significance And Use:

scope:

1.1 This test method describes a procedure for evaluating dry abrasion resistance of a thin hydrophobic or omniphobic coating, or both. The coating is typically less than 100 nm thick and is applied to a planar, glass substrate by application methods including, but not limited to, physical vapor deposition (PVD), dip, or spray.

1.2 Units-The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard with the exception of angular measurement which are reported in degrees.

Note 1: This test method measures a static contact angle and is not equivalent to Test Method C813 which measures an advancing contact angle.

Note 2: Test Method D4060 is not applicable to hydrophobic and omniphobic coatings because the molecular monolayer does not generally result in a detectable weight change to the specimen after subjecting it to abrasion.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
