6.1 General
Unless otherwise noted, the dimensions for socket- welding fitings given in Tables 4 and 11 and the dimensions for threaded fttings given in Tables 5, 6, 7, I2, I3, and I4 are nominal values and subject to the designated manufacturing tolerance.
6.3.1 Wall Thickness. The body or end wall thick- ness of threaded fttings shall be equal to or greater than the minimum values, G, as shown in Tables5, 6, I2, or I3.
6.3.2 Internal Threading. AIll fttings with internal threads shall be threaded with American National Stan- dard Taper Pipe Threads (ASME B 1.20.1). Variations in threading shall be limited to one turm large or one turn small from the gaging notch when using working gages. The reference point for gaging is the starting end of the fiting, providing the chamfer does not exceed the major diameter of the internal thread. When a chamfer on the internal thread exceeds this limit, the reference point becomes the last thread scratch on the chamfer cone.
6.3.3 External Threads. All externally threaded fitings shall be threaded with American National Stan- dard Taper Pipe Threads (ASME B1.20.1) and the variation in threading shall be limited to one turn large or one turn small from the gage face of ring when using working gages. The reference point for gaging is the end of the thread.
6.3.4 Countersink or Chamfer. All internal threads shall be countersunk a distance not less than onc- half the pitch of the thread at an angle of approximately45 deg with the axis of the thread, and all external threads shall be chamfered al an angle of 30deg to 45 deg from the axis, for the purpose of easier entrance in making a joint and for protection of the thread. Countersinking and chamfering shall be concentric with the threads. The length of threads specified inall tables shall be measured to include the coun- tersink or chamfer.
