6.1 For the purpose of this Standard the following definitions shall apply
6.2 FITTING. RUBBER GASKETED — A device used to join pipes, fittings. and valves and uses an elastonieric material to seal the joint.
6.3 FLEXIBLE FITTING, RUBBER GASKETED - A rubber gasketed fitting. wtiicti allows axial displacemeni rotation and at least 1 degree of angular movement of the pipe without damage to the pipe for nominal pipe diameters of smaller than 203.2 mm (8 inches) or which allows axial displacement, rotation and at least 0.5 degrees of angular movement of the pipe without damage to the pipe for nominal pipe diameters of 203.2 mm (8 inches) and larger. These fittings are intended for installations where protection of piping against damage in areas where subject to earthquakes as required in NFPA 13.
6.4 PROPRIETARY GROOVES — Dimensions of the grooved end of pipe, fittings or valves specified by the rubber gasketed fitting manufacturer that differ by dimension or geometry from Standard Groove Dimensions. Products utilizing proprietary grooves are intended for use with specific rubber gasketed fittings that are compatible with the proprietary grooves.
6.5 STANDARD GROOVES - Dimensions of the grooved end of pipe, fittings. or valves that are considered standardized in the industry. Section 6.3 contains the requirements for determining dimensional compatibility of a rubber-gasketed fitting for use with standard grooves.
