NSF ANSI 35-2017 pdf free download – High pressure decorative laminates for surfacing food service equipment.
This Standard establishes minimum sanitation requirements for the materials and fabrication of high pressuredecorative 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 foodservice equipment on which direct food contact during normal preparation or holding operations is notintended, expected,or reasonable.Applications of high pressure decorative laminates covered by thisStandard inciude wait stations, service counters,and other counters when used in conjunction with cuttingboards 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 orCriteria exist shall also comply with the applicable requirements therein. This Standard is not intended torestrict 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 meetthe minimum requirements described herein.
1.4 Measurement
Decimal and Sl conversions provided parenthetically shall be considered equivalent. Metric conversions andsignificant figure rounding have been made according to lEEE/ASTM Sl 10.

Materials
This section contains requirements that are intended to ensure that high pressure decorative laminates resistwear; resist penetration by vermin; and resist the effects of foods, cleaning compounds, sanitizers, and othersubstances that may contact the materials in the intended use environment.
4.1 Conformance with NSF/IANSI 51
High pressure decorative laminates shall conform to the requirements in NSF/ANSI51 applicable to the zonein which the material is used.
4.2 Stain resistance
Stain resistance testing shall be performed in accordance with section 3.4,CLEANABILITY/STAINRESISTANCE of NEMALD 3-20053.Test specimen stain resistance score shall be no greater than:
– reagents 1 through 10: 1) No effect – All stain reagents removed with no impairment to surfaceappearance.Any change in gloss due to the cleaning procedure is permitted.
– reagents 11 through 15:2) Moderate effect – A difficult to perceive stain visible from all angles anddirections.Any change in gloss due to the cleaning procedure is permitted.
4.3 High temperature resistance
High pressure decorative laminates for use as work surfaces shall undergo high temperature resistancetesting in accordance with section 3.6, HIGH TEMPERATURE RESISTANCE of NEMA LD 3-20053.Testspecimen heat resistance score shall be no greater than:
– b.Slight effect – A change in color or surface finish only visible at certain angles or directions.4.4 Wear resistance
Wear resistance testing shall be performed in accordance with section 3.13,WEAR RESISTANCEof NEMALD 3-20053.Test specimen wear resistance score shall be no greater than 400 cycles.NSF ANSI 35 pdf download
