ISO 7124 Foam Testing Equipment For Permanent Set After Repeated Compression Testing

ISO 7124 Foam Test Apparatus For Permanent set after Repeated Compression Testing

I. Purpose:

Use to test the indentation hardness for elastic foaming material, such as compounded foam, PU foam.

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, ASTM D3574 Test B-IFD Test

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..
