Measurement of difference in height from perimeter trims to panel surface

The stripes shall have the following dimensions:

strip width b shall be 50 mm, strip length x shall be at least half the panel size.

The arrows in the figure show the direction of pull. A peel angle of 90° to the panel level shall be applied. During the test the pulling power F in the hatched area of the strips is constantly monitored and recorded. The mean peel resistance of the test strip is derived from the following equation:

mean peel resistance =(mean.pull.power)/(width.of .test.strip) N/MM
