SPC-01 ASTM D5458 1 Stretch film peel tack and lap tack detection

Principle:

Peel cling testing requires two different types of samples. The first sample is larger piece as backing placed on test bed. The second piece is a smaller strip which is peeled off the larger sample.  

The larger sample is wrapped fixed on the incline surface and the smaller sample is attached to a clip, connected with loadcell. It's pulled after it's clung to the large sample and the force is measured during the pulling. 

We recommend the way described in ASTM D5458, which, during the test, reduces the influence of frictions in a tensile tester and pulley. 

It complies with ASTM D 5458, BB/T 0024.

Technical features

1.  7 inch TFT touch screen operation (human machine interface)

2.  PLC control unit inside for stable performance

3.  Precision ball screw for accurate speed & displacement.

4. Test speed is adjustable.

5. Different connection of loadcell with sample eliminates the interference caused by the friction and gravity of             pulley and string, which are commonly used in traditional method.

6.  Limiting device and automatic returning.

7.  Real time display of test curve, peak value recording.

8.  Supportive line of elongation rates, 50%, 100% and 200%.

9.  Microprinter

10.Coefficient of friction function can be added (Optional)
