    NSF/ANSI Standard 61 Overview

    NSF/ANSI Standard 61 Overview


    This information will help explain the purpose, scope, and content of NSF/ANSI Standard 61.

    1. NSF/ANSI Standard 61 Drinking Water System Components - Health Effects is the standard that establishes minimum health effects requirements for materials, components, products, or systems that contact drinking water, drinking water treatment chemicals, or both.

    2.NSF/ANSI Standard 61 (NSF 61) covers many items, including, but are not limited to:

    a. Pipes, fittings and related products

    b.Protective barrier materials (coatings, linings, liners, cement, cement ad-mixtures, etc.)

    c.Joining and sealing materials (adhesives, lubricants, elastomers, etc.)

    d.Process media (activated carbon, sand, ion exchange resin, regenerated media etc.)

    e.Mechanical devices used in treatment and distribution (valves, pumps, filters, chlorinators, etc.)

    f.End-point devices dispensing drinking water (faucets, end-point control valves, riser tubes, supply stops, etc.)

    3.NSF/ANSI Standard 61 does not address all aspects of product use. The standard is focused and limited to addressing potential health effects except where specific application and performance standards are referenced. Some items not addressed by this standard are performance (such as burst pressure), taste and odor, microbiological growth support, and electrical safety. Other standards address these aspects of products, and NSF can provide testing and certification to these as well.

    4.NSF/ANSI Standard 61 is divided into nine Sections and four Annexes as noted below.

    a.Section 1= Purpose, Scope, Limitations, Normative References of the standard

    b.Section 2= Definitions of various terms (note there are more definitions in sections 4 through 9 and Annex A)

    c.Section 3= General requirements, required information, review of formulations, minimum testing batteries, etc.

    d. Section 4= Specific requirements for Pipe and related products like PVC, PE, Cu, Fe, etc. pipe, fittings, and potable water materials

    e.Section 5= Specific requirements for Protective Barrier Materials/products such as sealers, coatings, paint, primer, mortar, Portland cements, cement ad-mixtures, etc.

    f.Section 6= Specific requirements for Joining and Sealing Materials/products such as o-rings, gaskets, lubricants, adhesives, elastomer materials, etc.

    g.Section 7= Specific requirements for Process and filtration media products such as ion exchange, activated carbon, sand, manganese, aluminum silicates, etc.

    h.Section 8= Specific requirements for Mechanical Devices products such as filters, valves, pumps, chemical generators, chemical feeders, etc.

    i.Section 9= Specific requirements for Mechanical Plumbing Devices such as faucets and other end point devices

    j.Annex A= Toxicology Review and Evaluation Procedures (risk assessment and normalization details)

    k.Annex B= Detailed product/material evaluation information (details of test waters for rinse, conditioning, exposure, etc.)

    l.Annex C= Acceptable Materials, details of existing types (such as certain stainless steel materials) and how to add new ones

    m.Annex D= Normative drinking water criteria (USEPA, Health Canada, NSF etc. derived short and long term exposure limits)

    n.Annex E= Informative drinking water criteria that are intended to be used as guidance in the determination of evaluation criteria for those compounds that do not have normative evaluation criteria established.

    o.Annex F= Contains reduced evaluation criteria for lead in drinking water. The reduced criteria are currently being held in abeyance and are due to be in effect on July 1, 2012.

    p.Annex G= This annex was developed to establish a lead content evaluation procedure for use when product is required to meet a ≤0.25% weighted average lead content requirement as exists in California and Vermont.
