5.3  Failure Mode Recording

Many standards also require the user to record the mode of failure in varying degrees of complex-
ity. Proceq DY-2 allows the user to record the failure mode with the test result for comprehensive 
reporting. The possibility to record the failure is flexible enough to accommodate the requirements 
of the various standards.
e.g. ISO 4624 failure mode reporting classification.
•  A is a cohesive failure of the substrate;

•  A/B is an adhesive failure between the substrate and the first coat;

•  B is a cohesive failure of the first coat;

•  B/C is an adhesive failure between the first and second coats;

•  etc.

•  Estimate the area of fracture as a percentage to the nearest 10% for each type of fracture. 

The first column indicates where the break took place. The second column indicates the percentage 
of the break in that particular layer.
For simplified reporting as specified for example in ASTM C 1583, then the user would enter for 
example B 100% indicating a failure at the first coating.
•  Use the navigation keys to select the item from either column.

•  Define your own classifications for A, B, etc.

•  Use the center key to alter the value.

5.4  Emergency Stop

In case of an emergency the red-colored STOP button can be pressed. The instrument stops in any 
case and the following dialog appears:

•  Selecting the "Rewind" icon lets the instrument move back to its starting postition.

•  Selecting the "Cancel" icon lets you return to the main menu without any movement of the motor 

and you may proceed with the test.
