NSF Testing Standards. Compare Drinking Water Filters Based On Industry Standards. Darkstar One Windows 7 Patch here. Introduction. When you purchase a gallon of gasoline for your car in the U. Nsf Ansi Standard 42 Pdf' title='Nsf Ansi Standard 42 Pdf' />Nsf Ansi Standard 42 Pdf ReaderS., are you confident that you actually received what you paid for Looking past the question of product quality, how do you know how much gasoline was added to your fuel tank You know because you purchase gasoline using a uniform standard of measure, the U. S. liquid gallon, established by a governmental entity, the National Institute of Standards and Technology. Furthermore, you rely upon another governmental entity responsible for local enforcement of weights and measures to regularly inspect the vendors gasoline pump to make certain that precisely a gallon of fuel actually is pumped on demand. Standards and, more importantly, testing against standards, are key to consumers being confident that they are receiving what they are paying for. Nsf Ansi Standard 42 Pdf File' title='Nsf Ansi Standard 42 Pdf File' />The application of standards and testing is equally important in the purchase of drinking water filters and delivery systems. It is the only objective means for a consumer to validate a drinking water system manufacturers product performance claims. There are innumerable drinking water filters and systems available in the market, and conclusive product test results support the consumers ability to evaluate and differentiate among them. Product testing conducted by a reputable and independent third party testing laboratory is the only way to ensure unbiased test results. However, in the complex sciences of chemistry and toxicology applicable to evaluating the quality of drinking water, awareness of the details behind the test results is critical to truly understanding a products capabilities. You cannot simply rely upon seeing a recognizable logo, you must delve deeper. The focus of this paper is on identifying the standards that apply to the products that are commonly utilized for treating drinking water at the point of use, and on what is behind standards compliance that makes the standards so important. The paper also will outline the testing process employed by the recognized leader in testing for the water filtration industry, NSF International. Finally, the paper will address how a leading drinking water filter manufacturer, Multipure International, employs standards and independent testing from product design to manufacturing and packaging to help consumers evaluate and compare the companys products to competitive alternatives. Nsf Ansi Standard 42 Pdf FilesDrinking Water System Standards in the United States. The Safe Drinking Water Act SDWA originally was passed by Congress in 1. The law was amended in 1. SDWA authorizes the United States Environmental Protection Agency EPA to set national health based standards for drinking water to protect against both naturally occurring and man made contaminants that may be found in drinking water. The EPA, individual states, and water systems then work together to make certain that these standards are met. Founded in 1. 91. American National Standards Institute ANSI is a private, not for profit organization serving as the official U. S. representative to the International Organization for Standardization ISO and, via the U. S. National Committee, the International Electrotechnical Commission IEC. ANSI is also a member of the International Accreditation Forum IAF. ANSI accredits and coordinates several hundred organizations and committees that develop standards for approval as American National Standards based in part on evidence of due process and consensus. Nsf Ansi Standard 42 Pdf Creator' title='Nsf Ansi Standard 42 Pdf Creator' />ANSI provides the criteria and procedures for achieving due process and determining consensus, as well as other requirements for the development, approval, maintenance and coordination of American National Standards. These ANSI criteria and requirements are accepted by each accredited standards developer as a condition of accreditation.

The DION IMPACT 910270US Coating System is Certified by NSF International to the requirements of NSFANSI Standard 61 Drinking Water System ComponentsHealth. NSF was founded in 1. Today, NSF is the leading global, independent third party certification and testing organization for products that affect water quality and food safety. NSF is recognized as the leading authority in the development of consensus, national standards that bring together experts from the regulatory, manufacturing, academic, scientific research, and consumer industries. These comprehensive standards provide the basis by which product manufacturers can demonstrate the quality, reliability and performance of their products, and through which buyers, consumers and health officials can be assured of their safety and benefits. The NSF Drinking Water Treatment Units DWTU Certification Program for Point Of Use POU and Point Of Entry POE systems and components was first established in the early 1. NSF DWTU Standard in 1. Based upon Maximum Contaminant Level MCL standards established by the EPA, and working within the auditing framework defined by ANSI, NSF sets the standards for compliance and testing for drinking water filters and systems. Today, a total of seven NSF DWTU Standards have been adopted, to which hundreds of companies have certified thousands of POU and POE systems and components used around the world to improve and protect drinking water quality. At a regional level, a limited number of states enforce their own compliance standards for drinking water systems sold within the state. States with their own standards include California, Colorado, Iowa, Massachusetts, and Wisconsin. In most instances, states will accept an NSF certification as acceptable proof of drinking water system performance. NSF also is an active participant in testing and certification at the international level. Countries throughout the world are developing and adopting standards for the evaluation of POU and POE drinking water treatment units. For example, the European Committee for Standardization CEN has been developing such standards, also referred to as European Norms, for all of Europe. NSF independently tests, audits, certifies, trains and consults for the food, water, health science, sustainability and consumer product sectors.

NSFANSI Standards for Drinking Water Treatment Units. Of the seven NSF DWTU Standards, this paper primarily focuses on the two that are applicable to POU devices employing filtration technology NSFANSI Standard 4. Aesthetic Effects. NSFANSI Standard 5. Health Effects. NSFANSI Standard 4. POU and POE systems designed to reduce specific aesthetic or non health related contaminants such as chlorine, taste and odor, and particulates that may be present in public or private drinking water. The scope of Standard 4. The Standard applies most commonly to carbon filtration, but it also applies to other filtration media such as ceramic filters. Its worth noting that a device may be certified under this and other NSFANSI Standards for specific contaminant reduction e. Standard, not necessarily removing all of the contaminant present in the source water. With regard to particulate reduction, several classes are used to define the level of particulate reduction, ranging from Class VI for those devices removing coarse particulates of 5. Class I for drinking water treatment units that reduce the smallest submicron particles i. NSFANSI Standard 5. POU and POE systems designed to reduce specific health related contaminants that may be present in public or private drinking water. Standard 5. 3 establishes minimum requirements for material safety, structural integrity, product literature, and health related contaminant reduction performance claims. The most common technology addressed by Standard 5.
