32、s standard describes crosslinked polyethylene (PEX) pressure tubing for use primarily as potable service lines in the construction of underground water distribution systems. This standard describes tubing made with a materials designation code of PEX 1306, or higher, according to ASTM F876. This sta

33、ndard describes tubing in nominal dimensions in. (13 mm) through 3 in. (76 mm) with a standard dimension ratio of 9 (SDR9) and pressure class of 160 psi. I.B. History. On June 18, 2002, the American Water Works Association (AWWA) Committee on Polyolefin Pressure Pipe and Fittings was approached to d

34、evelop a standard describing PEX for water service applications. On June 15, 2004, the polyolefin committee unanimously approved and authorized the development of a new standard for PEX, in. (13 mm) through 3 in. (76 mm), for water service. A new PEX subcommittee was also formed at this time to begi

35、n development of this standard within AWWA. The first edition was approved by the AWWA Board of Directors on June 11, 2006. This edition was approved on Jan. 16, 2016. I.C. Acceptance. In May 1985, the US Environmental Protection Agency (USEPA) entered into a cooperative agreement with a consortium

36、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 E

37、nvironmental 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 agencie

Other references, including AWWA standards, Food Chemicals Codex, Water Chemicals Codex, and other standards considered appropriate by the state or local agency. Various certification organizations may

42、be involved in certifying products in accor- dance with NSF/ANSI 61. Individual states or local agencies have authority to accept or accredit certification organizations within their jurisdictions. Accreditation of certi- fication organizations may vary from jurisdiction to jurisdiction. Annex A, “T

43、oxicology Review and Evaluation Procedures,” to NSF/ANSI 61, does not stipulate a maximum allowable level (MAL) of a contaminant level (MCL). The MALs of an unspecified list of “unregulated contaminants” are based on toxicity test- ing guidelines (noncarcinogens) and risk characterization methodolog

44、y (carcinogens). Use of Annex A procedures may not always be identical, depending on the certifier. Users of this standard should consult the appropriate state or local agency having jurisdiction in order to: 1. Determine regulatory requirements, including applicable standards related to compounds a

45、nd chemicals that are regulated as a matter of public health. 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 product certification. II.
