compression testing machine / foam
HAIDA EQUIPMENT CO., LTD
APPLICATIONS & TEST PURPOSE:
This machine is used to determine the recovery time of the slow recovery (viscoelastic) foams. ASTM D3574 is a commonly used standard for tests involving flexible cellular foam materials. Test M specifies a method for measuring the recovery time of slow recovery (viscoelastic) foams, like memory foam. It is an important test in the mattress industry.
DESIGN STANDARD : ASTM D 3574-2008
1.Prepare and condition the test specimen according to the geometries and guidance described in the test standard for IFD testing.
2.Place the specimen onto the perforated base compression platen. Lower the circular top platen onto the top of the specimen to apply a small preload and identify specimen thickness.
3.Indent the specimen to 75% of its original thickness at the speed referenced in the test standard.
4.After a specified dwell time, remove the circular top platen quickly to the specified deflection (close to original height), and record how much time it takes for foam to contact the top platen.
