DIN VDE 0620-1 Lehre 10a Single-Pole Insertion Impossibility Test Gauge
Leave a Message
This DIN VDE 0620-1 Lehre 10a Single-Pole Insertion Impossibility Test Gauge is engineered to meet the requirements of Lehre 10a in the DIN VDE 0620-1 standard (“Plugs and Sockets for Household and Similar Applications – Part 1: General Requirements for Fixed Sockets”) and is also aligned with DIN VDE 0620-2-1 (2021-02). Its core function is to test the “impossibility of single-pole insertion” in fixed sockets—a critical safety feature that prevents accidental insertion of a single electrical pole (which could expose users to live components and electrical shock hazards). With precise dimensional and angular design, the gauge ensures accurate validation of a socket’s anti-single-pole-insertion mechanism, making it an essential tool for manufacturers, testing laboratories, and quality assurance teams committed to adhering to DIN VDE safety standards for household and similar sockets.
Specifications:
- Complies with DIN VDE 0620-1 standard, specifically designed for Lehre 10a (testing the impossibility of single-pole insertion)
- Aligns with the technical requirements of DIN VDE 0620-2-1 (2021-02) to ensure up-to-date compliance
- Features a critical angular specification of 90° ± 2’30” (90 degrees plus or minus 2 minutes and 30 seconds), ensuring proper simulation of single-pole insertion attempts
- Incorporates two key diameter (ø) parameters, both specified as 4.8 mm with a tolerance of ±0.02 mm, to match the dimensional constraints of socket pole openings
- Includes a length dimension of 16.6 mm with a tolerance of ±0.1 mm, ensuring the gauge interacts with the socket’s internal safety mechanism as intended
- Core purpose: Verifies that fixed sockets block the insertion of the gauge (simulating single-pole access) to prevent electrical safety risks
Test Procedures:
- Prepare the fixed socket sample for testing, ensuring it is free from visible damage, assembled correctly according to product specifications, and meets pre-test conditions outlined in DIN VDE … (truncated)
