标准范围
This International Standard specifies a destructive method for determination of the dry film thickness,in which damage to the coat caused in a definite manner is evaluated microscopically. The method issuitable for almost all coat-substrate combinations and also allows determination of the single filmthicknesses of coating systems.The method cannot be applied or can only be applied with restrictions in case of— too soft and/or elastic coatings (no recognizable scribe or drill hole can be observed),— hard (cannot be scribed/drilled) or too soft and/or elastic substrates,— too low visual contrast between the coating and substrate, and— film thicknesses that are larger than the depth of field of the measuring microscope.
