34、erved. ix Foreword This foreword is for information only and is not a part of ANSI/AWWA C205. I. Introduction. I.A. Background. Cementmortar-lined-and-coated steel pipe was first used in the United States in the late 1800s. Some of the first pipelines were in service for almost a century by the time
35、 the first national standard was written. However, it was not until the 1920s that a practical method of plant-applied cementmortar lining was developed. The first plant-applied linings were installed by standing the pipe on end, placing a tapered plug with a rope attached to the leading end inside
36、the pipe, placing enough cement mortar on top of the plug to coat the pipe, and then pulling the plug up through the pipe. Improvements in the lining process were developed, and the centrifugal process for plant-applied cementmortar lining emerged. Cementmortar-lined and cementmortar-coated steel pi
37、pe combines the physical strength of steel with the protective qualities of cement mortar. The lining, applied centrifugally, creates a smooth, dense finish that protects the pipe from tuberculation and provides a measure of corrosion protection. The smooth interior surface provides a high flow coef
38、ficient for the design life of the pipeline under normal operating condi- tions. In addition, the cementmortar coating results in a tough, durable, and rugged coating that forms an alkaline environment where oxidation or corrosion of the steel is inhibited. I.B. History. The first edition of this st
39、andard, designated 7A.7-41, Standard Specifications for CementMortar Protective Coating for Steel Water Pipe of Sizes 30 Inches and Over, was approved by the AWWA Board of Directors on June 26, 1941. Before that, a tentative draft had been published in the January 1940 Journal - American Water Works
40、 Association for review and comment. The first edition provided a section for the field application of cementmortar lining, which was deleted by action of the Board of Directors effective June 30, 1951. Pending the promulgation of AWWA C602, CementMortar Lining of Water Pipe- lines4 In. (100 mm) and
41、 LargerIn Place, the ninth, tenth, and eleventh printing of 7A.7 (AWWA C205) continued to carry the withdrawn section. The next edition, published in 1962, was a major revision and provided for pipe sizes of 4 in. (100 mm) and larger. The standard was subsequently revised in 1971, 1980, 1985, 1989,
42、1995, 2000, and 2007. This edition was approved on Jan. 22, 2012. Copyright 2012 American Water Works Association. All Rights Reserved. x 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)
43、 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 American Water Works Association Research Foundation (AwwaRF, now the Water Research Foundation) and the Conferenc
44、e of State Health and 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
45、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, including 1. An advisory program formerly admini
46、stered by USEPA, Office of Drinking Water, discontinued on April 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
47、Effects. 4. 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 be involved in certifying products in accor- dance with NSF/ANSI 61. Individual states
48、or local agencies have authority to accept or accredit certification organizations within their jurisdiction. 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
49、 allowable level (MAL) 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.
