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 code 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 This American National Standard may be revised or withdrawn at any time.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 calling or writing the American National Standards Institute, 25 West 43rd Street, Fourth Floor, New York, NY 10036;

摘要：

ANSI AWWA B501-19 是针对氢氧化钠（俗称烧碱）的行业标准规范，由美国自来水厂协会（AWWA）于2019年更新发布。该标准详细规定了用于饮用水处理及工业水处理领域的氢氧化钠产品的物理化学性能、检测方法、包装标识、储存运输及安全要求，旨在确保烧碱在投加过程中不会影响水质安全或造成设备腐蚀。对于从事水处理、化工、市政供水及环保工程的专业人士而言，B501-19是采购、验收及合规审查时的关键参考文件，有助于提高工艺可靠性与运营效率。
