WebbThe angle of the sloping plate should always be added to the result. The standard angle of the sloping plate may change from 20° to 40° depending on the characteristics of the test piece or 30° as mentioned above. In addition, the ball start position must be constant in length of 100mm for the entire ball to roll, even if the ball size changes. WebbProbe tack The probe tack test is a powerful tool to gain information about the debonding mechanism of an adhesive. The parameters influencing the results of the probe tack test are the rheological properties of the adhesive layer and the nature of its interaction with the surfaces of the substrate and the probe.[4] how often to birds lay eggs
