Sponge foam rebound tester DMS-MJ

Sponge foam rebound tester
Application: It is applicable to the determination of falling ball resilience of soft foam polymer materials.
Principle:
A steel ball with a certain quality and diameter is dropped from a fixed height onto the surface of the specimen, and the height of the steel ball's bounce is measured to calculate the percentage of the ratio of the bounce height to the drop height.
1. The machine is controlled by a microprocessor, with a Chinese LCD display and the ability to print test data.
2. This machine has the characteristics of safe use, reliability, and high measurement accuracy.
According to the standard:
Standards: ASTM D3574 and ISO8307:2007 (Soft foam polymer material - Determination of rebound performance by falling ball method), GB/T6670-2008 (Determination of rebound performance by falling ball method of soft foam polymer material).
Technical specifications:
1. Drop distance of steel ball: 460 ± 0.5% mm (national standard) 500 ± 0.5% mm (American standard)
2. Steel ball diameter: ￠ 16 ± 0.05 mm
3. Precision of ball rebound rate: 4. Testing host size: 35cm (length) x 35cm (width) x 60cm (height)
