CSI-212I (Impact Tester )
The CSI Impact Tester is used to measure the ability of a fiber optic cable to withstand repeated impact under controlled test conditions as prescribed by the referenced test methods.

The Drop Hammer assembly is designed to provide a free vertical fall onto the fiber optic cable. The striking surface is cylindrically shaped with a minimum length of 50 mm and unless otherwise specified a shaped with a minimum length of 50 mm and unless otherwise specified a radius of curvature of 10 mm. The striking surface and anvil are hardened to RB-90. The drop hammer assembly is adjusted so the axis of the striking surface will be at right angles to the axis of the cable.
The cyclic arm is driven by an electric motor whose speed is adjustable so that the cyclic arm is driven at 30 cycles per minute.
The masses are made of steel and plated for corrosion protection.

The Impact Tester includes:

Steel base
Upright frame supporting the drive mechanism
Impact hammer
Sample holding clamps

The apparatus consists of:

Clamps
Masses
Drive assembly
Adjustment screw to induce impact loads as stipulated in the below named test specifications
