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 Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.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 protective exterior coatings that consist of cold-applied liquid adhesives and prefabricated tapes and their applications to special sections, connections, and fittings to be used for underground and underwater steel water pipelines protected with organic coatings, such as those described in ANSI[1]/AWWA C203, ANSI/AWWA C210, ANSI/AWWA C213, ANSI/AWWA C214, ANSI/AWWA C215, and ANSI/AWWA C216. These liquid adhesives and tapes can be used for repair of ANSI/AWWA C214 machine-applied coatings in accordance with the tape manufacturer’s recommendations. These liquid adhesives and tapes are not intended for use with either exposed steel joints or sections of steel pipe where coatings of cement mortar or concrete have been applied directly onto the bare steel pipe. Tape coatings conforming to this standard may be field- or shop applied.

1.1.1 Maximum temperatures. AWWA pipe coating standards are written for and based on the service temperature of potable water. Cold-applied tape coatings have performed at higher temperatures. Consult the coating manufacturer for conditions and limitations.
1.1.2 Conditions not included in this standard. This standard does not include the additional materials and procedures that may be required for difficult conditions, such as those encountered in some submarine pipelines, casing pipe, river crossings, and pipelines in exceptionally rocky areas. Also, it is not intended to describe conditions of extended exposure aboveground after application. When extended periods of aboveground exposure are contemplated, the tape manufacturer should be consulted for specific recommendations.

MAJOR REVISIONS
Major changes made to the standard in this edition include the following:
1. The title of the standard was changed to be consistent with other AWWA steel pipe standards.
2. Sec. 2 References was updated.
3. Table 1 was revised.
4. Sec. 4.3 Material Requirements, was revised to include prequalification requirements of the coating system (Table 2) and quality control requirements of the applied coating system (Table 3).
5. The requirements for abrasive blast cleaning were revised (Sec. 4.4.2.2).
6. The requirements for tape coating repair were revised (Sec. 4.4.6).
7. Sec. 4.5 Field Procedures, was rewritten to conform to the language used in other AWWA steel pipe coating standards.
8. The handling, bedding, and backfill information included in the previous edition of C209 in Sec. 4.5 has now been included in AWWA C604 and the reader is referred to C604.
9. Sec. 5 Verification, was rewritten to be consistent with other AWWA steel pipe coating standards.
10. A new Sec. 5.2 Prequalification of coating materials testing, was added.
11. Sec. 5.2.7 Cathodic Disbondment, was modified to further define the cathodic disbondment test evaluation method.
12. A new Sec. 5.3 Quality assurance and records, was added.
13. A new Sec. 5.4 Inspection and testing by the purchaser, was added.
14. A new Sec. 5.5 Quality requirements of coating systems, was added.
15. Sec. 5.5.3 Adhesion was expanded to include additional requirements.
16. A new Sec. 5.6 Rejection was added.
17. Appendix A was removed to be consistent with other steel pipe coating standards.
