DIN VDE 0620-1 Gauge 15: Non-Accessibility Test Gauge for Socket Shutters After Operation Testing

This DIN VDE 0620-1 Gauge 15: Non-Accessibility Test Gauge for Socket Shutters After Operation Testing is engineered to verify the non-accessibility of live parts through the shutters of electrical sockets following normal operation testing, in strict compliance with the DIN VDE 0620 series standards. It serves as an essential safety verification instrument for fixed sockets deployed in residential and similar environments, ensuring that the protective shutter mechanism maintains its integrity after simulated operational cycles, thereby preventing unintended contact with live components and mitigating electrical shock hazards.

Specifications:

• Complies with DIN VDE 0620-1 and DIN VDE 0620-2-1:2021-02 standards
• Material: Rigid steel wire (Starrer Stahldraht)
• Dimensions: ø50, ø30, 3+0.03
• Length specification: 60mm
• Radius specification: R=0.2±0.05
• Calibration force: 20 N applied along the axis of the rigid steel wire
• Force requirement: Minimum 20 N must be maintained during testing
• Reference planes: A-A’ and B-B’ (for calibration alignment)

Test Procedures:

1. First, perform normal operation testing on the socket under test in accordance with relevant standard requirements to simulate real-world usage conditions.
2. Calibrate the gauge: Apply a 20 N force along the axis of the rigid steel wire to ensure the A-A’ plane aligns practically with the B-B’ plane, confirming the inner spring’s characteristic meets specifications.
3. Prepare the post-operation socket, ensuring it is in a stable state without obvious damage or deformation.
4. Position the calibrated gauge correctly relative to the socket’s shutters as per standard guidelines.
5. Apply a force of at least 20 N to the gauge during the test, adhering to the force requirement.
6. Attempt to access the socket’s live parts through the shutters using the gauge.
7. Record the test result; the socket passes if no access to live parts is achieved.

Applications:

• Post-operation safety verification of fixed…
