The Calibration Portal will list all your equipment that is calibrated by Paint Test Equipment, showing the renewal dates and allowing Calibration Certificates to be viewed at any time. The Certificate is supplied in a paper format and is available online through the Calibration Portal (under Browse Categories) on this website. If necessary, the Dolly can be left in place for testing during service as part of a planned maintenance program.Ĭalibration Certificate with traceability to UKAS (for the Adhesion Tester) and PAT Certificate (for the Heated Dolly Remover) are an optional extra. To allow the specification minimum to be proven, the Dolly can be removed using the heated Dolly remover supplied. External diameters as small as 25mm (1") and internal diameters as small as 150mm (6") can be tested.Įnsures effective quality control with a non-destructive capability.
To obtain a uniform tensile load, curved Dollies machined to match the diameter under test need to be used. Because the load reacts internally within the Dolly, curved surfaces of pipes can be easily tested. The Adhesion Tester can test both external and internal surfaces of pipes. This is significant as coating breakdown invariably starts at positions that were difficult to reach during surface preparation and application. The pressure gauge is swivel-mounted allowing testing in any position. 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.Ĭonnection to the stainless steel Dolly is easily made with a snap-on connector. Pressure reacted by the Dolly is the same as the pressure in the bore and is transmitted directly to the pressure gauge. This is made possible as the net surface area of the Dolly is equal to the surface area of the hydraulic piston bore. This ensures an exactly central point-loading of the force.Īdhesion values are recorded by a pressure gauge giving a 1:1 pressure reading. The force is applied through the centre of the Dolly by a hydraulically loaded pin. The adhesion is measured by the tensile pull on a Dolly glued to the coating surface. It measures the adhesion bond strength of applied coatings with ease, and precision. The Hydraulic Adhesion Tester is one of the most accurate and versatile adhesion testers currently available.
