8.1.4 True Ys. Center-to-face dimensions for straight size true Ys are shown in Tables 3 and 5 (Tables I-3 and I-5). Reducing sizes are considered special and should be made to suit conditions.
8.1.5 Reducers and Eccentric Reducers. The face- to- face dimensions for all combinations of reducers and eccentric reducers shall be the same as given in Tables 3 and 5 (Tables I-3 and I-5) for the larger opening.
8.1.6 Interchangeability. Class 150 flanged fittings in NPS 1 and larger sizes have a bolting pattern that is dimensionally interchangeable with ASME B16.1, Class 125 Cast Iron Flanged Fittings; ASME B16.5, Class 150 Steel Flanged Fittings; and ASME B16.42, Class 150 Ductile Iron Flanged Fittings. Class 300 flanged fittings in NPS 1 and larger have a bolting pat- tern that is dimensionally interchangeable with ASME B16.1, Class 250 Cast Iron Flanged Fittings; ASME B16.5, Class 300 Steel Flanged Fittings; and ASME B16.42, Class 300 Ductile Iron Flanged Fittings.
8.2 Wall Thickness
For inspection purposes, the minimum wall thickness, t, of flanged fittings at the time of manufacture shall be as shown in Tables 3 and 5 (Tables I-3 and I-5), except as provided in para. 10.2. Additional metal thickness needed to withstand assembly stresses, shapes other than circular, and stress concentrations shall be deter- mined by the manufacturer. In particular, 45-deg laterals, true Ys, and crosses may require additional reinforce- ment to compensate for inherent weaknesses in these shapes.
10.1 Convention
For determining conformance with this Standard, the convention for fixing significant digits where limits (maximum and minimum values) are specified shall be as defined in ASTM E29. This requires that an observed or calculated value be rounded off to the nearest unit in the last right-hand digit used for expressing the limit. Decimal values and tolerances do not imply a particular method of measurement.
