The drawing is intended only to illustrate the essential dimensions of the gauge.
For details of base MR11, see sheet 7004-108.
PURPOSE: To check the base MR11 in the following respects:
-the diameter of the individual pins (dimension E);
-the combined displacement and diameter of the pins (dimensions D and E);
-the length of the pins (dimension F);
-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 contact with surface Q of the gauge.
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.
