ASTM A1045:17 pdf download.Standard Specification for Flexible Poly (VinyI Chloride) (PVC) Gaskets used in Connection of Vitreous China Plumbing Fixtures to Sanitary Drainage Systems.
5.2 Gaskets shall be tested in accordance with Section 9 on pipe samples complying with applicable industry standards of maximum and minimum dimensions. It shall be permissible to machine pipe samples to attain maximum or minimum dimensions, or both.
5.3 The gasket assembly when tested in accordance with Section 9 shall not leak.
5.4 The gasket shall accommodate vitreous china plumbing fixtures and flanges conforming to applicable industry standards.
6. Dimensions, Mass, and Permissible Variations
6.1 Gaskets shall conform to the dimensions and dimensional tolerances as agreed upon between the supplier and purchaser. All dimensions shall be compatible with the dimensions and tolerances of the specific pipe materials and sizes and vitreous china plumbing fixture to which it is designed to join.
7. Workmanship, Finish, and Appearance
7.1 The surface of preformed gaskets shall be smooth and free from pitting, cracks, blisters, air marks, or any other imperfections that may affect product performance in service.
7.2 Neither the flash thickness nor the flash extension shall exceed I/i, in. (1 mm).
7.3 Mold release, oil, or grease used in the manufacturing process will have a detrimental effect on the ability of the adhesive to adhere to the flanged surface of the fixture gasket. Care should be taken not to contaminate the flanged surface of the gasket.
8. Sampling, Tests, and Retests
8.1 Test specimens representative of the gaskets to he used shall be randomly selected from the manufactured lot for testing. The manufactured lot shall be a minimum of eight hours old. Tests shall be performed at room temperature.
.2 Where there is a failure in the original test, the entire test shall he rerun with twice the number of samples and any failure shall he cause for rejection.
9. Test Method for Assembled Gaskets
9.1 Test Apparatus—The apparatus used to conduct this test shall be designed according to the applicable outlet dimensions of the vitreous china plumbing fixture. See Fig. 1 for example.
The test apparatus shall be constructed of clear acrylic with a polished finish.
9.2 Significance and Use—This test method is useful in determining the ability of the gasket assembly to provide a permanent seal against water, sewer, sewer gas, and the like in vitreous china plumbing fixture to sanitary drain line connections.
93 Hazards—This is a pressurized hydrostatic test and under no circumstances shall water be substituted with air. Care should bc taken in expelling all air prior to pressurizing the test assembly. Wear eye protection during pressure tests and strictly adhere to safety precautions at all times.
9.4 Procedure— Hydrostatic Joint Tightness Test: Wipe the surface of the test apparatus with denatured alcohol. Apply the gasket assembly to the test apparatus. Insert the test apparatus assembly into the test pipe providing an adequate space between the test apparatus and the flange to prohibit compression of the gasket between the test apparatus and flange. Securely tighten the test apparatus to the flange, fill the assembly with water expelling all air, pressurize to 4.3 psi for a period of 15 miii. Any leakage shall result in failure. Refer to Fig. 2.
