the material is used. 4.2 Solder Solder containing lead as an intentional ingredient shall not be used in a food zone or splash zo
