Falling ball rebound instrument

製品紹介：

The falling ball rebound instrument is designed and manufactured according to GB/T6670-2008 or ISO8307 or ASMD3574. It is suitable for determining the falling ball rebound property of soft polyurethane foam. The instrument calculates the maximum rebound height of the steel ball and the percentage of the falling height of the steel ball by the steel ball with a given diameter and quality falling freely on the foam sample at a specified height, and the rebound rate represents the resilience of the foam.

Performance parameters:

- Drop ball rebound accuracy: relative accuracy is less than 1.5%

- Steel ball falling height （mm） : 460±0.5%（GB/T6670-97）

-500 ±0.5%（ASTMD3574 and ISO8307）

- Plastic pipe diameter: 40±4mm

- Ball diameter: Φ=16±0.5

- Steel ball mass: 16.7±1.5g

- Measuring range: 10%——100%

- Reading mode: color crystal display

- Sample size: 100×100×50mm
