Corrosion test methods. The salt spray test : towards new specifications

摘要

In spite of its shortcomings, the salt spray test is universally used to characterize the corrosion resistance of zinc based coatings. A working group has tried to improve its reliability by the introduction of a now calibration method of the equipment. The outcome of the work is the definition of a new testing procedure, presently adopted in France for the control of coated products delivered to the automobile industry.
