BS 1363-2 Figure 1 Test Pin

The BS 1363-2 Figure 1 Test Pin is a precision dimensional verification instrument engineered to validate that 13A socket-outlets (both switched and unswitched configurations) prevent inadvertent contact with live electrical components—a critical safety requirement during plug insertion and withdrawal operations. This tool incorporates a corrosion-resistant steel probe with a precisely machined spherical tip for accurate gap navigation and an insulated handle constructed from high-resistance plastic (≥100MΩ) with thermal stability up to 110°C, ensuring operator protection during testing procedures.

Manufactured to exacting dimensional tolerances specified in BS 1363-2, this test pin verifies that live components remain inaccessible when socket-outlets are mounted and wired according to standard installation practices. Deployed in manufacturing quality control, laboratory verification, and compliance testing environments, it ensures 13A socket-outlets meet UK and international electrical safety standards, thereby mitigating electric shock hazards.

Technical Specifications:

• Tool Classification: Test Pin (BS 1363-2 Figure 1; for live part accessibility verification in 13A socket-outlets)
• Probe Construction: Steel alloy (corrosion-resistant; spherical tip radius (SR) for smooth insertion; rigid structure maintains dimensional accuracy)
• Handle Construction: Insulating polymer (electrical resistance ≥100MΩ; thermal rating: 110°C maximum; ergonomic design for precise manipulation)
• Critical Dimensions (mm):
  • Length Segments: 20.00-19.95mm, 29.8–30.2mm, 49–51mm
  • Total Probe Length: Compliant with BS 1363-2 gauging specifications
  • Dimensional Tolerances: ±0.05mm for linear dimensions ≤25mm; ±0.2mm for dimensions exceeding 25mm
• Primary Function: Verifies 13A socket-outlets prevent access to live parts; validates dimensional compliance with BS 1363-2; ensures user safety during normal plug operation
• Compatibility: Engineered for 13A switched/unswitched socket-outlets (residential, commercial, and industrial variants)
• Standard Test Protocol:
  1. Inspect test pin for mechanical integrity: verify tip sphericity, check for dimensional deformation, examine insulation for cracks
  2. Mount and wire the equipment-under-test (EUT) socket-outlet according to standard installation practices
  3. Grasp insulated handle, insert steel probe into all EUT apertures (socket slots, clearance gaps)
  4. Manipulate probe systematically to assess potential contact with internal live components
  5. Monitor for probe contact with live parts (supplement with live-part detection equipment if required)
  6. Document test results: Pass condition requires zero contact with live components; … (truncated)
