Product No: SMT-B50H
Product Introduction
The 50mm Diameter Test Steel Ball is a specialized tool for mechanical impact resistance testing of electrical and electronic devices. It has a 50mm diameter and 500g weight, made of corrosion-resistant stainless steel to ensure consistent impact force. An integrated positioning ring helps align the ball accurately during tests, and it complies with IEC, UL, and CSA standards. It simulates accidental impacts to check if devices can withstand mechanical stress without safety risks, making it essential for verifying the durability of IT and audio/video equipment.

Specifications:
1. Diameter: 50mm, with ±0.1mm tolerance for precision impact simulation
2. Weight: 500g, ±5g tolerance to ensure consistent impact force
3. Material 304-grade stainless steel (corrosion-resistant, durable for repeated use)
4. Structural Feature Integrated positioning ring (for stable alignment during test setup)
5. Test Compatibility Suitable for free-fall impact tests on rigidly supported samples
Test Procedures:
1. Inspect the steel ball for cracks, dents, or rust; confirm weight and diameter meet specs.
2. Secure the test sample on a rigid supporting surface as required by the standard.
3. Use the positioning ring to place the steel ball at the specified start height.
4. Release the ball freely to let it impact the sample’s target area.
5. Check the sample for damage (e.g., cracks, loose components) after impact.
6. Record results to verify if the sample passes impact resistance requirements.
Applications:
1. Impact resistance testing of IT equipment (e.g., laptops, servers) per EN IEC 60950:2013 Figure 4A.
2. Safety verification of audio/video devices (e.g., TVs, speakers) following IEC 60065:2014 Figure 8.
3. Mechanical durability testing of electronic displays (e.g., monitors, tablets) during production.
4. Compliance checks for power adapters and chargers to meet UL 60950-1:2013 safety norms.
5. Impact testing of communication devices (e.g., routers, modems) for global market certification.
