RTJ flanges measurements are shrouded in ASME B16.5 – which spreads Pipe Flanges and Flanged Fittings for size NPS ½" to 24" for above NPS 26" to 60" it ought to be according to ASME B16.47.
During a dimensional examination of RTJ flanges, you should check for External and Inner Diameter of body, Jolt Circle and Bolt opening Diameter, The thickness of the weld end, Length of the Hub, Straightness and arrangement of the jolting opening, RTJ Groove Dimensions.
