E27 Caps Gauges Instructions

Related gauges for E27 caps:

1. Go gauge for E27 caps on finished lamps, code 7006-27B-1;

Purpose: 

To check the maximum dimensions of the screw thread and dimension T1 minimum of caps on finished lamps shown on sheet 7006-21.

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 E27 caps on finished lamps, code 7006-27C-1;

Purpose: 

To check the dimension S1 minimum and S1 maximum of E27 caps on finished lamps shown on sheet 7004-21.

Testing: 

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

 

3. Not go gauge for E27 caps on finished lamps, code 7006-28A-1;  

Purpose: 

To check the minimum outside (major) diameter of the screw thread, dimension "d" of E27 caps on finished lamps shown on sheet 7006-21.

Testing: 

When the gauge is placed over the thread of the cap on a finished lamp, held cap uppermost, the centre contact shall not project beyond surface "X".

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

 

4. Gauge for finished lamps fitted with E27 caps for testing contact making, code 7006-50-1;

Purpose: 

To check lamp dimensions for contact making in I.E.C. 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 E27/51x39 caps on finished lamps for testing protect against accidental contact, code 7006-51-2;  

Purpose: 

To check protection against accidental contact of caps E27/51x39 on finished lamps.

Testing: 

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

 

6. Gauge for E27 caps on finished lamps for testing protect against accidental contact during insertion, code 7006-51A-2.

Purpose: 

To check protection against accidental contact of caps E27 on finished lamps.

Testing: 

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