Reaffirmed 2018

1 Scope

1.1 This standard covers the dimensions, for straight involutesplines of 30� pressure angle, with three differenttypes of fits, namely, major diameter fit, minor diameter fit andside fit.

1.2 Involute splines of modules (1), 1.25, (1.5), 2, (2.5), 3,(4), 5, (6), 8 and (10) are covered in this standard. The valuesgiven within brackets are non-preferred.
