The objective of this Standard is to provide the electrotechnology industry with a complete set of environmental test procedures published as a series under AS 60068 Environmental testing. This Standard is Part 2.70 of that series.

This International Standard provides a standard method to determine the resistance of markings and letterings on flat or curved surfaces against abrasion as may occur for example by manually operating actuators and keyboards. The method is also suitable to test the resistance against fluid contamination as may occur under normal use.
