CRGI in MRO Magazine: NSF-61 Gaskets for Potable Water Applications

The September issue of MRO Magazine contains an article on NSF-61 gaskets for potable water applications authored by Canada Rubber Group Inc. (CRGI) fluid sealing expert, Bill Searle.

Developed by a team of scientists, industry experts and key industry stakeholders, the NSF-61 standard sets health effects criteria for many water system components including sealing materials such as rubber sheet. Increasingly, in North America, products are required to comply with the NSF- 61 standard by most governmental agencies that regulate drinking water supplies. NSF-61 certified gasket materials are the preferred materials for drinking water and sanitary service applications.

NSF/ANSI 61 includes criteria for testing and evaluating products to ensure they do not leach contaminants into water, thus creating a health concern or hazard. Developed by a team of scientists, industry experts and key industry stakeholders, NSF/ANSI 61 sets health effects criteria for many drinking water system components, including sealing materials such as rubber sheet.

In the MRO Magazine article, Bill Searle highlights why gaskets and seals compliant to NSF-61 are becoming increasingly important in certain industry sectors. NSF-61 is quite comprehensive. The standard establishes minimum criteria for impurities and contaminants that may be released indirectly into drinking water from products, components and materials, including joining and sealing materials such as gaskets and seals.

The wider adoption of the NSF-61 standard is serving to drive an increased availability of gaskets and sealing materials that are NSF/ANSI 61 compliant. The NSF-61 standard requires that only gaskets and seals approved and certified by the National Sanitation Foundation (NSF) can be used in facilities and in applications where the standard has been adopted as a requirement. Certification of gaskets and seals provides an assurance that the products have passed all the required physical property tests and that they are approved for use in situations where compliance to NSF/ANSI 61 is a requirement.

To service potable water and sanitary service applications, CRGI is now offering Teadit NA1082SAN NSF-61 certified gasket material. The NA1082SAN gasket material was developed by Teadit to allow compliance for drinking water system components with NSF-61, from source to tap. Certification of the NA1082SAN gasket material to NSF-61 provides a high level of assurance that the sheet is safe for use in drinking water service.

Teadit NA1082SAN gasket material is specifically formulated to pass criteria established in the NSF-61 standard for sealing materials, as well as providing excellent resistance to conductivity. Compressed fiber sheet technology provides mechani­cal and service characteristics unmatched by standard elastomeric grades.
