NSF/ANSI 60-2011

This version of NSF/ANSI 60 - 2011 includes the following revisions:Issue 39: It was established that the Single Product Allowable Concentration (SPAC) for bromate will be lowered from 0.005 mg/L to 0.003 mg/L on January 1, 2013. An informational annex (Annex G) was created to address this requirement until the implementation date. In addition, the bromate acceptance criteria for low-bromate hypochlorites was raised from 0.001 mg/L to 0.003 mg/L. Issue 46: Requirements for the evaluation of perchlorate in hypochlorites were added. This includes establishment of SPACs, criteria for analytical methods, sample requirements, and requirements to inform the user of production date and provide references to recommended handling and storage requirements. Issue 47: This issue added the requirement of tamper resistant/ tamper-evident seals on all containers of water treatment chemicals sold to water suppliers under 3.9. Issue 49: This issue included revisions to multiple sections of the Standard. The definition of typical use level was added and the definition of maximum use level was revised for clarification under 2. 3.2.1 was revised to clarify that toxicology studies for each product submission are not required if SPACs are established for each chemical contaminant of concern under Annex A. Method E was updated in Annex B (B.3.6) to reference the specific analysis methods with regards to sample preservation and storage instruction. The remaining references to mercury testing were deleted from Annex B (B.3.6 and B.4.2.3) (The requirement for mercury analysis of elemental chlorine was removed from Table 6.1 in an earlier version of the Standard). An editorial revision was made to Method E (B.3.6), correcting a typo in which a multiple factor of 100 was incorrectly shown to reflect 100 times the evaluation dose. The value was revised to reflect the correct number 10.
