21、yvinyl Chloride (PVC) and Molecularly Oriented Polyvinyl Chloride (PVCO) Pressure Pipe and Fittings. I.B. History. In 1966, the American Water Works Association (AWWA) appointed Committee 8350-D to study and report on the adaptability of plastic pipe for use within the water industry. The committee
22、presented its report on June 6, 1967, at AWWAs annual conference. The report included a recommendation that a task group be appointed to prepare standards for the use of plastic materials. The AWWA Standards Committee on Thermoplastic Pressure Pipe Standards Committee was established in 1968. In Jun
23、e 1988, the Thermoplastic Pressure Pipe Committee was divided into two separate committees: the Polyvinyl Chloride Pressure Pipe and Fittings Standards Committee and the Polyolefin Pressure Pipe and Fittings Standards Committee. ANSI/AWWA C900 was the first thermoplastic pipe standard approved by th
24、e AWWA Board of Directors in June of 1975. This is the sixth edition of ANSI/AWWA C900. Previous revisions to ANSI/AWWA C900 were prepared by the AWWA Stan- dards Committee and approved in Jan. 1981, Jan. 1989, June 1997, and June 2007. This edition of ANSI/AWWA C900 was approved on Jan. 16, 2016. *

In May 1985, the US Environmental Protection Agency (USEPA) entered into a cooperative agreement with a consortium
26、 led by NSF International (NSF) to develop voluntary third-party consensus standards and a certification program for direct and indirect drinking water additives. Other members of the original consortium included the Water Research Foundation (formerly AwwaRF) and the Conference of State Health and
27、Environmental Managers (COSHEM). The American Water Works Association (AWWA) and the Association of State Drinking Water Administrators (ASDWA) joined later. In the United States, authority to regulate products for use in, or in contact with, drinking water rests with individual states.* Local agenc
28、ies may choose to impose requirements more stringent than those required by the state. To evaluate the health effects of products and drinking water additives from such products, state and local agencies may use various references, including 1. An advisory program formerly administered by USEPA, Off
29、ice of Drinking Water, discontinued on Apr. 7, 1990. 2. Specific policies of the state or local agency. 3. Two standards developed under the direction of NSF : NSF/ANSI 60, Drinking Water Treatment ChemicalsHealth Effects, and NSF/ANSI 61, Drinking Water System ComponentsHealth Effects. 4. Other ref
30、erences, including AWWA standards, Food Chemicals Codex, Water Chemicals Codex, and other standards considered appropriate by the state or local agency. Various certification organizations may be involved in certifying products in accor- dance with NSF/ANSI 61. Individual states or local agencies ha
31、ve authority to accept or accredit certification organizations within their jurisdictions. Accreditation of certi- fication organizations may vary from jurisdiction to jurisdiction. Annex A, “Toxicology Review and Evaluation Procedures,” to NSF/ANSI 61 does not stipulate a maximum allowable level (M
32、AL) of a contaminant for substances not regulated by a USEPA final maximum contaminant level (MCL). The MALs of an unspecified list of “unregulated contaminants” are based on toxicity testing guidelines * Persons outside the United States should contact the appropriate authority having jurisdiction.

ANSI/AWWA C900 does not address additives requirements. Thus, users of this standard should consult the appro
35、priate state or local agency having jurisdiction in order to 1. Determine additives requirements including applicable standards. 2. Determine the status of certifications by parties offering to certify products for contact with, or treatment of, drinking water. 3. Determine current information on pr
36、oduct certification. II. Special Issues. The pressure-class designation requirements and pressure design recommendations presented in this standard are different from those in AWWA Manual M23, PVC PipeDesign and Installation, second edition (2002). The requirements of this standard take precedence o
37、ver the design recommendations in AWWA Manual M23, second edition. Inconsistencies with AWWA M23 and this standard should be discussed with the manufacturer. The committee intends to revise the third edition of M23 to align with this standard. II.A. Selection of Pressure Class. The minimum pressure
38、class of the pipe selected should be equal to or greater than the system working pressure. The sum of the system working pressure and occasional surge pressure should not exceed 1.60 times the pressure class of the pipe. The system working pressure and recurring surge pressure should be analyzed usi
39、ng the method in Sec. 4.7. If surge pressures govern the selection of the pressure class, consideration should be given to removal of the cause of surge pressures or to the incorporation of surge suppressors in the system. II.B. Concern Regarding UV Light Effects. The effect of ultraviolet (UV) ligh
40、t on PVC pipe should be insignificant. User concerns such as outdoor storage should be discussed with the manufacturer. 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
41、 application being considered. III.A. Purchaser Options and Alternatives. The following items should be provided by the purchaser: 1. Standard to be usedthat is, ANSI/AWWA C900, Polyvinyl Chloride (PVC) Pressure Pipe and Fabricated Fittings, 4 In. Through 60 In. (100 mm Through 1,500 mm), of latest revision. 2. Whether compliance with NSF/ANSI 61, Drinking Water System ComponentsHealth Effects, is required. Copyright 2016 American Water Works Association. All Rights Reserved.
