ASTM D3139 Test Machine Joints for Plastic Pressure Pipes Using Flexible Elastomeric Seals  specification covers the two types of joints, mechanical joint and push-on-joint, required for plastic pipe pressure systems with a wall thickness equal to or greater than that of SDR 64 intended for use in supply and distribution lines for water using flexible elastomeric seals. The joint shall be designed to provide a permanent seal, with surfaces free of imperfections that could adversely affect its performance. Internal hydrostatic pressure and vacuum tests shall be conducted on the assembled joints under standard laboratory temperature and relative humidity conditions. The joint assemblies shall conform to the pressure rating, stiffness, and deflection requirements. This specification covers the types of joints required for plastic pipe pressure systems with a wall thickness equal to or greater than that of SDR 64 and intended for use in supply and distribution lines for water, using flexible elastomeric seals. This specification covers the test requirements, test method, and materials. The test methods described are not intended to be routine quality control tests but are to evaluate the performance characteristics of the joint.
