UL 62368-1/UL 1989 Steel Ball with 12.7mm/0.5 inch Diameter

This UL 62368-1/UL 1989 Steel Ball with 12.7mm/0.5 inch Diameter is a specialized safety testing tool designed for small, compact electronic devices—such as wireless earbuds, phone chargers, smartwatches, and portable sensors. It delivers controlled, low-force impacts to test the structural integrity of tiny enclosures, verifying if they can withstand real-world small-object collisions (e.g., accidental drops onto hard surfaces) without cracking, deforming, or exposing internal hazardous parts (like lithium-ion batteries or live circuits). Crafted from solid carbon steel for consistent weight and precision, it’s UL-compliant, durable for repeated use, and critical for manufacturers to ensure small devices meet U.S. safety standards.

Specifications:
Tool Type: 12.7mm (0.5-inch) UL Steel Ball (for small electronic device impact testing)
Material: Solid carbon steel (high density: 7.85g/cm³; resistant to deformation; ensures consistent impact force)
Diameter: 12.7mm (0.5-inch) ± 0.05mm (precision-machined for UL compliance)
Surface Treatment: Smooth, deburred finish (prevents scratches on delicate device enclosures; ensures even impact distribution)
Typical Impact Height: 0.5–1.0 meters (adjustable per standard; lower heights suit fragile small devices)
Core Function: Tests small electronic device enclosures for resistance to small-object impacts; verifies no hazard exposure post-impact

Test Procedures:
1. Inspect the steel ball for damage (dents, cracks, or rough edges) to ensure test accuracy.
2. Secure the small device (e.g., wireless earbud case) on a flat, non-slip surface—align the target enclosure area.
3. Adjust the test setup to the specified impact height (e.g., 0.7 meters for chargers) and position the ball above the device.
4. Release the ball freely (no extra force) to let it impact the device’s enclosure.
5. After impact, check for enclosure cracks, deformation, or exposed internal parts (e.g., batteries, wires).
6. Record results: pass if the enclosure remains intact; fail if damage or hazards are exposed.

Applications:
1. Impact testing of wireless earbud and headphone cases (per UL 62368-1:2023 Figure 7.4.2) to protect internal batteries.
2. Safety checks for compact phone chargers and power banks (Class 2 power units) compliant with UL 1310:2023.
3. Structural verification of smartwatch and fitness tracker casings to resist small-object impacts (UL 1989:2023).
4. Quality control for portable sensor enclosures (e.g., temperature sensors) during manufacturing.
5. Post-production testing of small medical auxiliary devices (e.g., glucose meter casings) to meet U.S. UL standards.
