     5.2.2. Design of gauges

     Gauge No. 1                          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.

     Gauge No. 2                          Taper full form threaded plug gauge with relief.

                                   f—f L  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.

     Gauge No. 3                          1Accomodation lenght: distance from the face o f 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.

                     Gauge No. 4          Taper plane ring gauge.
                                          This gauge is a 1:16 taper plain ring gauge and is suitable for checking
             0                            the major diameter (d) and the related useful thread lenght on
                     Gauge No. 5          taper external (R) threads.

     m                                    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.

     Gauge No. 6

                                          Parallel modified thread form check ring gauge

                                          This check ring gauge is provided to check the dimensions of the taper
