Gauges R, Rc/Rp Standards Pipe threads where pressure tight joint are made on the threads according to PN-EN 10226-1, pN-EN 10226-2 (IsO7-1:2000). Verification by means of limit gauges according to PN-EN 10226-3 (ISO-7-2:2000) 5.2.2. Design of gauges Gauge No. 1 Gauge No. 2 Gauge No. 3 Gauge No. 4 Gauge No. 5 Gauge No. 6 Taper full form threaded plug gauge. This gauge is a 1:16 taper full form threaded plug gauge and is suitable for checking the major diameter (D) and pitch diameter (D2) at the gauge plane of internal parallel (Rp) threads and internal taper (Rc) threads. Taper full form threaded plug gauge with relief. This gauge is a 1:16 taper full form threaded plug gauge with relief of threads and is suitable for checking the major diameter (D) and pitch diameter (D2) at the gauge plane, and the accomodation lenght of inernal parallel (Rp) threads and internal taper (Rc) threads. 1 Accomodation lenght: distance from the face of an internally threaded workpiece to the first obstruction which the externally threaded workpiece will encounter on assembly. Parallel full form threaded ring gauge. This gauge is parallel full form threaded ring gauge and is suitable for checking the minor diameter (d,) and pitch diameter (d2) at the gauge plane of taper external (R) threads. Taper plane ring gauge. This gauge is a 1:16 taper plain ring gauge and is suitable for checking the major diameter (d) and the related useful thread lenght on taper external (R) threads. Taper modified thread form check plug gauge This check plug gauge is used to check the dimensions of the parallel threaded ring gauge (gauge No. 3) when manufacturing the ring gauge and for checking the ring gauge for wear. Parallel modified thread form check ring gauge This check ring gauge is provided to check the dimensions of the taper full form threaded plug gauges (gauge Nos. 1 and 2) when manufacturing the plug gauges and for checking the plug gauges for wear Q 296 TECHNICAL INFORMATION 5.2.
