Anotácia

This 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.
