This paper presents NSF/ANSI 419 Public Drinking Water Equipment Performance – Filtration, a new NSF/ANSI national standard for microfiltration (MF) and ultrafiltration (UF) membrane modules. This new standard establishes performance testing protocols that are consistent with the product-specific microbial challenge testing requirements for Cryptosporidium removal credits under the USEPA Long Term 2 Enhanced Surface Water Treatment Rule (LT2 Rule). The completed standard was published in January 2015. NSF/ANSI 419 allows for a Cryptosporidium removal performance certification to accompany certification to NSF/ANSI 61 for the wetted materials. With the new NSF/ANSI 419 performance standard for membrane modules, States can be assured that test data generated following the standard’s testing protocol is of high quality, and that a consensus test protocol was followed to generate the test data.
