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.

31、in; and resist the effects of foods, cleaning compounds, sanitizers, and other substances that may contact the materials in the intended use environment. 4.1 Conformance with NSF/ANSI 51 High pressure decorative laminates shall conform to the requirements in NSF/ANSI 51 applicable to the zone in whi
32、ch the material is used. 4.2 Stain resistance High pressure decorative laminates shall demonstrate “no effect” when exposed to test reagents “a” through “j” and shall show no more than a “moderate effect” when exposed to test reagents “k” through “o“ when tested in accordance with section 3.4 of NEM
33、A LD 33. 4.3 High temperature resistance High pressure decorative laminates for use as work surfaces shall demonstrate no more than a “slight effect” when tested in accordance with section 3.6 of NEMA LD 33. 4.4 Wear resistance The base paper of high pressure decorative laminates shall not be expose
34、d after the completion of 400 cycles when tested in accordance with section 3.13 of NEMA LD 33. 4.5 Ball impact resistance High pressure decorative laminates shall not fracture when the test is conducted in accordance with section 3.8 of NEMA LD 33. The height of the ball drop shall correspond to th
35、e end use as follows: Height of drop nonwork surface 15 in (381 mm) work surface 35 in (889 mm) 4.6 High pressure decorative laminates shall have permanent markings indicating the manufacturers name, the trade designation, the production location designator (if the product is manufactured at more th
36、an one location), and an indicator specifying whether the laminate is intended for use on work or nonwork surfaces. 4ASTM International, 100 Barr Harbor Dr., West Conshohocken, PA 19428 . NSF 2012 NSF/ANSI 35 2012 3 5 Limitations to use 5.1 High pressure decorative laminates shall not be used on sur
37、faces subject to: cutting, chopping, and similar operations; routine contact with heated objects in excess of 275 F (135 C); sustained heat of 150 F (66 C) or more (e.g., hot food inserts, broilers, griddles); and excessive moisture. This shall not preclude use on shelves; water, ice, and wait stati
38、ons; and hand sinks. 5.2 High pressure decorative laminates shall not be used on surfaces subject to intentional, expected, or reasonable direct food contact during normal operations.
