Stone Council, NSF Develop Standard

Ann Arbor, MI, Nov. 21, 2013 -- The Natural Stone Council and NSF International said they have developed the first sustainability assessment standard for stone.

NSC 373 Sustainability Assessment for Natural Dimension Stone defines criteria for the sustainable development aspects of dimensional stone production while harmonizing environmental requirements for stone quarrying and production.

NSC utilized NSF International’s technical expertise as an American National Standards Institute (ANSI)-accredited standards developer to help create the consensus-based standard.

Certification to NSC 373 by quarries and processors is the first step in the product certification process for natural dimension stone.
