Precision E27 Lamp Cap Gauge Set IEC 60061-3 DC53 Steel (58-60 HRC)
Product Overview:
This product is made from Japan DC53 steel with a Rockwell hardness of 58–60 HRC, and complies with IEC 60061-3 standards. It is designed for quality inspection of E27 screw-type lamp caps.
The structure and thread profiles (such as thread waveforms) are computer-calculated and optimized, then precision-machined using CNC equipment, resulting in high accuracy and a refined appearance. The material is a high-grade cemented carbide with excellent rust resistance for long-lasting durability.
Technical Parameters:
| No. | Name | Sheet | Purpose | Usage |
| 1 | E27 Lamp Cap “Go” Gauge | IEC 60061-3 7006-27B-1 | To check the maximum major diameter of the E27 lamp cap thread and the minimum length of the lamp cap on finished lamps. | a) Screw the lamp cap into the gauge. If it can be screwed in
smoothly, the lamp cap complies with the maximum thread diameter
requirement. b) When the lamp cap is fully screwed into the gauge, the contact surface of the lamp cap should be flush with or protrude slightly from surface X of the gauge. This indicates that the lamp cap meets the minimum length requirement. |
| 2 | E27 Lamp Cap“Not Go” Gauge | IEC 60061-3 7006-28A-1 | To check the minimum value of the major diameter d of the E27 lamp cap thread on finished lamps. | When the gauge is placed over the lamp cap thread by its own weight, the central contact point of the lamp cap must not protrude beyond surface X of the gauge. |
| 3 | E27S1 Lamp Cap “Go” Gauge | IEC 60061-3 7006-27C-1 | To check the maximum and minimum values of dimension S1 (i.e., solder height) on an E27 lamp cap. | Insert the lamp cap of the finished product into the gauge. The end face W of the gauge plunger should be flush with or protrude slightly from surface X, but it must not be higher than surface Y. |
| 4 | E27 Lamp Cap Contacting Making Gauge | IEC 60061-3 7006-50-1 | To check the contact performance of the lamp with a standard IEC lamp holder. | Push the tested lamp into the gauge. If it reaches surface W and makes contact with or goes beyond surface V, it indicates good contact performance. Otherwise, it does not meet the requirement. |
| 5 | E27 Lamp Cap Prevent Accidental Contact Gauge | IEC 60061-3 7006-51A-2 | To check the protection against accidental contact when inserting an E27 lamp cap into a finished lamp. | When the lamp is fully inserted into the gauge, if surface W does not protrude beyond surface V, the lamp shape is considered compliant with the protection against accidental contact requirement. |
| 6 | E27 Lamp Cap Prevent accidental contact gauge 51*39 | IEC 60061-3 7006-51-2 | To test the protection against accidental contact of the E27 lamp cap on finished lamps. | Push the lamp cap into the gauge as far as possible. Surface W must not protrude beyond surface V. If it does, the lamp fails the requirement. |
| 7 | E27 Lamp Cap Torque Test Gauge | IEC 60968 Fig2 | To test the mechanical strength of the lamp cap. | Gradually apply torque, increasing slowly until the specified torque is reached — 3 Nm for E27 lamp caps. |
