mismatch and are measured at the parting line. Mold flash or protrusions shall not exceed 0.20 mm per
side.
15. Dimension “b” does not include dambar protrusion/intrusion. Allowable dambar protrusion shall be
0.13 mm total in excess of “b” dimension at maximum material condition. Dambar intrusion shall not
reduce dimension “b” by more than 0.07 mm at least material condition.
