In the paint and coating industries, paint adhesion testing is often used to determine if the paint or coating will adhere properly to the substrates to which they are applied. Several tests measure the resistance of paints and coatings from substrates: cross-cut test, scrape adhesion, pull-off test , and others.
A test patch should be as clean as possible. Contamination of a patch can influence the results significantly. Bresle patch injected with 15ml water as in ISO 8502-6 Annex A. The ISO 8502-6 standard prescribes in annex A that certified patches shall be used. This annex describes a stress test to ensure patch adhesion and wash ability.
Gardco signature Zahn cups and Gardco EZ Zahn cups use different conversions. [1] Ascott Zahn Cups are based on measuring the Flow of liquid in seconds. Results should be reported in Zahn-Seconds at a specified temperature for a particular cup. [2] To convert Zahn-Seconds to centistokes, refer to ASTM D4212, D816, and D1084

The salt spray test (or salt fog test) is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings.Usually, the materials to be tested are metallic (although stone, ceramics, and polymers may also be tested) and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal.
