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 Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.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, application, and field-procedure requirements for protective exterior coatings consisting of heat-shrinkable cross-linked polyolefin coatings.

MAJOR REVISIONS
1. Sec. III.A Purchaser Options and Alternatives, added #18 Frequency of Adhesion Testing 2. Added a new Sec. 1.1.3 to the Scope for substrates other than carbon steel.
3. In Sec. 3: Definitions Applicator was added.
4. Sec. 4 Headings were revised to be consistent with AWWA standardized wording and headings.
5. Sec. 4.1 Equipment was revised to be consistent with the updated wording in other steel pipe coating standards.
6. 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.
7. Sec. 4.3.1 the description of adhesive was expanded.
8. Sec. 4.4 Surface preparation was revised to establish consistent language between similar AWWA steel pipe coating standards and redundant language that is already included in the referenced SSPC standards was removed. References to SSPC-SP COM, SSPC-VIS 1, and SSPC-VIS 3 were also added to clarify when more thorough cleaning may be needed and which cleaning methods are considered more thorough.
9. The visual comparative standard section (old Sec. 4.3.2.3) was removed because it is duplicative with the language in the referenced SSPC SP standards in Sec. 4.4.3.
10. Sec. 4.6 Coating Repair was added.
11. In Sec. 5.2.10 updated the heading to Tensile strength at break and updated the heading of Sec. 5.2.11 to Elongation at break.
12. In Table 1 changed the units for Adhesion to prepared steel and Impact resistance values. In Table 2 changed the units for Field adhesion to prepared steel value.
13. Sec. 5.5.4.4, updated the frequency of the field peel test.
14. Sec. 6.3 was modified to include affidavits from both the coating manufacturer and the applicator.
