23、 requirements for the materials and fabrication of high pressure decorative laminates (HPDL). This Standard does not contain safety requirements. 1.2 Scope This Standard applies to high pressure decorative laminates for use as work and nonwork surfaces of food service equipment on which direct food

24、contact during normal preparation or holding operations is not intended, expected, or reasonable. Applications of high pressure decorative laminates covered by this Standard include wait stations, service counters, and other counters when used in conjunction with cutting boards or other means of pre

25、venting direct food contact with the laminate. High pressure decorative laminates used on equipment for which other NSF or NSF/ANSI Standards or Criteria exist shall also comply with the applicable requirements therein. This Standard is not intended to restrict new product design, provided that such

26、 design meets the minimum specifications described herein. 1.3 Minimum requirements Variations other than those specifically mentioned in this Standard may be used provided that materials meet the minimum requirements described herein. 1.4 Measurement Decimal and SI conversions provided parenthetica

27、lly 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 Standard.
