3、imum 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
4、 is not fully defined. AWWA pub- lication of a standard does not constitute endorsement of any product or product type, nor does AWWA test, certify, or approve any product.

20、ssure of the piping system. Because of the number of variables involved, it is recommended that the repair clamp manufacturer be consulted regarding model selection, proper application, and the anticipated performance of the repair clamp for specific end-user pipe repair needs prior to product purch
21、ase and usage. When * NSF International, 789 North Dixboro Road, Ann Arbor, MI 48105. Both publications available from National Academy of Sciences, 500 Fifth Street, NW, Washington, DC 20001.

22、encountered, the manufacturer should be consulted to determine whether a repair clamp is appropriate for the repair. II.B. Chlorine and Chloramine Degradation of Elastomers. The selection of materials is critical for water service and distribution piping in locations where there is a possibility tha
23、t elastomers will be in contact with chlorine or chloramines. Documented research has shown that elastomers such as gaskets, seals, valve seats, and encapsulations may be degraded when exposed to chlorine or chloramines. The impact of degradation is a function of the type of elastomeric material, ch
24、emical concentration, contact surface area, elastomer cross section, and environmental conditions as well as temperature. Careful selection of and specifications for elastomeric materials and the specifics of their application for each water system component should be considered to provide long-term
25、 usefulness and minimum degradation (swelling, loss of elasticity, or softening) of the elastomer specified. 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 particular applicatio
26、n being considered. III.A. Purchaser Options and Alternatives. The fo llowing information should be provided by the purchaser: 1.
