Go and not go gauge for unmounted bi-pin cap(not for use on finished lamps) G13, 7006-44-4

Go and not go gauge for unmounted bi-pin cap(not for use on finished lamps) G13, 7006-44-4

Purpose:

To check dimensions E min., E max., F min., G max., H max. and the combined pin diameter and displacement of pins (including bosses) of unmounted bi-pin caps G13.

Testing:

The pins of the cap shall enter the gauge at surface O and, when fully inserted, the surface of cap and gauge shall contact. In this position the ends of the pins shall be co-planar with or project beyond surface X. Each individual pin shall enter the hole e2 until the boss of the pin and the surface of the gauge contact, but they shall not enter hole e1. The boss of the individual pin shall enter hole b at surface O until the surfaces of the cap and the gauge contact.
