1. Scope
1.1 This specification describes material and physical re- quirements for nonrigid poly (vinyl chloride) (PVC) preformed molded and spliced gaskets used in mechanical couplings. These couplings are used in gravity flow drain, waste, and vent (DWV), sewer, sanitary, and storm plumbing systems. They include couplings to join similar and dissimilar piping sizes and piping material. 1.2 It is acceptable to use recycled materials in this product in accordance with the requirements in Section 4. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. N OTE 1—There is no known ISO equivalent to this standard. 1.4 The following safety hazards caveat pertains only to the test method portion, Section 7, of this specification: This standard does not purport to address all ofthe safety concerns, ifany, associated with its use. It is the responsibility ofthe user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
6. Sampling
6.1 Sample using a statistically acceptable procedure. 6.2 A shift of production on a molding line shall be considered as a unit of manufacture for sampling purposes. 6.3 Spliced gasket production shall be sampled at a level of 100 % of total spliced units produced during the trimming and inspection operation.
7. Test Methods
7.1 Spliced Gasket Stretch Test—Gasket specimens shall be stretched during the seam trimming operation by inverting the spliced section 180°, while carefully inspecting the seam for separation and peeling and the seam area for workmanship imperfections (5.4.1). 7.2 The physical properties enumerated herein shall be determined on the non-rigid PVC compound in accordance with the following methods: 7.2.1 Test Specimens—Unless otherwise specified, test specimens shall be prepared of sheets 0.075 6 0.010 in. (1.9 6 0.2 mm) thick. Specimens shall be of the shape and dimensions specified in the individual test methods. 7.2.2 Conditioning—Test specimens of non-rigid PVC plas- tics shall be conditioned in accordance with Procedure A of Practice D618. 7.2.3 Unless otherwise specified, tests shall be conducted in the standard laboratory atmosphere of 23 6 2°C (73 6 4°F) and 50 6 10 % relative humidity. 7.2.4 Durometer Hardness—Test Method D2240 using a 15 s interval as described in 9.2 of that method. 7.2.5 Tensile Strength and Percent Elongation—Test Meth- ods D412, using specimens prepared with Die C. 7.2.6 Volatile Loss—Test Method D1203 using Method A, except that the test temperature shall be 105°C. 7.2.7 Brittleness Temperature—Test Method D746, using Procedure A. 7.2.8 Tear Strength—Test Method D624, using Die C. 7.2.9 Heat Aging—Test Method D573 for 96 h at 70 6 2ºC (158 6 4ºF).7.2.10 Water Absorption—Test Method D471 for 7 days at 70 6 2ºC (158 6 4ºF). 7.2.11 Ozone Resistance—Test Method D1149, using test specimen A for 100 h at 40 6 2ºC (104 6 4ºF) with ozone concentration of 1.5 ppm. 7.2.12 Oil Immersion—Test Method D471 for 70 h at 100 6 2ºC (212 6 4ºF). 7.2.13 Stress Relaxation—Test Method D6147, using Method B, and test specimen as defined in section 7.1.2 of D6147. The test temperature and duration shall be 168 h at 23 6 2ºC (73 6 4°F).
8. Certification
8.1 The gasket manufacturer shall keep appropriate produc- tion and testing records, including certification documentation from the PVC compound producer, required to certify, when requested by the purchaser, that the product meets all require- ments of this specification.
