Now it’s easier, faster, and less expensive to change or add certain grades of stainless steel parts to your NSF Standard 61 Certified products.

NSF/ANSI Standard 61: Drinking water system components – Health effects now allows additional types of stainless steel as acceptable materials for use in the manufacturing of drinking water equipment.

The range of acceptable materials was expanded with the issue of the 2005 version of the standard.

Annex C of the standard has been updated to include additional stainless steel materials used in the manufacture of drinking water products such as pumps, valves, filters, tanks, chemical feeders and generators, well screens, well casing, drop pipe, tube, fittings, and other equipment.

For existing NSF Standard 61 Listed manufacturers of products this means you now have more choices at less cost for your materials of design and construction. For non-NSF Standard 61 Listed manufacturers of products with stainless steel components and materials, it’s now even easier, faster, and less expensive to get your products Tested and Certified by NSF, the leader in public health safety.

To order a copy of the standard go to http://www.nsf.org/business/standards_and_publications/

The annex defines the evaluation process for materials that have been submitted for qualification as acceptable materials into the standard.

Current Acceptable Materials in Annex C of NSF Standard 61 include:

Stainless Steel Type 304, 304L, 316, 316L, 2205,2203,2101,2304.

No, individual products are not allowed to bear the NSF Certification Mark unless the products are Certified by NSF and appear in NSF Listings at www.nsf.org. However products that use these grades of stainless steel that are accepted under Annex C of NSF 61 can receive reduced testing batteries. This can save money and time in the NSF Certification process.
