BS1363-1 Figure 33 Torsion Test Apparatus for Plug Pins

This BS1363-1 Figure 33 Torsion Test Apparatus for Plug Pins is a precision-engineered testing instrument designed for compliance with BS 1363-1 Figure 33 requirements. It performs standardized torsion testing on 13 A rewirable and non-rewirable fused plug pins to evaluate torsional strength and structural integrity.

The apparatus features a precision-machined structure including a plug clamp, dedicated plug engagement face, and a torque tube specifically adapted to match plug pin specifications, ensuring accurate and consistent torque application during testing. The system delivers reliable test conditions that simulate real-world mechanical stress on plug pins, making it an essential instrument for verifying product compliance with international electrical safety standards including BS 1363-1, supporting quality control and certification processes in the electrical accessory industry.
