-the allowable build-up of cement within dimension W.
TESTING: It shall be possible to insert each individual pin of the base into
the hole e1 until surface Q of the base touches surface R of the
gauge.
It shall no be possible to insert each individual pin into hole e2.
It shall be possible to insert both pins simultaneously into the
holes e.
It shall be possible to insert the base into the gauge with the
pins entering at surface Q until surface Q of the base is in

In this position, the ends of the pins shall be co-planar with or
project beyond surface X but shall not project beyond surface Y.
NOTE - If, in addition, the base complies with the "Go" gauge for bi-pin lamp bases GZ4 (see sheet 7006-67), then the lamp can be used in GZ4 connectors as well.
