BS 1363-1 Figure 28 Calibrated Link Test Component

This BS 1363-1 Figure 28 Calibrated Link Test Component is a precision-engineered measurement device specifically designed to meet the exacting requirements of BS 1363-1 Figure 28 for performance evaluation of 13 A rewirable and non-rewirable fused plugs, socket-outlets, adaptors, and connection units. The component features an assembled construction comprising a resistive element, standard ceramic tube, end caps, and filling material, with hard-bright silver plating and a taper ream design to facilitate soldering operations. The calibrated link enables precise watt-loss adjustment through a dedicated filing length, ensuring consistent and repeatable test conditions that comply with international electrical safety and performance standards, making it an essential instrument for compliance verification and quality assurance in electrical accessory manufacturing and testing laboratories.

Test Procedures

• Confirm the test objectives and ensure the calibrated link is compatible with the 13 A electrical accessory (plug, socket-outlet, adaptor, or connection unit) to be tested.
• Inspect the calibrated link for structural integrity and verify that all components meet the specifications outlined in BS 1363-1 Figure 28.
• Prepare the test setup according to standard requirements, ensuring proper connection and alignment of the calibrated link with the device under test.
• Perform watt-loss adjustment using the dedicated filing length to achieve the specified test conditions as per BS 1363-1.
• Execute the performance testing sequence, monitoring parameters to ensure compliance with standard-defined thresholds.
• Document all test results and verify that the electrical accessory meets the performance criteria specified in BS 1363-1.
• Maintain calibration records and perform periodic verification to ensure ongoing measurement accuracy and traceability.
