Material goods molded from plastics have been a part of everyday life for many decades, but in the early 1960s, a new group of pla
37、stics better suited to meet more demanding applications was discovered. These materials have greatly improved properties, such as strength and stiffness, and are known as engineering plastics. With the introduction of this new class of plastics, engineers were able to achieve design objectives that
38、previously had seemed almost beyond reach. The water meter industry as a whole began underwriting experiments with plastic materials as far back as the 1950s. From 1963 to 1968, two principal research pro- grams were sponsored by the meter suppliers under the auspices of the American Water Works Ass
39、ociation (AWWA) at the Armour Research Institute, Chicago, and later at Columbia University, New York City. These programs primarily focused on plastic meter main-case designs and materials. Plastic material research in the water meter industry has paid great dividends and has resulted in the design
40、 of many meter components from engineering plastics. Signicant improvements, such as corrosion resistance, dimensional stability, self- lubrication, low mass, and superior surface nishes have resulted in improved meter accuracies with longer life. When designing meter components from plastic, todays
41、 engineer has a choice of thousands of plastic compound formulations. Although many plastics appear identical, there are often vast differences in their physical properties, and it takes considerable know-how to select the one best suited for a particular application. In addition, plastics used in w
42、ater meter design often contain various enhancing or reinforcing agents to give components greater rigidity, strength, and dimensional stability. I.B. History. The extensive use of plastic in the design of plastic water meter parts was recognized in the Jan. 24, 1971, revision of ANSI/AWWA C700, Col
43、d-Water MetersDisplacement Type, Bronze Main Case. The use of synthetic polymers as an alternative material for all parts except the main case was one of the major revisions. At the 1972 AWWA annual convention, the rst domestic positive-displacement water meter with a plastic main case (rather than
44、the traditional bronze main case) was * American National Standards Institute, 25 West 43rd Street, Fourth Floor, New York, NY 10036. Copyright 2015 American Water Works Association. All Rights Reserved. x introduced. During the next 10 years, three more meter suppliers introduced plastic main-case
45、meters. The subject of plastic main-case materials not meeting the current standard was discussed at the 1974 meeting of the AWWA Meter Standards Committee. The com- mittee chairman stated that the manufacturers of these meters should initiate a request for change at the next revision. The revision
46、of ANSI/AWWA C700 in 1977 did not include synthetic polymers as an alternative main-case material because the subcommittee could not reach agree- ment. The subject was tabled to be considered at the next revision in 1982. Between 1982 and 1985, revising ANSI/AWWA C700 to include synthetic polymers a
47、s a main- case alternative became an issue. To resolve this controversy, an ad hoc committee was appointed by the Standards Council. A Mar. 4, 1985, ad hoc committee report recom- mended that the Standards Council direct the Water Meter Committee to “appoint a new subcommittee to develop a new stand
48、ard for displacement-type water meters with plastic main cases, including consideration of appropriate allowable nutation speed for this type of meter.” This recommendation was accepted by the Standards Council in June 1985. Because of the diversity of available materials and the continual developme
49、nt of new and improved materials, this standard will not specify any one material but will use the term suitable engineering plastic. For reference purposes only, typical materials used presently for water meter designs and found in ASTM* specications are cited. The rst edition of ANSI/AWWA C710 was approved by the AWWA Board of Directors Jan. 25, 1988. Subsequent editions were approved on Jan. 28, 1990, June 17, 1995, June 16, 2002, and Jan. 25, 2009. This edition was approved on Jan. 24, 2015. I.C. Acceptance. In May 1985, the US Envir
