Technical Paper: Gage R&R for Contact Angle Measurements
Because most Gage R&R methods do not account for within-part variability, a modified approach is needed to properly determine the repeatability and reproducibility of contact angle measurements across parts and across operators.

How Many Measurements Are Enough to Make Quality Decisions?
A surface that has been properly prepared for coating, painting, or adhesive bonding will have a certain average contact angle that is determined primarily by the chemical composition of the surface. Because of slight variations in the surface composition combined with the variation inherent in any...
