UL 498 Figure 124.3 Pushout Tool

This UL 498 Figure 124.3 Pushout Tool is engineered to the exact dimensional specifications defined in UL 498 Figure 124.3, the authoritative standard for attachment plugs and receptacles. It functions as a specialized testing instrument for evaluating component retention strength and securement in plugs and receptacles, ensuring electrical products meet UL 498 safety and performance requirements for quality control and compliance verification in manufacturing and testing laboratories.

Specifications

• Full compliance with UL 498 standard requirements, specifically aligned with Figure 124.3 specifications for attachment plugs and receptacles
• Precision dimensional tolerances with critical measurements in inches: 1.500±.010, ±.020, 3.000, and 375 MIN
• Calibrated precision features with dimensions: 1.532, 1.530, .242, .240, .499, .501, .055, and .056
• Engineered for accurate pushout force testing to assess component retention in plugs and receptacles
• Manufactured to ensure consistent performance and repeatable test results

Test Procedures

1. Verify the pushout tool is properly calibrated and inspect for dimensional accuracy before testing.
2. Prepare the test sample (attachment plug or receptacle) and confirm it is free from damage, deformation, or contamination that may affect test results.
3. Secure the sample in a stable fixture, positioning it to align with the tool’s contact points as specified in UL 498 Figure 124.3.
4. Align the pushout tool with the target component (e.g., pin, terminal) in the sample, ensuring proper contact without damaging the sample.
5. Apply a controlled, steady force using the tool to push the component, following the test parameters outlined in UL 498.
6. Monitor and record the force required to displace the component or verify that the component remains securely retained within the specified limits.
7. Check if the sample’s…
