Test Pin of BS 1363-1 Figure

Test Pin of BS 1363-1 Figure is a dedicated safety tool designed to verify protection against access to hazardous live parts in plugs, socket-outlets, and adapters for the UK market. Compliant with Clause 9 BS 1363-1 Figure 1, it features a 1mm diameter steel pin (20mm long) for accessing narrow gaps in electrical connections, plus an insulating handle for user safety. The precision-machined spherical radius (SR) on the pin tip ensures it mimics real-world contact scenarios, delivering reliable results for checking if UK-standard electrical components block unauthorized access to dangerous parts.

Specifications:
• Test Pin Diameter:  Φ1mm (±0.02mm tolerance, ensures compatibility with BS 1363-1 gap requirements)
• Test Pin Length:  20mm (±0.05mm tolerance; critical for reaching potential hazardous parts)|
• Spherical Radius (SR):  Precision-machined SR on pin tip (matches BS 1363-1 Figure 1 dimensional specs)
• Material Composition – Pin: High-grade steel (corrosion-resistant, maintains diameter accuracy); – Handle: Insulating material (prevents electrical contact during testing)
• Key Tolerances:  Linear dimensions: ±0.05mm (aligns with BS 1363-1 Clause 9 precision requirements)

Test Procedures:
• Inspect the test pin for bent steel, cracked insulation, or worn tips; confirm diameter/length meet specs.
• Power off the plug/socket/adapter under test and place it on a stable, flat surface.
• Identify potential access points (e.g., gaps in plug prongs, socket openings) per BS 1363-1.
• Hold the insulating handle, align the pin tip with the target gap, and gently insert until resistance is felt.
• Check if the pin can contact hazardous live parts (via visual inspection or electrical testing).
• Record results to verify compliance with BS 1363-1 Figure 1.

Applications:
• Safety testing of UK-standard household plugs (e.g., 3-pin mains plugs) per BS 1363-1.
• Compliance checks for socket-outlets (e.g., wall sockets, extension lead sockets) intended for the UK market.
• Quality control for adapter manufacturers (e.g., travel adapters converting to BS 1363 plugs) during production.
• Third-party certification testing (e.g., UKCA, CE) for electrical components seeking UK market entry.
• Post-production audits of plug/socket batches to ensure consistent adherence to BS 1363-1 safety norms.
