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: L1 4.
Notes
No published standard: values are reconciled from makers' drawings (ADR 0034).
- = k not dimensioned by the drawings: the house flange t/6, min 1.5 mm (sheet DO2). Mounting holes run through t, through both flanges.
Rotor (bore, hub, struts, blades) is illustrative: sheet DO2.
