BS 1363-1 Figure 32 Plug Pin Test Fixture

The BS 1363-1 Figure 32 Plug Pin Test Fixture is a precision-engineered measurement device specifically designed to evaluate the dimensional and structural conformity of plug pins according to the requirements specified in Figure 32 of BS 1363-1 (“13 A plugs, socket-outlets, adaptors and connection units – Rewirable and non-rewirable 13 A fused plugs. Specification”). This apparatus incorporates fixed and moving anvils manufactured to exacting dimensional tolerances, material specifications, hardness requirements, and surface finish parameters as mandated by the BS 1363 standard. With material hardness exceeding 50HRC and minimal thermal expansion characteristics, the fixture maintains exceptional dimensional stability and measurement repeatability, enabling precise verification of plug pin conformance to critical geometric specifications.

Specifications
• Compliance standard: BS 1363-1 (“13 A plugs, socket-outlets, adaptors and connection units – Rewirable and non-rewirable 13 A fused plugs. Specification”) Figure 32
• Core components: Fixed anvil and moving anvil
• Material hardness: Exceeds 50HRC
• Material thermal expansion coefficient: Minimal
• All linear dimensions: Specified in millimetres
• Key dimensional details: Includes R 4, R 6 radii, 45°, 40° angles, and critical length/width parameters as per standard
• Support requirement: Plug body must be supported to maintain face contact with the fixed anvil surface
• Alignment requirement: Moving anvil must be precisely aligned to the centre of the gap in the fixed anvil
• Key attributes (dimensions, tolerances, material, surface roughness): Fully compliant with BS 1363 standard requirements
• Dimensional stability: Maintains stability and reliability due to minimal thermal expansion coefficient

Test Procedures
• Prepare the plug sample for testing, ensuring the plug pins are free from damage, deformation, or debris that could affect test accuracy.
