EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of JIS K6400-3 testing. This standard specifies a method for determining the flexibility of flexible cellular polymeric materials by ball rebound.
A steel ball is dropped from a certain height on the test piece and the rebound height is measured. The recoil tester shall consist of a vertical transparent tube with an inner diameter of 30 mm to 65 mm. A steel ball with a diameter of 16 mm ± 0,5 mm and a mass of 16,8 g ± 1,5 g is dropped vertically on the test instrument part by means of a tube from a height of 500 mm ± 0,5 mm with a magnet or other tool. suitable device. The steel ball must be released to drop from rotation and be centered effectively.
This standard specifies a method for determining the flexibility of flexible cellular polymeric materials by ball rebound. A steel ball is dropped from a certain height on the test piece and the rebound height is measured.
If the tube is not held in a vertical position, measurement errors may occur and measurements may be invalid due to the contact of the recoil ball with the inner surface of the tube. It is therefore recommended that the pipe be mounted at right angles to the rigid baseplate and that the baseplate itself is horizontal.
