23、eral 1.1 Purpose This Standard establishes minimum sanitation 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 non
24、work surfaces of food service equipment on which direct food 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
25、used in conjunction with cutting boards or other means of preventing 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 no
26、t intended to restrict new product design, provided that such 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
