This standard pertains to the in-ground installation of steel pipeline
37、s for use in the distribution and transmission of water, air, and other products in water system facilities. It has been prepared by the AWWA Standards Committee on Steel Pipe, initially formed as Committee A7A in 1939. At that time, the Steel Water Pipe Manufacturers Technical Advisory Committee wa
38、s organized as a subsidiary group to function as a source of technical information for the parent committee. Committee A7A and its successors, Committee 8310D and the AWWA Standards Committee on Steel Pipe, have assumed responsibility for all AWWA standards and manuals pertaining to steel pipe, fitt
39、ings, linings and coatings, field installations, and related items. In 1996 the AWWA Standards Council directed the Standards Committee on Steel Pipe to develop a standard for the installation of steel pipelines and their appur- tenances used in water treatment or conveying facilities. The first edi
40、tion of AWWA C604 was approved by the AWWA Board of Directors on Feb. 12, 2006. The second edition was approved on Jan. 23, 2011. The present edition of C604 was approved on Jan. 14. 2017. I.B. Discussion. ANSI/AWWA C604 addresses the installation of steel pipe 4 in. (100 mm) in diameter and larger
41、typically used in the water industry. ANSI/ AWWA C604 anticipates the use of pipe produced in a fabricators shop or pipe mill that meets the stringent design, quality control, and testing requirements of AWWA Manual M11, ANSI/AWWA C200, and the applicable AWWA steel pipe lining and coating standards
42、. I.C. Acceptance. In May 1985, the US Environmental Protection Agency (USEPA) entered into a cooperative agreement with a consortium led by NSF International (NSF) to develop voluntary third-party consensus standards and a certification program for direct and indirect drinking water additives. Othe
43、r members of the original consortium included the Water Research Foundation (formerly AwwaRF) and the Conference of State Health and Environmental Managers (COSHEM).

All Rights Reserved. x 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 contac
45、t with, drinking water rests with individual states.* Local agencies 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, inc
46、luding 1. Specific policies of the state or local agency. 2. 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. 3. Other references, including AWWA standards, Food Chemica
47、ls 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 have authority to accept or accredit certificatio
48、n 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 (MAL) of a contaminant for substances not regulat
49、ed by a USEPA final maximum contaminant level (MCL). The MALs of an unspecified list of “unregulated contaminants” are based on toxicity testing guidelines (noncarcinogens) and risk characterization methodology (carcinogens). Use of Annex A procedures may not always be identical, depending on the certifier. ANSI/AWWA C604 does not address additives requirements. Thus, users of this standard should consult the appropriate state or local agency having jurisdiction in order to 1. Determine additives requirements, including applicable standards. 2. Determi
