NSF/ANSI 332 was developed by the Resilient Floor Covering Institute (RFCI) with the assistance of NSF International through a multistakeholder committee. It is a tiered standard, with products achieving a certification level of conformant, silver, gold and platinum.

The standard is divided into six categories, based on a 90-point scale (plus Innovation):

  • Product design: 30 points
  • Product manufacturing: 29 points
  • Long-term value: 9 points
  • End-of-Life management: 10 points
  • Corporate governance: 12 points
  • Innovation: maximum of 10 points

Certification is awarded when 11 prerequisites are satisfied, and the required amount of optional points is achieved.

  • Conformant: All prerequisites and minimum of 25 points
  • Silver: All prerequisites and minimum of 35 points
  • Gold: All prerequisites and minimum of 45 points
  • Platinum: All prerequisites and minimum of 60 points


Certification to this standard provides a market-based definition and path to more sustainable flooring through performance requirements for the individual product and the manufacturing organization. Once certified, manufacturers can leverage the NSF Sustainability Certified Mark to gain marketplace preference and increase the likelihood of product specification.
