These are PVC , , , , and Fittings tested in accordance with 8. The burst pressure shall be used only as an indication of quality. Workmanship, Finish, and Appearance 7. The fittings shall be as uniform as commercially practicable in color, opacity, density, and other physical properties.
NOTE 3Mechanical strength, heat resistance, flammability, and chemical resistance requirements are covered in Specification D Test Methods 8. Requirements Requirements 6. The transition from D to DJ Table 3 shall be straight, tapered as shown, or radiused.
A positive taper in the same direction of the taper in the socket on the outside diameter of the bushing is optional. For any threaded fitting the minimum wall thickness of the threaded portion shall be at least equal to the thickness of material under the thread root of threaded Schedule 80 pipe of the same size.
Any fitting having a male thread shall have an internal diameter not larger than Schedule 80 pipe of the same size. NOTE 4For individual orders or specifications, only those tests and numbers of tests specifically agreed upon between the purchaser and the seller need be conducted. The pressure shall be applied at a uniform rate such that the minimum allowable burst pressure is attained in 60 or 70 s. NOTE 5The time-to-failure may exceed 70 s. A Nominal.
