UL 498 Figure 105.1 Test Gauge

This UL 498 Figure 105.1 Test Gauge is precision-crafted to verify the structural and dimensional compliance of plugs and sockets with UL 498:2009 standards, specifically aligning with the revised requirements of Figure 105.1. It adheres strictly to standard specifications for dimensions, tolerances, material properties, and surface finish, featuring high hardness, minimal thermal expansion, and stable performance to ensure accurate and reliable electrical component inspection.

Specifications:
• Applicable standard: UL 498 Figure 105.1
• Key diameters: 0.156 in, 0.125 in, 1.375 ± 0.010 in, 0.0672 in, 0.051 in, 0.050 in, 0.033 in, 0.030 in
• Flat blade thickness: 0.126 in / 0.124 in
• Critical length dimensions: 0.469 in, 0.467 in, 0.251 in, 0.249 in, 0.360 in, 0.358 in, 0.719 in, 0.717 in
• Angle: 45° (both sides)
• Grounding pin: Removable with snug fit, installed in a hole with ±0.0002 in tolerance
• Material hardness: ≥50HRC
• Material thermal expansion coefficient: Small, ensuring dimensional stability
• Dimensional tolerances: Compliant with UL 498:2009 requirements
• Surface roughness: Meets UL 498 specified standards

Test Procedures:
• Inspect the test gauge for cleanliness, no visible damage, or dimensional irregularities before use; ensure the removable grounding pin is snugly fitted.
• Secure the plug or socket under test in a stable fixture to prevent movement during inspection.
• Align the gauge with the designated testing position of the product as outlined in UL 498:2009 Figure 105.1.
• Conduct structural and dimensional inspection by guiding the gauge through the relevant features (slots, holes) of the test sample.
• Verify if the product’s structure and key dimensions align with the tolerances and specifications of UL 498:2009.
• Document the test data and confirm whether the product meets the standard’s compliance criteria.

Applications:
• Structural and dimensional inspection of plugs and sockets to ensure conformity with UL 498:2009 standards.
• Quality control processes in the electronics and electrical appliance manufacturing industries.
• Conformity testing for plug and socket products on production lines and in workshops.
• R&D testing for optimizing the design of plug and socket components.
• Compliance verification in third-party testing laboratories and certification institutions.
