Source levels Main value = the modeled value (nominal, else the middle of min-max). Qa = 12.95°* Grey under a value = its min-max, where the source gives both. pD=40 < / = = 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: L18 - LO 2.
Notes
211, r3: the sources give r_s min only; modeled at that limit.
d1 (=, one source) and a (from Y by a cited rule) are LO: amber.
The cup wall, ribs, raceway and corners are house conventions, sheet DO2.
d1 = 29 ref*
