IEC 60311 38.1mm Impact Test Steel Ball without Ring

The IEC 60311 38.1mm Impact Test Steel Ball (Without Ring) is a specialized safety testing tool designed for rubber and plastics insulated cables, wires, and electrical insulation materials. Its large 38.1mm diameter (solid carbon steel construction) delivers targeted, controlled impact force to simulate real-world external stress—such as accidental drops or pressure on cable insulation/sheaths. Without a suspension ring, it’s optimized for direct, stable placement in dedicated impact test setups, verifying if materials resist cracking, tearing, or insulation failure. Strictly compliant with IEC 60311, it’s essential for manufacturers to validate cable/insulation durability and meet global electrical safety regulations.

Specifications:
Tool Type: IEC 60311 Impact Test Steel Ball (38.1mm diameter, no ring; for cables/insulation testing)
Material: Solid carbon steel (density: 7.85g/cm³; high rigidity, no deformation under standard impact; corrosion-resistant)
Key Dimensions:
– Ball diameter: 38.1 mm
– Ball weight: 227 g
Surface Treatment: Smooth, deburred finish (prevents artificial damage to test samples; ensures even impact distribution)
Typical Impact Height: 0.5–1.0 meters (adjustable per material type; specified in IEC 60311 for cables/insulation)
Core Function: Delivers controlled impact to test cable insulation/sheaths and electrical insulation materials; verifies resistance to cracking/tearing

Test Procedures:
1. Inspect the steel ball for damage (dents, cracks, rough surfaces) to ensure test accuracy.
2. Secure the cable/insulation sample on a rigid, flat base—align it with the ball’s drop path.
3. Adjust the test setup to the specified impact height (e.g., 0.8m for cable insulation).
4. Place the steel ball at the target height and release it freely (no external force) to impact the sample.
5. After impact, visually inspect the sample for cracks, tears, or insulation layer failure.
6. Record results: pass if no damage; fail if material integrity is compromised.
