Gauge for testing contact-making of lamps fitted with caps E26/25 7006-29-3

Gauge for testing contact-making of lamps fitted with caps E26/25 7006-29-3 

Purpose: 

To check lamp dimensions for contact-making in E26, E26/50x39, E26/51x39 or E26d lampholders. 

Testing: 

The shape of the lamp with regard to the fit in the lampholder is assumed to be correct, if the lamp can be pushed into the gauge until plane W reaches plane V or projects beyond it. For E26/24 capped lamps, when surfaces V and W are coincident, the top of the cap including any solder or conductive material, shall not extend above surface X.
