SB1622E 4 oz (113 g) Ground Pin According to UL 498 Figure 119.4

SB1622E 4 oz (113 g) Ground Pin According to UL 498 Figure 119.4 is a high-precision and standard-compliant testing component specifically developed to meet the requirements of UL 498 Figure 119.4. It is mainly used to verify the dimensional accuracy, insertion compatibility, and grounding reliability of ground terminals in electrical receptacles. Manufactured with high-quality wear-resistant alloy materials and undergoing strict dimensional calibration and performance testing, it features excellent structural stability and long-term wear resistance. The product can provide accurate and repeatable testing results for manufacturers, certification institutions, and quality control departments, effectively ensuring that tested receptacles meet the safety and performance standards specified in UL 498, and is an essential testing tool in the quality assurance process of electrical connection components.

Specifications
• Weight: 4 oz (113 g), fully consistent with the weight requirement specified in UL 498 Figure 119.4
• Material: High-hardness alloy, with a hardness rating of ≥ 58 HRC to ensure wear resistance and service life
• Dimensional parameters and tolerances: Strictly comply with the relevant provisions of UL 498 Figure 119.4, including pin diameter, length, tip geometry, and grounding contact surface size
• Surface treatment: Adopts anti-corrosion and anti-oxidation coating technology to maintain dimensional stability and surface integrity in harsh testing environments
• Grounding contact performance: The contact surface is precision-machined to ensure good contact with the receptacle’s ground terminal during testing
• Operating temperature range: -20℃ to 65℃, adaptable to laboratory, workshop, and other common testing environment conditions
• Compatibility: Suitable for both manual testing operations and automated testing systems, with strong scenario adaptability

Test Procedures
• Pre-test preparation: Clean the ground pin and the receptacle to be tested to remove surface dust, oil stains, or debris that may affect the testing effect; check whether the ground pin is intact without deformation or damage, and confirm that the testing environment meets the standard requirements (temperature, humidity, etc.).
• Fix the test sample: Secure the receptacle to be tested on a stable testing platform or fixture to prevent displacement during the insertion process, ensuring the accuracy of the testing position.
• Align the test pin: According to the technical requirements of UL 498 Figure 119.4, align the ground pin with the ground terminal slot of the receptacle at a specified angle, ensuring that the insertion direction is vertical and free of tilting.
• Perform insertion test: Insert the ground pin into the receptacle’s ground terminal at a uniform and controlled speed; if necessary, use professional force-measuring equipment to record the insertion force and retention force to verify whether they are within the standard-specified range.
• Verify grounding performance: After the ground pin is fully inserted, check whether the contact between the pin and the receptacle’s ground terminal is reliable, and confirm that there is no loose contact or poor grounding phenomenon.
• Complete the test process: Slowly withdraw the ground pin from the receptacle, inspect the pin and the receptacle’s ground terminal for deformation, scratches, or other damages; record all test data in detail, including insertion smoothness, force values (if tested), and contact status.
• Judge compliance: Based on the test results and the requirements of UL 498 Figure 119.4, judge whether the tested receptacle meets the standard compliance requirements.

Applications
• Batch quality inspection of household and commercial electrical receptacles in manufacturing enterprises, ensuring that the grounding performance and dimensional accuracy of products meet UL 498 standards.
• Compliance verification of ground terminal components of industrial power sockets by third-party certification institutions, providing reliable testing basis for product UL certification.
• R&D and prototype testing of new receptacle products, helping R&D teams optimize the design of ground terminals to ensure that product performance meets standard requirements.
• Incoming quality control of receptacle components by electrical appliance assembly enterprises, preventing non-compliant ground terminal components from entering the production line.
• Periodic safety inspection and maintenance of in-service receptacles in commercial buildings, residential areas, and industrial workshops, assessing whether their grounding function is still effective and compliant.
• Teaching and training in electrical engineering and safety testing related majors, demonstrating the testing process and standard requirements of receptacle grounding performance.
