Description

The SB1276A Receptacle Test Fixture is a precision measurement instrument engineered to validate the structural dimensions of electrical plugs and receptacles in accordance with UL 498 Figure 118.1 specifications. This fixture ensures compliance with international safety standards including UL 498, IEC 60884, and GB 2099 through rigorous dimensional verification. Its construction features material hardness exceeding 50HRC and minimal thermal expansion coefficient, providing exceptional dimensional stability and measurement repeatability across varying environmental conditions.

Technical Specifications
• Material hardness: >50HRC (Rockwell C scale)
• Dimensional tolerances: Fully compliant with UL 498 Figure 118.1 requirements
• Thermal expansion coefficient: Minimal for dimensional stability
• Surface finish: Meets specified roughness criteria per standard
• Critical dimensions: 3.286/3.276 in., 2.937/2.932 in. (dual positions, ±0.005 in. tolerance), 1.750 in. radius (125R), 0.500 in. (±0.020 in. tolerance), and 3.938 in. (hard dowel configuration)

Test Methodology
• Prepare the receptacle under test and ensure the fixture surfaces are free of contaminants that could compromise measurement integrity.
• Align the test fixture with the receptacle structure, ensuring proper engagement of the hard dowel and dimensional gauging elements with corresponding features on the test specimen.
• Verify receptacle fit within the fixture according to specified dimensional parameters, assessing structural compatibility between the component and gauging sections.
• Confirm all critical dimensions comply with UL 498 tolerance requirements through visual inspection of fit characteristics and supplementary measurement verification as required.
• Document test outcomes, recording compliance status based on fixture engagement and dimensional verification results.

Application Scenarios
• Quality assurance testing of plugs and receptacles in electrical manufacturing to verify compliance with UL 498, IEC 60884, and GB 2099 safety standards
• Performance validation of electrical appliance connection interfaces, ensuring compatibility and safety of integrated receptacles
• Production line quality control for plug and receptacle manufacturers, enabling batch compliance verification
• Third-party certification testing of electrical connection devices by accredited testing laboratories, providing objective compliance assessment for product certification
