E26d Lamp Cap Gauge IEC 60061-3 Description
E26d Lamp Cap Gauge Screw Thread Gauge iec 60061 3 With Calibration Certificate
The E26d Lamp Cap Gauge IEC 60061-3 for Screw Thread Testing on Finished Lamps is a precision Go/No-Go gauge manufactured by KingPo. It is designed to check the critical dimensions Cmax and C1max of E26d caps on finished lamps in accordance with IEC 60061-3 (7006-29D-1), ensuring dimensional compliance and proper fit for lamp safety and interchangeability.
Testing Principle
- When the unmounted E26d cap is pushed into the gauge as far as it will go, surface W of the plunger shall not project beyond surface X. For caps on finished lamps, surface W shall not project beyond surface V, with the cap positioned so that the solder on the intermediate contact is located in the recess provided in the gauge. This verifies that the screw thread dimensions meet the exact IEC 60061-3 requirements.
Professional Construction & Technical Precision
Key features include:
- Hardness steel construction for high-accuracy dimensional verification
- Go/No-Go design specifically for E26d caps on finished lamps (reference diameter 10.4 mm)
- Precise surface and plunger geometry per IEC 60061-3 Figure 7006-29D-1
- Calibration certificate supplied with every gauge for full traceability
-

To check dimensions Cmax. and C1max. of caps E26d.
These elements ensure accurate, repeatable and standard-compliant screw thread testing.
