AWWA Standard

This document is an American Water Works Association (AWWA) standard. It is not a specification. AWWA standards

describe minimum requirements and do not contain all of the engineering and administrative information normally

contained in specifications. The AWWA standards usually contain options that must be evaluated by the user of the

standard. Until each optional feature is specified by the user, the product or service is not fully defined. AWWA publication

of a standard does not constitute endorsement of any product or product type, nor does AWWA test, certify, or approve

any product. The use of AWWA standards is entirely voluntary. This standard does not supersede or take precedence

over or displace any applicable law, regulation, or codes of any governmental authority. AWWA standards are intended

to represent a consensus of the water industry that the product described will provide satisfactory service. When AWWA

revises or withdraws this standard, an official notice of action will be placed in the Official Notice section of Journal AWWA.

The action becomes effective on the first day of the month following the month of Journal AWWA publication of the official

notice.

American National Standard

An American National Standard implies a consensus of those substantially concerned with its scope and provisions. An

American National Standard is intended as a guide to aid the manufacturer, the consumer, and the general public. The

existence of an American National Standard does not in any respect preclude anyone, whether that person has approved

the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not

conforming to the standard. American National Standards are subject to periodic review, and users are cautioned to obtain

the latest editions. Producers of goods made in conformity with an American National Standard are encouraged to state

on their own responsibility in advertising and promotional materials or on tags or labels that the goods are produced in

conformity with particular American National Standards.

Caution Notice: The American National Standards Institute (ANSI) approval date on the front cover of this standard indicates

completion of the ANSI approval process. This American National Standard may be revised or withdrawn at any time. ANSI

procedures require that action be taken to reaffirm, revise, or withdraw this standard no later than five years from the

date of ANSI approval. Purchasers of American National Standards may receive current information on all standards by
