Q. What is a “water-break failure” test? M.N.

A. This also is called a “water-break-free” test. After the parts go through the detergent cleaning (acid or alkaline) and are rinsed in clean water, the rinse water should evenly coat the entire surface of the parts when they are lifted out of the rinse tank. If there is any contamination in the form of oils or other soils, the water will separate around those areas that are not clean, showing a “break” in the water surface on the parts. In this case, it would not be a surface free from water-breaks. This could be termed a “water-break-free-test failure.”
