ISO 8307 Sponge & Foam Ball Rebound Tester
This precision testing machine measures the elasticity and rebound rate of soft polyurethane foams according to international standards ASTM D3574, ISO 8307, and GB/T6670-97.
The instrument calculates rebound height percentage by dropping a calibrated steel ball from specified heights onto foam samples, providing accurate resilience measurements for quality control and material testing applications.
