DIN VDE 0620-1 Lehre 19a Gauge for Testing Force Required to Open Shutter for Sockets 16 A, 250 V

DIN VDE 0620-1 Lehre 19a Gauge for Testing Force Required to Open Shutter for Sockets 16 A, 250 V is a precision-engineered testing instrument designed to measure the force required to open the protective shutters on 16 A, 250 V electrical sockets. This gauge strictly complies with the requirements specified in DIN VDE 0620-1:2010 (Lehre 19a) and DIN 49440-1 standards for socket safety testing.

It features a movable design that allows full insertion by its own weight, with rounded edges and stable structural performance to ensure accurate and reliable force measurement for socket shutter compliance verification.

Specifications:

• Applicable standards: DIN VDE 0620-1 Lehre 19a, DIN 49440-1
• Rated parameters: 16 A, 250 V
• Core function: Testing the force required to open socket shutters
• Design feature: Movable structure, fully insertable by its own weight
• Edge treatment: Slightly rounded
• Dimension adjustment: Allowable extension of dimension “a” up to 9.0 mm if the shutter cannot be fully opened (per standard provisions)
• Manufacturing requirement: Strictly fabricated in accordance with DIN VDE 0620-1 relevant specifications

Test Procedures:

1. Inspect the gauge for cleanliness, no visible damage, and confirm its movable structure functions smoothly before use.
2. Secure the 16 A, 250 V socket under test in a stable, horizontal fixture to avoid position deviation.
3. Align the gauge with the socket’s shutter opening position as specified in DIN VDE 0620-1 Lehre 19a.
4. Allow the gauge to insert fully into the socket by its own weight without applying additional external force.
5. Measure and record the force required to open the socket shutter during the insertion process.
6. Verify if the measured force and shutter opening performance meet the acceptance criteria outlined in DIN VDE 0620-1 and DIN 49440-1.

Applications:

• Force measurement for opening shutters of 16 A, 250 V sockets to ensure compliance with DIN VDE 0620-1:2010 standards.
• Quality control in the manufacturing process of household and similar application sockets.
• Conformity testing for socket safety in accordance with international electrical standards.
