Ball Rebound Foam Furniture Testing Machines ASTM D3574 With LCD Touch Screen
Pecifications:
ASTM D3574 LCD Touch Screen Ball Rebound Foam Furniture Testing Equipment
1. LCD Touch screen interface
2. According to ASTM D3574 and ISO 8307
3. Automatic calculate result
The Usage:
ASTM D3574 LCD Touch ScreenBall Rebound Foam Furniture Testing Equipment 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.
Parameter:
| 1. Distance of iron ball dropping | 460+0.5%mm ( GB), 500+0.5%mm ( American Standard ) |
| 2. Diameter of iron ball | 16 ± 0.05 mm |
| 3. Controller | Use microprocessor to control, LCD Chinese display, and print test data. |
| 4. Ball rebound accuracy | <0.5% |
| 5. Test sample size | 100 mm (L) × 100 mm (W) × 50 mm (H) |
6. Automatic calculation of average rebound height
7. Configuration of Automatic calculation of average resilience ratio
8. One set of tester (including release mechanism, capture mechanism and height adjustment mechanism)
9. One set of electro-optical distance measurement sensor
10. One set of control box(Chinese LCD display)
11. One set of micro type printer(desktop)
