2.3 APPLY PRESSURE AND RECORD RESULT
1. Increase pressure by turning handle clockwise, slowly and smoothly, until either of the following end
points:
•For destructive testing, the dolly and coating pulls off the substrate.
•For non-destructive testing, the minimum specified pressure value is reached.
If possible, complete the test within 90 seconds of starting. This is in accordance with some adhesion
testing standards.
2. Record the following information:
• Pressure - indicated by the gauge
• Test location
• Type of adhesive
• Substrate/adhesive temperature
• Air temperature
• Relative humidity
• Dewpoint temperature
• Coating system details
• Duration of tests
• Appearance of breaks, e.g. clean between coating and substrate, separation of coating layers,
jagged edges
