Elcometer 108 Hydraulic Adhesion Tester
Test Method

The dolly is glued to the surface under test, making sure that the internal hole in the dolly is clear from adhesive.

The instrument is then attached to the dolly glued to the coating surface.

Turning the instruments handle increases the hydraulic pressure which forces the dolly away from the substrate.

The value of the force is displayed and recorded on the dial.

Pipemaster heating tongs are supplied with the kit remove dollies from test pieces thus making the adhesion fully non-destructive. Used in accordance with ASTM D451 and ISO 4624 test methods.

Note: For ISO 4624 an additional dolly cutter is required (T10814009) as this test requires a coating to be cut around the dolly prior to testing
