ANSI/AWWA C210-15, Standard for Liquid-Epoxy Coatings and Linings for Steel Water Pipe and Fittings

AWWA solicits public comments on all proposed new AWWA Standards, and on all proposed revisions, reaffirmations, or withdrawals of existing AWWA Standards. The referenced standards project is being considered for approval and the publication of this notice begins AWWA’s 30-day public comment period. An electronic public review copy of the proposed standard can be purchased for review during the comment period for $20 each. Comments must be submitted in writing to the AWWA contact listed below no later than the last day of the comment period specified herein. Such comments shall be specific to the section(s) of the standard under review and include sufficient detail so as to enable the reader to understand the commenter's position, concerns and suggested alternative language, if appropriate.

The AWWA Comment Period is now closed and the review copies are no longer available.

The review copy will be edited for publication and may also be revised as appropriate based on any comments received during the public comment period. Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.

Final publication of the standard may take several months. When it is available, a notice will be published in the official notice section of Journal – American Water Works Association. The standard becomes an effective AWWA standard on the first day of the month following such publication in Journal – American Water Works Association.

SCOPE
This standard describes the material and application of shop- and field-applied, liquid epoxy coatings and linings used in the water-supply industry for steel water pipelines installed underground or underwater, under normal construction conditions.
1.1.1    Conditions not described in this standard. The coating systems described in this standard are not intended for use on pipe that will be bent after the coating or lining system has been applied.
1.1.2 Coating and lining systems. The coating and lining systems may consist of any of the following three types: (1) a two-part, chemically cured epoxy primer and one or more coats of a different two-part, chemically cured epoxy topcoat; (2) two or more coats of the same two-part, chemically cured epoxy, in which case the first coat shall be considered as the prime coat; or (3) a single coat of a two-part, chemically cured epoxy.
1.1.2.1 Maximum temperature. AWWA steel pipe coating and lining standards are based on the maximum service temperature of potable water. Consult the epoxy manufacturer for conditions and limitations.

MAJOR REVISIONS
Major changes made to the standard in this revision include the following:
1. The title of the standard was changed to be consistent with other AWWA steel pipe coating standards.
2. Sec. III.A Purchaser Options was updated to reflect changes in the standard.
3 Sec. 2 References was updated.
4. The definition for potable water was added to Sec. 3 Definitions.
5. A new Sec. 4.2.3 was added to address certification to NSF/ANSI 61 if the lining system is in contact with potable water.
6. Old Sec. 4.3 Coating System was renamed to Epoxy System and revised to be consistent with other AWWA steel pipe coating and lining standards and the epoxy thickness information was moved to a new Sec. Sec. 4.4.3.7 Epoxy Thickness, for better readability.
7. Old Sec. 4.3.3 Applied, cured coating requirements, was moved to Sec. 5.5.2 Cure, to reduce redundancy and improve continuity of standard.
8. Table 1 was revised to reflect prequalification requirements and a minimum dielectric strength requirement was added.
9. Table 2 was revised to reflect quality control requirements and requirements for appearance and cure were added and the ASTM D3359 adhesion method A was deleted to be consistent with industry practice.
10 Old Sec. 4.4.Coating Application was renamed to Epoxy Application and slightly revised for consistency.
11. A new Sec. 4.4.3.3 on field coating of holdback areas was added.
12. Sec. 4.6.1.1 Preparation for field welded joints was revised and a surface profile depth for abrasive blast cleaning was added.
13. Old Sec. 4.6.3 Electrical Inspection was deleted and combined with Sec. 5.5.4 Electrical continuity inspection, to reduce redundancy and improve continuity.
14. Old Sec. 4.7.3.3 Cure was deleted and combined with Sec. 5.5.2 Cure, to reduce redundancy and improve continuity.
15. Old Sec. 4.7.3.4 Electrical inspection for continuity, was deleted and combined with Sec. 5.5.4 Electrical continuity inspection, to reduce redundancy and improve continuity.
16. Section 4.8 was modified to be consistent with other AWWA steel pipe coating and lining standards and now references AWWA C604.
17. Section 5 Verification was revised and the heading titles and format were updated to be consistent with the new language and format being used in AWWA steel pipe coating and lining standards.
18. Sec. 5.2.1.2 Cathodic disbondment was updated with more detail.
19. A new Sec. 5.2.1.3 on dielectric strength was added.
20. The quality control requirements for cure (Sec. 5.5.2), dry film thickness (Sec. 5.5.3), electrical continuity inspection (Sec. 5.5.4) and adhesion (Sec. 5.5.5) were updated.
21. A new Sec. 5.3 Quality Assurance and Records was added.
22. A new quality control requirement for appearance was added Sec. 5.5.1.
23. Sec. 5.5.5 Adhesion was revised and new sections on frequency of testing (Sec. 5.5.5.1) and rejection of pipe (Sec. 5.5.5.2) were added.
24. Sec. 5.6 Rejection was updated and expanded.
25. Section 6 Delivery was modified to be consistent with other AWWA steel pipe coating and lining standards.
26. Sec. 6.3 Affidavit of Compliance was revised to be consistent with the AWWA boilerplate language used in other AWWA standards.
