Standard Test Method for Hydrophobic Contamination on Glass by Contact Angle Measurement
2020
3
ASTM Vol.15.02 (2022)
The contact angle test is nondestructive and may be used for control and evaluation of processes for the removal of hydrophobic contaminants. The test may also be used for the detection and control of hydrophobic contaminants in processing ambients. For this application, a surface free of hydrophobic films is exposed to the ambient conditions and is subsequently tested.
