IEC60061-3

The IEC60061-3 is an IEC 60061-3 limit gauge built to IEC 60061-3. 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

• The dimension or feature named on the sheet
• That the part falls inside the tolerance band the sheet defines

Specification

How the test is run

1. Condition the gauge and the sample together at ambient temperature.
2. Run the GO gauge first. It must enter freely under the gauge weight alone.
3. Run the NOT GO gauge. It must not pass the limit feature.
4. Both results together are the verdict — a single gauge never proves a thread.

The verdict is the sample must meet the limit on the sheet. 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.

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.
