NSF Publishes 140 Guidance Manual

NSF International, an Ann Arbor, Mich.-based third-party certification organization, has released a
guidebook to assist manufacturers through the NSF/ANSI 140-2007 Sustainable Carpet Assessment
Standard certification process. The guidebook is intended not only to simplify the use of NSF 140,
but also to provide consistency of data collection and documentation required for certification.

The NSF/ANSI 140-2007 Standard is used to evaluate broadloom and tile carpet floor coverings
in commercial and institutional applications. Initiated by the Dalton, Ga.-based Carpet and Rug
Institute and developed by the NSF Joint Committee for Sustainable Carpet, the standard establishes
criteria for sustainable manufacturing processes, reclamation and end-of-life management, efforts
to minimize adverse public health and environmental impacts, energy usage and efficiency, quality
control and record keeping, and innovation.

Carpets receiving NSF 140 certification contribute toward building project totals under the
US Green Building Council’s Leadership in Energy and Environmental Design Green Building rating
system in several categories.
