BS1363-2 Figure 29 Calibration Jig for Calibrated Link

This BS1363-2 Figure 29 Calibration Jig for Calibrated Link is a precision calibration instrument engineered in strict compliance with BS 1363-2 Figure 29 specifications, designed exclusively for calibrating calibrated links utilized in testing 13 A electrical accessories. The jig incorporates a precision-assembled structure featuring self-aligning contacts, silver-plated beryllium copper fuse clips, and brass contact plates to ensure stable and accurate positioning during calibration procedures. The design incorporates intentional end float and clearance to facilitate self-alignment of contacts, while soldered joints between critical components guarantee reliable electrical connectivity. As an essential auxiliary instrument for compliance verification, this calibration jig ensures calibrated links meet the rigorous accuracy requirements specified in BS 1363-2 standards, supporting quality assurance and certification processes within the electrical accessory industry.

Specifications

• Test standard compliance: BS 1363-2 Figure 29 (dedicated for calibrated link calibration)
• Core components: Float, terminal stem (M3 × 25), insulating material, brass contact plate, fuse clip, contact assembly, and brass box/cover
• Material specifications: Box and cover manufactured from 1.25 mm brass sheet (clean natural finish); fuse clip fabricated from 0.45 mm thick beryllium copper (heat treated to minimum 170 HV, silver-plated, flat base)
• Structural design: Groove to accommodate contact plate; self-aligning contacts enabled by end float and insulation-box clearance
• Fastening details: Hole tapped M3 for terminal stem installation; cover functions as a push fit on the box (non-rigidly attached)
• Joint requirements: Soldered connections between clip, contact plate, and terminal stem ensure stable electrical performance
• Compatibility: Specifically designed for calibrating links employed in testing 13 A plugs, socket-outlets, adaptors, and connection units

Test Procedures

• Inspect the calibration jig for structural integrity, verifying that all components (fuse clip, contact plate, terminal stem) are … (truncated)
