Provides a procedure for determining the adhesion of paint coatings using pressure-sensitive adhesive tape.

This Standard sets out a method for assessing the adhesion of paint coatings to substrates by applying and removing pressure-sensitive adhesive tape over cuts made in the coating. The method is also applicable as a field procedure, when not under the controlled environmental conditions of AS 1580.101.1, however the temperature of the surface needs to be recorded. It is not applicable to soft or friable substrates where the coating thickness is less than 50 mm.NOTES:1 The method is not considered suitable for coatings thicker than 125 mm.2 The method does not distinguish between high levels of adhesion for which more complex procedures are required, such as a pull-off adhesion test similar to ASTM D4541 or ISO 4624.3 In multicoat systems, if adhesion failure occurs between coats, the adhesion of the coating system to the substrate cannot be determined.
