E40 lamp cap gauge, IEC60061-3 gauges, go no go gauge, go and no go gauge
E40 Cap Gauge IEC60061-3 On Finished Lamps E screw thread gauge
E40 Lamp cap gauge list:
| 7006-27-7 | “GO” gauge for E40 caps on finished lamps |
| 7006-28D-1 | “NOT GO” gauge for E40 caps on finished lamps |
| 7006-52-1 | Gauge for finished lamps fitted with E40 caps for testing contact making |
| 7006-53-1 | Gauge for finished lamps fitted with E40 caps for testing protection against accidental contact |
Purpose and Testing:
(1) 7006-27-7
“GO” gauge for caps on finished lamp
PURPOSE:
To check the maximum dimensions of the screw thread and dimension T1 minimum of E40 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) 7006-28D-1
“NOT GO” gauge for caps on finished lamps
PURPOSE:
To check the minimum outside(major) diameter of the screw thread , dimensiion d, of E40 caps on finished lamps
TESTING:
a) 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
b) Only the weight of the gauge itself shall be used in the test.
(3) 7006-52-1
Gauge for finished lamps fitted with E40 caps for testing contact making
PURPOSE:
To check lamp dimensions for contac 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.
(4) 7006-53-1
Gauge for finished lamps fitted with E40 caps for testing protection against accidental contact
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, plan W does not protude beyond plan V
Confirms:
IEC60061-3
