Rapid Testing Methods for Production Control

For some years now, special time-compressed corrosion tests based on recommendations made by European quality associations have become more established. The following are worthy of mention: condensation test, acid and neutral salt spray test, filiform corrosion tests and specific automotive test standards. Despite the demand to speed up tests, testing times of between 40 and 60 days are typical, thus rendering the tests irrelevant as far as real-time production control is concerned.

In this regard, rapid innovative corrosion tests are needed that enable potential corrosion protection errors to be anticipated within the space of one to three days. Appropriate short-term testing methods have to be developed as fast as possible in order to implement fast, realistic production control processes in the powder coating industry.
