General 1.0 Description The rubber rings herein described consist of a properly vulcanized rubber of members of the MR" family. The "R" family is classified as "rubbers or elastomers having an unsaturated carbon chain; for example, natural rubber and synthetic rubbers derived at least partly from diolefins", as defined in ASTM Designation D 1418-61T. Natural rubber, natural rubber blended with synthetic elastomers, or syn thetic elastomers which will meet the requirements of this specification may be used. No reclaim or scrap rubber is permitted. Polymers that are not members of-the "R" family may also be considered, provided they perform the purpose intended and meet the requirements of this specification satisfactorily. 2.0 Design All rings shall be circular in form and cross section and shall be manufactured to the dimensions specified in Figure I of this specification. 3.0 Conformance The rubber rings as supplied under this specification shall also conform to the requirements of ASTM Specification D 1869, latest revision. B. Use Rubber rings as described in this specification are intended for use as an end plug for CPC Building Sewer Pipe, when used in con junction with plastic spacers. The rubber ring separates the plastic spacers which are connected by a bolt and wing nut.. When the wing nut is tightened, the spacers are drawn together causing the ring O.D. to enlarge, thts forming a seal. The end plugs are intended for use with Building Sewer Pipe as manufactured by the Mazza process only. FORM P92 7 8-62 TECHNICAL SPECIFICATIONS CERTAIN-TEED PRODUCTS CORPORATION ASBESTOS CEMENT PIPE NUMBER: 536 6UPERSSDEB: ^ y^ 5,/o/cv APPLICABLE TO: CLASSIFICATION: PAGE 2 orDATE ISSUE: 10 /c /'/ob Rubber Rings Purchasing Specification DESCRIPTION: Adaptor Rings For Use With Building Sewer End Plugs C.
