ANSI B92.1 Table 38 details the specifications for 30-degree pressure angle, fillet root side fit involute splines, providing crucial design data for pitch diameters, tolerances, and root radii in fatigue-critical, high-torque applications. It covers inch-series diametral pitches, typically ranging from 2.5/5 to 48/96, focusing on ensuring proper interchangeability through effective fit concepts.

You need to know the pin diameter for over-pin measurement. The formula and reference tables reside on page 38 of ANSI B92.1. Without that data, you cannot QC the part.
The standard covers:
Purchase from ANSI or ASME: The most direct ways to obtain the standard are through the ANSI or ASME websites. You can purchase the standard directly from these sources.

Interchangeability: This approach ensures that mating splines are interchangeable regardless of their individual tolerance classes, which is a significant advantage when one member is harder to produce than its mate. Inspection and Data Tables
