ISO 4624. PAINTS AND VARNISHES – PULL-OFF TEST FOR ADHESION
ISO 16276-1. CORROSION PROTECTION OF STEEL STRUCTURES BY PROTECTIVE PAINT SYSTEMS – ASSESSMENT OF, AND ACCEPTANCE CRITERIA FOR , THE ADHESION/COHESION (FRACTURE STRENGTH) OF A COATING – PART 1: PULL-OFF TESTING
The Adhesion Tester or Pull Off Tester is one of the most accurate and versatile adhesion testers currently available. It measures the adhesion bond strength of applied coatings with ease and precision.
The adhesion is measured by the tensile pull on a Dolly glued to the coating surface.
The force is applied through the centre of the Dolly by a hydraulically loaded pin.
This ensures an exactly central point loading of the force.
Adhesion values are recorded by a pressure gauge giving a 1:1 pressure reading.
This is made possible as the net surface area of the Dolly is equal to the surface area of the hydraulic piston bore. Pressure reacted by the Dolly is the same as the pressure in the bore and is transmitted directly to the pressure gauge.
The maximum value achieved at pull-off is recorded by a reset needle that is easily read on the large scale of the pressure gauge.
Connection to the stainless steel Dolly is easily made with a snap-on connector.
The pressure gauge is swivel-mounted allowing testing in any position.
This is significant as coating breakdown invariably starts at positions that were difficult to reach during surface preparation and application.
Can test both external and internal surfaces of pipes.
Because the load is reacted internally within the Dolly, curved surfaces of pipes can be easily tested.
To obtain a uniform tensile load, curved Dollies machined to match the diameter under test need to be used.
External diameters as small as 25mm (1”) and internal diameters as small as 150mm (6”) can be tested.
Ensures effective quality control with a non-destructive capability.
To allow the specification minimum to be proven the Dolly can be removed using the heated Dolly remover supplied.
If necessary, the Dolly can be left in place for testing during service as part of a planned maintenance programme.
Calibration certificates with traceability to UKAS are an optional extra.
The certificates are supplied as hard copy and are available online through the Calibration Portal (under Browse Categories) on our website.
The Calibration Portal will list all your equipment calibrated by Paint Test Equipment, showing the renewal dates and allowing calibration certificates to be viewed at any time.
Supplied in an Industrial Foam-Filled Carrying Case with 5 Flat Dollies, Adhesive, Heated Dolly Remover, Dolly Cleaning Tool and Dolly Plug.
