Overview
Coating inspection and surface testing services can be performed on a variety of applications, which include paints, fibreglass, epoxy coverings, lacquers and metallic coatings. Inspectors are certified by either the ACA, NACE or BGAS and have excellent knowledge of preparation, cleaning and coating applications.
Blasting And Cleaning Surface Checks
Substrate tests are performed before the application of coatings. These tests include;
- Testing for salts
- Testing for impurities.
- Testing for cleanliness
- Testing surface profile
Tests are conducted in accordance with various Australian and International Standards as applicable.
Coating Thickness Testing
Coating thickness testing is performed using electromagnetic gauges or eddy current equipment against certified calibration samples. Coating thickness up to 10.0mm can be checked on metals.
Tests are conducted in accordance with various Australian and International Standards as applicable.
Holiday (Porosity) Testing
Our services have been used on storage tank linings, piping systems, underground tank coatings and other fabrications before installation or during service. Holiday testing, using either the high-voltage wire brush or low-voltage wet sponge technique, is available to locate porosity within coatings.
Pipe and tube brushes are also available for checking external or internal surfaces of coated pipes and tubes. Testing is performed in accordance with Australian and International Standards by our experienced staff.
Coating Adherence & Curing Tests
Our coating inspection capabilities include testing for adhesion to substrate, conducted in accordance with AS 3894 and similar International Standards.
Adhesion test methods include;
- Knife Tests
- Pull-Off Test
Knife text results are assessed by grading the nature/characterisation type and quality of removal of a particular coating.
Pull-off tests are assessed through both the tensile bond strength and the visual appearance of the coating, indicating the probable cause of apparent failure, whether due to disbonding from the substrate, cohesive issues within the coating, or intercoat adhesion.
Coating curing tests include assessing the degree of curing of various coatings using rub tests and specialised hardness tests in accordance with AS 3894 and similar International Standards.
