ISO 7124 Sponge Foam Tester Repeated Compression Testing Use For Fatiguereciprocating Foam Polymeric
I. Purpose:
Sponge foam compression testing machine is mainly used for fatiguereciprocating foam polymeric material compression test, determination of residualdeformation rate. Then we can know the dynamic fatigue properties of materials.
II. Theory:
computer software control, first press 75% of the sample thickness, release and then press 25% for 20 seconds. Load cell force sensor will automatically record and show its force. That would be the hardness of the foam. Also 40%, 65% is programable.
III.Standards:
ISO7124-8.8 Permanent set after repeated compression
ISO 3385,
ASTM D3574,
GB/T10807-89,
ISO 2439-1980,
JISK6401
IV.Features:
- Ajust speed:adjust speed test according to different specimen.
- Indicating value verify: system enables display the accurate calibration of force
- Control method:select the test force,test speed,displacement,strain etc.test method.
- Curve ergodic:after the test,you can find out any curve point value and transformative data and analyse it.
- Display: dynamic display of the data and curve test process
- Result:The test result can be accessed.analyse the data curve.
- Limit: cell-type and machinery limit.
- Overload:automatic shutdown when exceed the rated value..
