10.10 1.Datum plane –H– is located at bottom of lead and is coincident
with the lead where the lead exits the plastic body at the bottom of
the parting line.
2.Datums A–B and –D to be determined at datum plane –H–.
3.Dimensions S and V to be determined at seating plane –C–.
4.Dimensions A and B do not include mould protrusion. Allowable
mould protrusion is 0.25mm per side. Dimensions A and B do
include mould mismatch and are determined at datum plane –H–.
5.Dimension D does not include dambar protrusion. Allowable
dambar protrusion shall be 0.08 total in excess of the D dimension
at maximum material condition. Dambar cannot be located on the
lower radius or the foot.
6.Dimensions and tolerancing per ANSI Y 14.5M, 1982.
