ASTM D3262:20 pdf download.Standard Specification for “Fiberglass” (Glass-Fiber-Reinforced Thermosetting-Resin) Sewer Pipe.
5.3 Liner and Surfiice Laver——A liner or surface layer, or both, when incoq)orated into or onto the pipe, shall meet the structural requirements of this specification.
5.4 Joints—The pipe shall have a joining system that shall provide for fluid tightness for the intended service condition. Restrained or unrestrained and flexible or rigid joints are acceptable depending on the specific configuration and design conditions.
5.4.1 Unrestrained—Pipe joints capable of’ withstanding internal pressure but not longitudinal tensile loads.
5.4.1.1 coupling or Bell-and-Spigot Gasket Joints, with a groove either on the spigot or in the bell to retain an elastomeric gasket that shall be the sole element of the joint to provide watertighiness. For typical joint detail see Fig. I.
5.4.1.2 Mechanical coupling Joint, with elastomeric seals.
5.4.1.3 Bun Joint, with laminated overlay.
5.4.1.4 Flanged Joint, both integral and loose ring.
5.4.2 Restrained- Pipe joints capable of withstanding internal pressure and longitudinal tensile loads.
5.4.2.1 Joints similar to those in 5.4. 1 . I with supplemental restraining elements.
5.4.2.2 Butt Joint, with laminated overlay.
5.4.2.3 Bell-and-Spigot, with laminated overlay.
5.4.2.4 Bell-and-Spigot, adhesive-bonded joint: Three types of adhesive-bonded joints are permitted by this standard as follows:
(1) Tapered hell-and-spigot, an adhesive joint that is manufactured with a tapered socket for use in conjunction with a tapered spigot and a suitable adhesive.
(2) Straight bell-and-spigot, an adhesive joint that is manufactured with an untapered socket for use in conjunction with an untapered spigot and a suitable adhesive.
(3) Japered bell and straighi spigot, an adhesive joint that is manufactured with a tapered socket for use with an untapered spigot and a suitable adhesive.
5.4.2.5 Flanged Joint, both integral and loose ring.
5.4.2.6 Mechanical coupling, an elastomeric sealed coupling with supplemental restraining elements.
5.4.2.7 Threaded joints.
NOTE 6— It is acceptable to add other types of joints as they become commercially available.
NOTE 7— -Restrained joints typically increase service loads on the pipe to greater than those experienced with unrestrained joints. The purchaser is cautioned to take into consideration all conditions in the anticipated service and to consult the manufacturer regarding the suitability of a particular type and class of pipe for service with restrained joint systems.
5.5 Gaskets—Elastomeric gaskets used with this pipe shall conform to the requirements of Specification F477, except that composition of the elastomer shall be as agreed upon between the purchaser and the supplier for the particular exposure to oily or aggressive chemical environments.
