DIN VDE 0620-1 Lehre 3 Lehre für die Einführbarkeit zweipoliger Stecker

This DIN VDE 0620-1 Lehre 3 Lehre für die Einführbarkeit zweipoliger Stecker is a specialized gauge designed to verify the insertability of two-pole plugs into sockets, adhering strictly to the DIN VDE 0620-1 Lehre 3 standard. It ensures that sockets comply with relevant industry norms, guaranteeing smooth and secure insertion of plugs that meet specified dimensional requirements. By simulating the maximum pin dimensions of standard-compliant plugs, the gauge plays a critical role in pre-test validation and quality control of sockets, safeguarding user safety and product reliability in household and similar applications.

Specifications:
• Complies with DIN VDE 0620-1 (2021-02) “Plugs and sockets for household and similar purposes – Part 1: General requirements for fixed sockets” Lehre 3
• Compatible with sockets meeting DIN 49075, DIN 49440-1, DIN 49440-5, DIN 49440-6, DIN 49442, DIN 49445, DIN 49447 standards
• Pin diameter: ø4.84 +0.02 mm
• Key dimensional parameters: 23.88 +0.02 mm (relevant length), 14.12 -0.02 mm (relevant length)
• Pin surface roughness: Rz 5
• Angular specifications: 20° (as per dimensional drawings)
• Both pairs of pins on the gauge allow unrestricted and complete insertion into the tested socket

Test Procedures:
• Prepare a plug that complies with the applicable standard and has maximum pin dimensions, then insert and withdraw it into/from the socket 10 times prior to formal testing.
• Select the appropriate gauge (in conjunction with other specified gauges L1, L2, L4, L5, L8 if required) and follow the specified test sequence.
• Perform the test through measurement and/or direct use of the gauge, ensuring compliance with manufacturing tolerances as specified in the gauge drawings.
• Verify that both pairs of pins on the gauge can be inserted into the socket freely and completely without obstruction.

Applications:
• Quality control and pre-test validation of fixed sockets for household use and similar applications.
• Compliance testing of sockets to ensure adherence to DIN VDE 0620-1 Lehre 3 and related DIN series standards.
• R&D and production inspection processes for socket manufacturers to ensure plug insertability.
• Third-party testing laboratories conducting conformity assessments for electrical socket products.
