In May 1985, the US Environmental Protection Agency (USEPA) entered into a cooperative agreement with a consortium led by NSF International (NSF) to develop voluntary third-party consensus standards and a certification program for direct |
| 10 | II. Special Issues. II.A. Chlorine and Chloramine Degradation of Elastomers. The selection of materials is critical for water service and distribution piping in locations where there is a possibility that elastomers will be in contact with chlorine or chloramines. Documented |
| 11 | II.B. Gasket Degradation Study. A pipe gasket, having the hardness of a compressed elastomer with a large mass relative to the small exposed surface area, experiences minimal degradation. This was validated in a research paper reported in Journal AWWA , w III. Use of This Standard. It is the responsibility of the user of an AWWA standard to determine that the products described in that standard are suitable for use in the particular application being considered. III.A. Purchaser Options and Alternatives. The following information should be provided by the purchaser. |
| 12 | III.B. Purchaser’s Proof Test. The purchaser may specify individual hydrostatic proof testing. If individual hydrostatic proof testing is required, the assembled fabricated tapping sleeve shall be shop tested at a maximum of 1.5 times the working pressure III.C. Modification to Standard.
