I. purpose:

The unit according to gb/t6670-97 or iso8307 or astmd3574 design and manufacturing. Is suitable for the determination of soft polyurethane foam falling ball type can rebound resilience. This instrument through a given diameter and the quality of steel ball in the specified height on free falling on the foam sample, calculate the springback of large height of steel ball and ball drop height ratio is the percentage of spring rate, expressed as a resilient rate of foam plastics can rebound resilience.

Ii. Main technical indicators:

1. Rebound accuracy: the relative accuracy is less than 1.5%

2. Falling height of steel ball (mm) : 460+0.5%(gb/t6670-97)

500+0.5% (astm d3574 and iso8307)

3. Diameter of plastic pipe: 40±4mm

4. Diameter of steel ball: phi =16-0.15

5. Steel ball mass: 16.7-0.5g

6. Measuring range: 10%-100%

7. How to read: digital display

8. Sample size: 100×100×50mm

9. Test tray is adjustable

3. Complete machine system:

1. One main engine

2. One set of control system

3. Two steel balls

4, set a ring

5. Four feet

6. One micro printer
