It is not a specification. AWWA standards describe minimum requirements and do not contain all of the engineering and administra
3、tive 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 pub- lication of a standard does not constitut
4、e 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 standar
5、ds are intended to represent a consensus of the water industry that the product described will provide satisfactory ser- vice. When AWWA revises or withdraws this standard, an official notice of action will be placed on the first page of the Official Notice section of Journal American Water Works As
6、sociation. The action becomes effective on the first day of the month following the month of Journal American Water Works Association publication of the official notice. American National Standard An American National Standard implies a consensus of those substantially concerned with its scope and p
7、rovisions. 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 ap - proved the standard or not, from manufacturing, marketin
8、g, 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 encour - aged to
9、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 n oti Ce : The American National Standards Institute (ANSI) approval date on the front cover of this standard
10、 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 This American National Standard may be revised or withdrawn at any time.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 publication. Purchasers of American Natio
11、nal 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; 212.642.4900; or emailing infoansi.org.

18、SI/AWWA C562, Fabricated Aluminum Slide Gates; and ANSI/ AWWA C563, Fabricated Composite Slide Gates. ANSI/AWWA C542 describes only the design and performance of those actuat- ing devices applied to systems with operating pressures normally encountered in water utilities. Purchasers of electric moto
19、r actuators should carefully review the require- ments of this standard, evaluate the information to be provided to the manufacturer, and review the data to be supplied by the manufacturer. Such evaluations are essential to allow proper application of the electric motor actuator for the intended use
20、. ANSI/AWWA C542 references the National Electrical Manufacturers Association (NEMA),* which publishes standards and application guides for electrical equipment, enclosures, and components for various hazardous and nonhazardous service. Users of ANSI/AWWA C542 are cautioned to clearly specify the ap
21、plication requirements for the service. Such service may include depth and duration for submerged application, explosion-proof, and outdoor application. Specific requirements for controls and accessories and other items not covered by this standard shall be included in the purchase documents. Users
22、of this standard should consult the National Electrical Code and local codes for circuit breakers/disconnect switch requirements. III. Use of This Standard. It is the responsibility of the user of an AWWA standard to determine that the products described in that standard are suitable for use in the
23、particular application being considered. There are numerous lists throughout this standard describing various features of electric motor actuators. These lists are intended to be nonlimiting in nature and may not include all features necessary for a particular application or that a particular purcha
24、ser may desire. This standard includes certain options that shall be selected and specified by the purchaser to completely describe and obtain the actuator desired. In addition to the factors in Sec. III.A, Purchaser Options and Alternatives, other factors to be considered when sizing an actuator ar
25、e described in Sec. 4.3, Actuator Sizing. The following sum- marizes the options that shall be selected and the data that shall be covered in the pur- chase documents covering actuators manufactured in accordance with this standard. III.A. Purchaser Options and Alternatives. The following informatio
26、n should be provided or requested by the purchaser: * National Electrical Manufacturers Association, 1300 North 17th Street, Suite 1752, Rosslyn, VA 22209.
