SB0704E 2 oz (57 g) Ground Pin Gauge Compliant with UL 498 Figure 119.3

SB0704E 2 oz (57 g) Ground Pin Gauge Compliant with UL 498 Figure 119.3 is engineered to the exact specifications of UL 498 Figure 119.3 (revised March 15, 2006) with a standardized 2 oz (57 g) configuration. All dimensional parameters, tolerance ranges, material characteristics, hardness values, and surface finish specifications fully conform to UL 498 regulatory requirements. The gauge maintains dimensional stability through utilization of low thermal expansion coefficient materials.

The gauge incorporates precise structural features including a 0.5 inch (12.7mm) diameter section, spherical full radius tip geometry measuring .1845 inch (4.69mm), and critical length dimensions of .797 inch (20.24mm) and .792 inch (20.12mm). A designated grinding orientation ensures measurement precision throughout the verification process. This instrument serves as an essential tool for validating structural and dimensional compliance of electrical plugs and sockets according to UL 498 standards.

Test Procedures

1. Prepare the plug or socket assembly for testing and verify the test environment meets standard requirements for gauge stability.
2. Identify the designated grinding orientation on the ground pin gauge and confirm the gauge exhibits no deformation or damage prior to testing.
3. Insert the ground pin gauge into the ground pin receptacle of the test specimen according to UL 498 Figure 119.3 structural alignment specifications.
4. Verify the dimensional fit between the gauge and test component falls within UL 498 specified tolerance ranges.
5. Check structural sha… (truncated)
