Purpose: 

To check the maximum dimensions of the screw thread and dimension T1 minimum of E14 caps on finished lamps.

Testing: 

When the cap on a finished lamp has been screwed into the gauge as far as it will go, the centre contact shall be co-planar with, or project beyond surface X.

 


2. Go gauge for dimension "S1" of E14 caps on finished lamps, 7006-27G-1;

Purpose: 

To check the dimensions S1 minimum and S1 maximum of E14 caps on finished lamps.

Testing: 

When the cap on a finished lamp has been screwed into the gauge as far as it will go, the plunger surface W shall be co-planer with or project beyond surface X but it shall not project beyond surface Y.

 


3. Not go gauge for E14 caps on finished lamps, 7006-28B-1;

Only the weight of the gauge itself shall be used in the test.

 


4. Gauge for finished lamps fitted with E14 caps for testing contact making, 7006-54-2;

Purpose: 

To check lamp dimensions for contact making in IEC holders.

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 till plane W reaches plane V or projects beyond it.

 


5. Gauge for finished lamps fitted with E14 caps for testing protection against accidental contact, 7006-55-2.

Purpose: 

To check protection against accidental contact.

Testing: 

The shape of the lamp with regard to protection against accidental contact is assumed to be correct if the test sample being pushed as far as possible into the gauge, plane W does not protrude beyond plane V.

The application of this gauge is restricted to the following lamps when they are fitted with E14 caps, in accordance with sheet 7004-23:

Candle lamps

Round bulb lamps

Domestic tubular lamps

Pygmy lamps.
