7006-24A-1 Gauge for Finished Lamps Fitted with E39 Caps for Testing Contact-Making

IEC60061-3 7006-24A-1 Gauge for Finished Lamps Fitted with E39 Caps for Testing Contact-Making

The plunger of the gauge is shown in the test position.

When the plunger is at rest, surface W shall be retracted deeper than surface V.

PURPOSE: 

To check lamp dimensions, particularly the combination of cap length and bulb shoulder shapes, for contact-making in a lampholder.

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 surface W reaches surface V or projects beyond it.

Note. - Some existing lamp designs employing G-shaped bulbs with short checks may not satisfy this gauge.
