Foam Compression Recover Time Tester HD-F750-5 OEM Wholesale
For reference only
APPLICATIONS & TEST PURPOSE:
This machine is used to determine the recovery time of the slow recovery (viscoelastic) foams.
DESIGN STANDARD : ASTM D 3574-2008
place the test specimen on the perforated supporting plate,bring the indentor foot into contact with the specimen with a 4.5N preload to detemine the specimen's initial thickness at speed of 1000± 100 mm/min, after a 60-s dwell time,return the indentor to a 5% deflection at 1000± 100 mm/min,starting a stopwatch immediately at 1000± 100 mm/min,starting a stopwatch immdiately upon initiating the upward movement of the indentor, stop the watch as soon as the foam recovers to a 4.5N preload on the indentor, if there is no separation between the foam and the indentor, if there is no separtion between the foam and the indentor foot during the upward movenment of the indentor foot,the recovery time is indeterminate by this method.
