ASTM D3574 Computer Servo Control Foam Indentation Force Deflection Tester Resolution 1/1000

ASTM D3574 Computer Servo Control Foam Indentation Force Deflection Tester 1/1000

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 programmable.

Standards:

GB/T10807-89,ISO 2439-1980, JISK6401, ASTM D3574 Test B-IFD Test

ITI. Features:

• Adjust 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..
