Automatic Ball Rebound Foam Furniture Testing Machines ISO 8307 / ASTM D3574

Application

Foams Ball Rebound Tester  is suitable for soft foam polymeric material falling ball rebound rate measurement.

Theory
1. A certain mass and the diameter of the ball, falling from the fixed height down to the sample surface, then measure the height of the ball bounce, calculate ball bounce height and the percentage of the drop height ratio.
2. This machine adopts the microprocessor control, LCD display, and can print the test data.

3. The machine has the characteristic for safety use, reliable, higher measurement precision. 

The Usage

Foams Ball Rebound Tester is designed and manufactured in accordance with ASTM GB/T6670-2008, American Standard D3574and ISO8307 testing standards. And it suits for testing rebound performance of soft polyurethane foam ball. The tester through a given diameter and weight of iron ball dropping on foam sample at a certain height, and then calculate the percentage between maximum height of iron ball rebound and the height of iron ball dropping, this percentage is also called resilience ratio . Resilience ratio means foam rebound performance of poly foam. The tester adopts the microprocessor control, Chinese liquid crystal display, and it can print the test result. The tester is safe, reliable, with high measuring precision.
