It is not a specification. AWWA standards describe mini- mum requirements and do not contain all of the engineering and administrative ination normally contained in specifications. The AWWA standards usually contain options that must be uated by the user of the standard. Until each optional feature is specified by the user, the product or service is not fully defined. AWWA publication of a standard does not constitute endorse- ment of any product or 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 a consensus of the water supply industry that the product de- scribed 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 classified advertising section of Journal AWWA. The action becomes effective on the first day of the month following the month of Journal AWWA 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 American 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 approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not coning 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 conity with an American National Standard are encouraged to state on their own responsibility in advertising and promo- tional materials or on tags or labels that the goods are produced in conity with particular American National Standards. Caution notiCe The American National Standards Institute ANSI approval date on the front cover of this standard indicates comple- tion of the ANSI approval process. This American National Standard may be revised or withdrawn at any time. ANSI procedures require that action be taken to reaffirm, revise, or withdraw this standard no later than five years from the date of publication. Purchasers of American National Standards may receive current ination on all standards by calling or writing the American National Standards Institute, 25 West 43rd Street, Fourth Floor, New York, NY 10036; 212 642-4900.

Materials and SafetySec. 4.2 Materials4.2.1 . Materials shall comply with the requirements of the Safe Drinking Water Act and other federal requirements. Safety4.2.2 . Necessary precautions shall be taken to protect personnel and property from accidents caused by falls, hazardous materials, fire, explosion, and other dangers. The s and practices defined in SSPC-PA 3 shall be fol- lowed, along with those prescribed by applicable federal, provincial, state, and local regulations. Coating SystemSec. 4.3 Liquid‑epoxy coatings4.3.1 . The coatings used in this standard shall be based on liquid chemically cured epoxies. The curing agent may be an amine, amine-adduct, phenalkamine, polyamide, or other epoxy curing agents; the epoxy may be modified with coal tar, phenolic, or other modifiers. Materials used in both the primer and finish coats shall be products of one manufacturer. Shelf life. The component parts shall be stored in unopened origi-4.3.1.1 nal containers at temperatures not to exceed the manufacturer’s recommendation. They shall show no instability or settling beyond a state permitting easy, complete redispersion to a smooth, homogeneous consistency. When properly mixed and ap- plied, acceptable drying and curing will result. Stored material that has exceeded the manufacturer’s stated shelf life shall not be used. Coating thickness.4.3.2 The minimum and maximum dry film thickness DFT of the lining and external coating shall be specified by the purchaser. Dry film thickness shall con to the manufacturer’s printed data and shall be tested in accordance with SSPC-PA 2. Minimum thickness.
