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 Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.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 establishes minimum requirements for microcrystalline wax and petrolatum tape coating systems for steel water pipe and fittings.

MAJOR REVISIONS
Major revisions made to the standard in this edition include the following:
1. Added a new Sec. 1.1.3 to the Scope for substrates other than carbon steel.
2. In Sec. 3: Definitions Applicator was added.
3. Sec. 4 Headings were revised to be consistent with AWWA standardized wording and headings.
4. Sec. 4.1 Equipment was revised to be consistent with the updated wording in other steel pipe coating standards.
5. Sec. 4.2 Materials and Workmanship was revised to be consistent with the updated wording in other steel pipe coating standards and sections on safety and personnel were added. 
6. Sec. 4.4 Surface preparation was revised to establish consistent language between similar AWWA steel pipe coating standards and to remove redundant language already included in the referenced SSPC standards.
7. Moved Tables from Sec. 4.3 to Sec. 5 to be consistent with other AWWA standards.
8. Sec. 4.6 Coating Fittings and Specials was added.
9. Sec. 4.4.4 was moved to its own Sec. 4.7 Coating Repair.
10. Sec. 4.8 Field joints – Welded and Non-Welded was added.
11. Sec. 4.5 Field Procedures was moved to Sec. 4.9.
12. Table 1 Properties of primer and coating section was modified to add profiling mastic.
13. Table 1 Properties with the cone penetration maximum was reduced from 0.98 in to 0.89 in.
14. Table 1 Tape Coating properties added breaking strength minimum.
15. The previous Table 2 requirement for microcrystalline wax or petrolatum content, by weight was combined into Table 1.
16. Previous Table 3 Prequalification Requirements of Tape was renamed to Table 2.
17. Table 4 was deleted since the item on thickness is covered in Sec.5.5.2 Primer coverage.
18. Sec. 5.5.3 Electrical continuity inspection was updated to include an item on repair of defects.
19. Sec. 6.2 Packaging and Shipping was revised for consistency with other steel pipe coating standards.
