• Surface roughness: Meets UL 498 specified standards

Test Procedures:

1. Inspect the test probe for cleanliness, no visible damage, or dimensional irregularities prior to use.
2. Secure the plug or socket under test in a stable fixture to prevent movement during inspection.
3. Align the probe with the designated testing position of the product as outlined in UL 498 Figure 132.2.
4. Conduct structural and dimensional inspection by guiding the probe through the relevant features of the test sample.
5. Verify if the product’s structure and size align with the tolerances and specifications of UL 498.
6. 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.
