Source levels
Main value = the modeled value (nominal, else the middle of min-max).
Grey under a value = its min-max, where the source gives both.
< / = = the source gives only that limit, modeled at it. ref = reference.
L2 = the standard itself (or its complete free preview, or the maker's drawing). L1 = two or more independent sources agree: the release gate.
LO = one source only: printed amber and marked *.
c = a source value was corrected; the datasheet says how.
House convention = a detail no source dimensions, drawn to a stated house rule. This size's values: L11.
Notes
Dw: the nominal ball diameter, modeled as is. inch: Table 1's corresponding inch size, for reference only; - for a metric ball. Grade, gauge and tolerances are ordered with the ball, not modeled (sheet DO2).
