| 7<\/td>\n | Foreword I.\tIntroduction. I.A.\tBackground.\u2003This standard describes bolted, split-sleeve couplings used to join pipe. It also includes materials of construction, inspection, and testing. These couplings have been used on water pipe since 1981. I.B.\tHistory.\u2003In October 1999, the AWWA Standards Council authorized the AWWA Standards Committee for Steel Pipe to develop a new standard for the use of bolted, split-sleeve couplings for plain-end pipe. The first edition of that standard was approved by I.C.\tAcceptance.\u2003In 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 <\/td>\n<\/tr>\n | ||||||
| 8<\/td>\n | II.\tSpecial Issues. II.A.\tAdvisory Information on Product Application.\u2003Although details differ, all couplings of this type work in a similar fashion and have similar components as depicted in the standard. Coupling manufacturers should be contacted for detailed design inform II.B.\tChlorine and Chloramine Degradation of Elastomers.\u2003The 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.

| 9<\/td>\n | II.B.1.\tGasket Degradation Study.\u2003A 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, III.\tUse of This Standard.\u2003It 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.
