IEC 60884-1 Annex B Plug Gripping Test Device With Reference Plug

The LS-B18 Plug Gripping Test Device With Reference Plug is a precision-engineered testing apparatus specifically designed for the quantitative evaluation of plug clamping performance in accordance with international and national standards. This device employs calibrated clamping mechanisms to securely fix test specimens, integrating with certified measurement instrumentation to collect and analyze force data under controlled conditions. The system simulates operational stress states encountered during actual plug usage scenarios, enabling standardized verification of clamping force retention capabilities.

Through rigorous adherence to standardized test protocols, this device generates accurate, repeatable measurement data to validate compliance with technical requirements specified in applicable standards. This ensures that tested products meet established safety and performance criteria for electrical connectivity.

Standardized Test Procedure

1. Test Specimen Preparation: Secure the test plug within the sample fixture, ensuring the plug surface is flush with the plate’s bottom surface. Insert the test plug pins through the designated plate holes, then pass the alignment rod through all plug pin holes. Attach the digital force gauge to the top ring assembly.
2. Force Measurement – Test Plug: Apply controlled tensile force via the digital force gauge and record three consecutive force measurements following standardized pull procedures.
3. Reference Plug Testing: Secure the certified reference plug within the sample fixture, ensuring surface flush alignment. Pass the alignment rod through the reference plug hole, attach the digital force gauge to the top ring assembly.
4. Force Measurement – Reference Plug: Apply controlled tensile force via the digital force gauge and record three consecutive force measurements following standardized pull procedures.
5. Data Analysis: Compare force values obtained from test plug measurements (Step 2) with reference plug measurements (Step 4) in accordance with IEC 60884-1 Annex B requirements and IEC 60884-1 Figure B.1 specifications.
