Minimum space recommended for thru-hole, pad to pad

In the IPC-SM-782 (Surface Mount Design and Land Pattern Standard) it recommends a minimum of .040" between bottomside wavesoldered chip pads.

Where might I find a similar IPC recommendation for minimum space between thru-hole pads?

Does anyone know what it is?

Even though you may find a pad-pad thru-hole spacing, part body size, orientation, and insertion head tooling clearences may be the deciding factor in spacing.

1. Part body diameter will dictate component centroid spacing.

2. Tooling head clearences for automation will dictate lead to lead.
