AWWA standards describe minimum requirements and do not contain all of the engineering and administrative information normally cont
3、ained in specifications. The AWWA standards usually contain options that must be evaluated by the user of the standard. Until each optional feature is specified by the user, the product or service is not fully defined. AWWA pub- lication of a standard does not constitute endorsement of any product o
4、r product type, nor does AWWA test, certify, or approve any product. The use of AWWA standards is entirely voluntary. This standard does not supersede or take precedence over or displace any applicable law, regulation, or codes of any governmental authority. AWWA standards are intended to represent
5、a consensus of the water supply industry that the product described will provide satisfactory service. When AWWA revises or withdraws this standard, an official notice of action will be placed on the first page of the Official Notice section of Journal - American Water Works Association. The action
6、becomes effective on the first day of the month following the month of Journal - American Water Works Association publication of the official notice. American National Standard An American National Standard implies a consensus of those substantially concerned with its scope and provisions. An Americ
7、an National Standard is intended as a guide to aid the manufacturer, the consumer, and the general public. The existence of an American National Standard does not in any respect preclude anyone, whether that person has ap - proved the standard or not, from manufacturing, marketing, purchasing, or us
8、ing products, processes, or procedures not conforming to the standard. American National Standards are subject to periodic review, and users are cautioned to obtain the latest editions. Producers of goods made in conformity with an American National Standard are encour - aged to state on their own r
9、esponsibility in advertising and promotional materials or on tags or labels that the goods are produced in conformity with particular American National Standards.

The AWWA Standards Coun
17、cil authorized development of this standard in 1979. The standard was developed by the AWWA Standards Committee on Polyelectrolytes and was approved by the AWWA Board of Directors on June 17, 1990. The second edition of this standard was approved on June 21, 1998. The third edition of ANSI/AWWA B452
18、 was approved on Feb. 12, 2006. This edition was approved on Jan. 19, 2014. I.C. Acceptance (water supply service applications). 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 thir
19、d-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 Water Research Foundation*) and the Conference of State Health and Environ
20、mental 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 agencies may

22、red 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 two standards developed under the direction of NSF,* NSF/ANSI 60, Drinking Water Treatment ChemicalsHealth Effects, and NSF/ANS
23、I 61, Drinking Water System ComponentsHealth Effects. Various certification organizations may be involved in certifying products in accor- dance with NSF/ANSI 60. Individual states or local agencies have authority to accept or accredit certification organizations within their jurisdiction. Accredita
24、tion of certi- fication organizations may vary from jurisdiction to jurisdiction. Annex A, “Toxicology Review and Evaluation Procedures,” to NSF/ANSI 60 does not stipulate a maximum allowable level (MAL) of a contaminant for substances not regulated by a USEPA final maximum contaminant level (MCL).
25、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 B452 addresses additives requireme
26、nts in Sec. 4.6 of the standard. The transfer of contaminants from chemicals to processed water or to residual solids is becoming a problem of greater concern. The language in Sec. 4.6 is a recommenda- tion only for direct additives used in the treatment of potable water to be certified by an accred
27、ited certification organization in accordance with NSF/ANSI 60 Drinking Water Treatment ChemicalsHealth Effects. However, users of the standard may opt to make this certification a requirement for the product. Users of this standard should consult the appropriate state or local agency having jurisdi
28、ction 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 product certification. I.D. Acceptance (wast
29、ewater service applications). This is the first revision of ANSI/AWWA B452 that addresses wastewater service applications and standards. II. Special Issues. II.A. Safety. EPI-DMA polyamines are not considered to be toxic as household products nor primary skin irritants by the Consumer Product Safety
30、 Commission (US Federal Hazardous Substances Act). Good housekeeping procedures and personal cleanliness are recommended when handling EPI-DMA polyamine. * NSF International, 789 N.

31、ses should be worn when handling EPI-DMA polyamines. Appropriate first-aid practices should be followed in all cases of exposure. In case of eye contact, flush with plenty of water for at least 15 min. If irritation develops, call a physician. Consult the SDS for the specific product for safety proc
32、edures before handling any EPI-DMA polyamines product or solution. II.B. Spill Control. EPI-DMA polyamines should be disposed of according to federal, state or provincial, and local regulations. A dike should be formed around any spill area to contain as much material as possible, and the contained
33、material should be shoveled, scooped, or pumped, as appropriate, into suitable disposal containers. Any remaining material should be removed by absorbing it on vermiculite or other suitable absorbing material and placed in a sealed container for disposal. The spill area should be thoroughly hosed wi
34、th water after all possible polymer has been scooped up, absorbed, or wiped up because liquid product can make floors very slippery. Use of warm water is beneficial. III. Use of This Standard. It is the responsibility of the user of an AWWA standard to determine that the products described in that s
35、tandard are suitable for use in the particular application being considered. III.A. Purchaser Options and Alternatives. This A WWA standard can be used to prepare a purchase specification, but is not itself a specification because it cannot address requirements unique to the purchasers specific situ
36、ation and does not establish business relationships. In addition, this EPI-DMA polyamines standard does not establish physical and chemical property specifications for any one EPI-DMA polyamine product, because the physical and chemical properties of EPI-DMA polyamines do not always relate to their
37、performance in specific applications. Below are requirements that the user might consider when developing an EPI- DMA polyamines product purchase specification. This standard requires the supplier to provide a product technical data sheet in addition to an SDS for each product and requires specific
38、information to be included in the product technical data sheet. The information in a product technical data sheet may be used to establish or comply with purchase specifications. 1. Compliance with the requirements of the latest revision of ANSI/AWWA Standard B452, EPI-DMA Polyamines, for potable water supply service applications (water) or wastewater service applications (wastewater), as applicable. 2. For potable water applications, compliance with NSF/ANSI 60, Drinking Water Treatment ChemicalsHealth Effects. Copyright 2014 American Water Works Association. All Rights Reserved.
