A new instrumental approach for measurement of corroded surface area has been developed by AD Systems in which the exact percentage of corroded area is accurately determined by an automatic instrument reducing test subjectivity. The operation is based on a homogeneous lighting source, CCD camera, specimen rotation system, and specially designed application software. With CT10 the corrosion rating is now very repeatable and fully documented.
The CT10 test is simple and straight forward. The iron specimen is prepared according to the standard test procedure (using CB10 corrosion bath) and is placed in the test chamber of the CT10. The operator enters sample information, using an intuitive graphical interface with touch screen panel, and starts a specimen scan. The specimen is rotated in specially designed lighted chamber and several images are taken by digital camera. The software builds a flat image of the specimen suface, analyses it and calculates the percentage of the corroded area. This percentage is reported and translates it into a NACE rating.
A detailed test report is ready in less than 5 minutes.
