Assessing The Results - Failure Attributes
Many National and International Standards, including ISO 4624 & ASTM D4541, require the user to record not only the pull-off force but also the nature of the failure. This is done by examining the bottom of the dolly and assessing the failure. In ‘Advanced’ mode on the Elcometer 510 it is possible to select the 'Attributes' feature (Menu/Setup/ Gauge Mode/Advanced) allowing the nature of the fracture to be recorded against each reading and stored within the batch.
Examining The Dolly
a) Cohesive Failure: The coating fails within the body of a coating layer leaving the same coating on the surface and on the dolly face.
b) Adhesive Failure: Failure occurs at the interface between layers (intercoat) where one pulls away from the other. The “coating” on the dolly face will not be the same as that on the test area.
c) Glue Failure: When no coating is present on the dolly it must be recorded as a failure of the glue. This may be due to incorrect or insufficient mixing of the component parts of the adhesive, incompatibility between the adhesive/coating/dolly/test surface.

Pull-Off Adhesion Tests - Preventing Adhesive and Cohesive Failures
Preparing the surface and dolly
- Select an appropriate test area which is flat and has sufficient area to attach the adhesion gauge.
- Abrade the dolly and surface, clean both to remove any dust - minimizing the rish of an 'adhesive' failure.
Fixing the dolly
- Mix the adhesive correctly and apply a uniform adhesive film over the entire dolly face.
- Test Standards require that the dolly is pulled off perpendicularly to test surface. The dolly must therefore be adhered on to a prepared flat test surface (see images below). Apply an even pressure to the dolly to ensure that the dolly face is parallel to the test surface.
- Remove any excess adhesive from around the dolly and allow to fully cure. Tape may be required when applying dolies to vertical surfaces during the cure process.
- If required, once the dolly has fully cured, score the coating around the dolly using the dolly cutter provided.
- Attach the gauge actuator to the dolly and begin test.
Assessment of the Adhesion Test
For a valid pull test the coating must cover at least 50% of the area of the dolly face. If the glue fails and no coating is
present on the dolly, or it covers less than 50% of the dolly face area, the pull-test is invalid and should be repeated.
When the coating has failed within the layer leaving the same coating on both the dolly and the test panel it is known
as a ‘cohesive failure’.
‘Adhesive failures’ occur when either the coating has failed at the interface with another coating (leaving a coating on the dolly and another coating on the substrate), or when the coating has failed at the substrate (leaving the
coating on the dolly and the substrate is bare).
NOTE: If the glue fails at a value above the specification then it can be reported that the adhesion exceeded the
specification for this individual test.
