UL 498 Figure 132.2 Large Test Probe

This UL 498 Figure 132.2 Large Test Probe is engineered with precision to validate the structural and dimensional compliance of plugs and sockets with UL 498:2009 standards, specifically meeting the requirements of Figure 132.2. It adheres strictly to standard specifications for dimensions, tolerances, material quality, and surface properties, featuring high material hardness and minimal thermal expansion for consistent, reliable performance in electrical component inspection.

Specifications:
• Applicable standard: UL 498 Figure 132.2
• Key diameter (1): 0.030 in ± 0.002
• Radius (R): 0.125 in ± 0.005
• Key diameter (2): 0.060 in ± 0.001
• Angle: 45°
• Length segment (1): 0.150 in ± 0.005
• Overall length: 1.00 in ± 0.030
• Material hardness: ≥50HRC
• Material thermal expansion coefficient: Small, ensuring dimensional stability
• Dimensional tolerances: Compliant with UL 498 requirements
• Surface roughness: Meets UL 498 specified standards

Test Procedures:
• Inspect the test probe for cleanliness, no visible damage, or dimensional irregularities prior to use.
• Secure the plug or socket under test in a stable fixture to prevent movement during inspection.
• Align the probe with the designated testing position of the product as outlined in UL 498 Figure 132.2.
• Conduct structural and dimensional inspection by guiding the probe through the relevant features of the test sample.
• Verify if the product’s structure and size align with the tolerances and specifications of UL 498.
• 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 standards.
• Quality control in the manufacturing process of electronics and electrical appliances.
• 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.
