17、ication organizations to be used when certifying products to NSF/ANSI 60. Background A change was made to the California Code of Regulations (CCR, adopted on March 9, 2008) that required annual recertification of drinking water treatment chemicals to NSF/ANSI 60: Drinking Water Treatment Chemicals-H
18、ealth Effects. This was prompted by concerns that while some certification organizations provided annual retesting of treatment chemicals other organizations allowed for up to five years to pass in between retests. In 2009 Section 3.8 Conformity Assessment, which contained product testing and facili
19、ty inspection requirements, was incorporated into NSF/ANSI 60-2009a. However, there were concerns that requirements for the conformity assessment process (facility inspections and periodic retest requirements) in NSF/ANSI 60 would not receive sufficient attention from ANSI during the periodic review
20、s, as they constitute only a small portion of the issues governed by that standard. It was determined that there would be more focus on conformity assessment if the requirements were placed in a separate standard for conformity assessment. A task group was formed to develop the Standard, and include
21、d representatives from industry, certification organizations, water utilities, and public health agencies. In 2010, the task group was expanded further to include the input of many more manufacturers representatives. It was noted during the discussion that when NSF/ANSI 60 was originally devised, mo
22、st production of direct additives occurred in or was overseen by owners from countries where corruption played an insignificant role in business. Today, a substantial portion of the production of direct additives to water has moved to countries where this is no longer the case. Transparency Internat
23、ionals Corruption Perceptions Index (CPI) is perhaps the most famous of a number of such indexes constructed to aid international businesses in understanding the conditions they will face in the different countries in which they do business. Such conditions include labor rates, public holidays, ende
24、mic diseases, labor laws, business etiquette and corruption. The index has been constructed annually since 1995 for Transparency International by Prof. Johann Graf Lambsdorff of the University of Passau. The process sources 16 independent surveys of countries, and a country must appear in at least t
25、hree of these sources in order for a score to be calculated. The CPI was revised in 2012 from a scale of 0-10 to 0-100, where the lowest possible level of perceived corruption would equal a score of 100 and the highest possible level of perceived corruption would equal a score of 0. As production mo
26、ves to a wider variety of source countries and raw material sourcing is further diversified due to cost considerations, there must be a method to differentiate locations where oversight can be relaxed, and where it must be maintained. Therefore NSF/ANSI 223 establishes additional requirements for lo
27、cations in countries with a CPI score of . 4 Transparency International, Alt-Moablt 961, 10559 Berlin, Germany, .

This Standard is setting requireme
41、nts for certification programs in which products shall be certified to NSF/ANSI 60. Formal certification documents (ISO/IEC 17065, section 7.8, and ISO/IEC 17020) shall indicate that the certification system utilized fulfills this Standard, by noting: “Products certified via a product certification
42、program in accordance with NSF/ANSI 223.” 4 Product testing (during initial certification and on-going surveillance) As part of initial certification and on-going surveillance (ISO/IEC 17065, section 7.9, and ISO/IEC 17020), except as noted below, a product shall be sampled and tested at least once
43、per calendar year for the chemistry-specific analytes contained in Tables 4.1, 5.1, 6.1 visual inspection of production, process and equipment; collection of samples pursuant to 4; validation of formulations; validation of approved suppliers; review of analytical procedures and methods (if applicabl
44、e); review of records related to formulation control; and review of chemical stock control records.
