Explanation:
First, the main scope and function
     The machine according to GB / T6670-2008 design and manufacturing, in line with American Standard ASTM D3574 and ISO8307 test standard for the determination of flexible polyurethane foam falling ball rebound performance. The instrument by giving the ball a given diameter and quality at a predetermined height free fall on the foam sample, calculate the maximum height of the ball rebound and the ball drop height ratio of the percentage that the spring rate in rebound rate showing resilience foam. The machine has the use of safe, reliable measurement accuracy.
Second, the technical parameters Host
Ball drop distance: 460 ± 0.5% mm (GB) 500 ± 0.5% mm (American Standard)
Ball diameter: ¢ 16 ± 0.05 mm
Ball rebound Accuracy: <1.5%
Test specimen dimensions: 100 mm (length) × 100 mm (width) × 50mm (high)
Automatic calculation of the average Rebound
Area: 0.4m * 0.5m
