NSF ANSI 52:2017 pdf download.Supplemental flooring.
Supplemental flooring covered by this Standard includes, but is not limited to, supplemental flooring for use in food preparation, dry storage, and warewashing areas.
Flooring components and materials covered under other NSF or NSF/ANSI Standards or Criteria shall also comply with the requirements therein. This Standard is not intended to restrict new supplemental flooring design. provided that such design meets the minimum specifications described herein.
1.3 Alternate materials, design, and construction
While specific materials, design. and construction may be stipulated in this Standard, flooring that incorporates alternate materials, design, or construction may be acceptable when such flooring meets intent of the applicable requirements herein.
1.4 Measurement
Decimal and SI conversions provided parenthetically shall be considered equivalent. Metric conversions and significant figure rounding have been made according to IEEE/ASTM SI 10.
