Product Description:
The IEC60061-3 E14 7006-55-2 is a standardized lamp gauge designed for E14 screw base bulbs, ensuring compatibility and precise fitting in a variety of lighting fixtures. This specification is part of the IEC 60061-3 international standard, which defines the dimensions, tolerances, and technical requirements for lamp caps and holders.
The E14 7006-55-2 designation indicates a specific thread size (14mm diameter) and gauge measurement, crucial for manufacturers and engineers to ensure proper electrical contact and mechanical stability. This lamp gauge is commonly used in small bulbs, decorative lighting, chandeliers, and appliances where a compact screw base is required.
Key Features:
Standard Compliance: Meets IEC60061-3 international standards for safety and performance.
Precision Engineering: Ensures secure fit and reliable electrical connection for E14 base bulbs.
Versatile Application: Ideal for LED bulbs, incandescent lamps, and decorative lighting.
Global Compatibility: Widely used in Europe, Asia, and other regions following IEC standards.
The IEC60061-3 E14 7006-55-2 is a protection-against-accidental-contact gauge built to sheet 7006-55-2 of IEC 60061-3. It verifies that live parts of the cap cannot be touched when the lamp is inserted into a holder. The E14 cap is an Edison screw with 14 mm nominal major thread diameter — small Edison screw (SES) caps used on candle, appliance and decorative lamps. Kingpo machines this gauge in-house from hardened tool steel, inspects it against the sheet before despatch and ships it with a calibration certificate, so it can go straight into an incoming-inspection or production-gauging routine.
What this gauge checks
- That no live part of the cap can be touched during insertion of the lamp
- The gauge planes specified on the sheet, read visually or with the specified feeler
The dimension that matters on a E14 cap is 14 mm nominal major thread diameter. It is what decides whether the lamp seats correctly and stays safe in the holder, and it is the geometry this gauge is built around.
Specification
| Standard | IEC 60061-3 (lamp caps, lampholders and gauges) |
| Sheet | 7006-55-2 |
| Cap type | E14 — Edison screw, 14 mm nominal major thread diameter |
| Gauge class | A protection-against-accidental-contact gauge |
| Purpose on the sheet | gauge for protection against accidental contact |
| Material | Hardened tool steel (stainless steel on request) |
| Calibration | Supplied with a calibration certificate; re-calibration available |
| Made by | Kingpo — machined, inspected and calibrated in-house |
How the test is run
- Bring the gauge and the lamp to ambient temperature.
- Push the lamp into the gauge as far as it will go.
- Read the gauge planes: the lamp plane must not protrude beyond the gauge plane.
- Record the result. This is a shape check, not a force check — no torque is applied.
The verdict is live parts must not be reachable when the lamp is inserted. Read the gauge, do not force it: a limit gauge that is forced into place tells you nothing about the part and damages the gauge.
GO and NOT GO — why you usually need both
A single limit gauge proves only one side of a tolerance. A GO gauge shows the part is not too small; a NOT GO gauge shows it is not too large. Running both is the only way to demonstrate a cap or a lampholder sits inside the band, and it is what an auditor will expect to see recorded. If you are building a gauge set from scratch, order the two together and keep them in the same case.
This gauge is not a GO / NOT GO pair on its own — it reads a specific feature. Pair it with the GO and NOT GO gauges of the same series when you need full dimensional coverage.
Getting the right sheet
IEC 60061-3 assigns one sheet number per gauge, and the number is what you should order against. Three things decide it: the cap family, whether you are checking a finished lamp or a lampholder, and which feature is being checked — thread, contact-making, protection against accidental contact, insertion torque or a named dimension. Sending us the sheet number avoids the most common error in this category, which is ordering a cap gauge when the test is on the holder, or the other way round.
Frequently asked questions
Is this gauge supplied with a calibration certificate?
Yes. Every Kingpo gauge is inspected against the sheet before despatch and shipped with a calibration certificate. We can also re-calibrate gauges you already hold.
Which lamps does the E14 version cover?
It covers E14 caps — 14 mm nominal major thread diameter. If your lamp uses a different cap family, the sheet number will be different; send us the cap marking and we will identify the sheet you need.
Can you make a gauge to a drawing instead of to a sheet number?
Yes. We machine to customer drawings as well as to IEC 60061-3 sheets, including modified gauges for production gauging where a full standard gauge is impractical.
What wears out on this type of gauge?
The gauging surfaces and any thread. Limit gauges are inspection tools, not production tools: keep them off the production line, store them dry, and re-calibrate on a cycle set by usage rather than by calendar.
