34、kable cross-linked polyolefin coatings for external use on special sections, connections, and fittings for underground steel water pipelines have been used since 1960. This standard establishes required performance standards for heat-shrinkable cross-linked polyolefin coatings. I.B. History. The fir

35、st edition of this standard was approved by the AWWA Board of Directors on Jan. 29, 1989, and had an effective date of July 1, 1989. The second edition was approved on June 19, 1994, with an effective date of Aug. 1, 1995. The third edition was approved on Jan. 23, 2000. The fourth edition was appro

36、ved on Jan. 21, 2007. This edition was approved on Jan. 24, 2015. II. Special Issues. II.A. General. ANSI/AWWA C216 is intended to govern the exterior coating of special sections, connections, and fittings for steel water pipelines for underground or underwater installation under normal conditions.

37、ANSI/AWWA C216 is based on the best-known experience, but it is not intended for unqualified use under all conditions. The advisability of its use for any installation must be reviewed by the purchaser. II.B. Weld-After-Backfill. Weld-after-backfill is the sequence of assembling a welded joint, weld

38、ing the outside joint (if required), applying the exterior joint coating(s), backfilling the pipe joint, and then welding the inside joint at a later time (where internal welding is safe and practical). Weld-after-backfill is an acceptable practice provided that the requirements of all applicable AW

39、WA standards are followed. Consult with the manufacturers and other responsible parties regarding recommended products, installation and backfill procedures required for the weld- after-backfill sequence. At the request of the purchaser, the coating manufacturer shall provide testing or historical i

40、nformation to verify that the exterior joint coating will retain minimum performance requirements in accordance with the applicable standard throughout the heat-affected area. III. Use of This Standard. It is the responsibility of the user of an AWWA standard to determine that the products described

41、 in that standard are suitable for use in the particular application being considered. * American National Standards Institute, 25 West 43rd Street, Fourth Floor, New York, NY 10036.

42、e following items should be included by the purchaser: 1. Standard usedthat is, ANSI/AWWA C216, Heat-Shrinkable Cross- Linked Polyolefin Coatings for Steel Water Pipe and Fittings, of latest revision. 2. Whether compliance with NSF/ANSI 61, Drinking Water System ComponentsHealth Effects, is required

43、. 3. Any exceptions to the standard that may be required. 4. Description and number of each type of special sections, connections, and fittings for type of exterior protection. 5. Underground or underwater conditions. 6. Severe conditions (Sec. 1.1.1). 7. Maximum operating potable water temperature

44、of the pipeline (Sec. 1.1.2). 8. Configuration of coating (types I, II, III, and IV) (Sec. 4.2.1.1). 9. Coating dimensions (Sec. 4.2.1.3). 10. Thickness (Sec. 4.2.1.4). 11. Surface preparation (Sec. 4.3.2). 12. Visual comparative standard (Sec. 4.3.2.3). 13. Filler material (Sec. 4.3.3.3). 14. Train

45、ing (Sec. 4.3.3.5). 15. Repair (Sec. 4.3.4). 16. Conditions for outdoor storage (Sec. 4.3.5). 17. Prequalification (Sec. 5.1). Note : With reference to Sec. 5.1 (option 2), when submission of samples of proposed materials for testing by the purchaser is speci- fied, the purchaser should address how

46、testing costs will be assigned. According to commonly accepted industry practice, the purchaser is responsible for the cost of initial testing of coating material samples originally offered by the constructor. If any initial samples fail to conform to the standard, additional samples may be tested.

47、The con- structor pays for any additional testing. 18. Coating materials tests (Sec. 5.2). 19. Packaging (Sec. 6.2.1). 20. Affidavit of compliance if required (Sec. 6.3). III.B. Modification to Standard. Any modification to the provisions, definitions, or terminology in this standard must be provide

48、d by the purchaser. Copyright 2015 American Water Works Association. All Rights Reserved. xi I V. Major Revisions. Major changes made to the standard in this edition are as follows: 1. The title of the standard was changed to be consistent with other AWWA steel pipe coating standards. 2. Definitions

49、 for potable water and supplier were added (Section 3). 3. Previous Sec. 4.1, Permeation, was deleted to be consistent with other coat- ing and lining standards. This is an item that should be evaluated at the pipe or gasket design level. 4. New Table 2 was added: Quality Control Requirements of Applied Coating System. 5. Sec. 4.3.2.2, Cleaning, was revised, and previous Sec. 4.4.2.3, Abrasive Blast Cleaning, was deleted, to clarify the intent of the surface preparation section. 6. Sec. 4.3.3.3, Filler Material, was revised with additional information
