Paints and varnishes - Wedge-cut method for determination of film thickness (scribe and drill method) - First Edition
N 19399
Annotation
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 is suitable for almost all coat-substrate combinations and also allows determination of the single film thicknesses 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.

Краски и лаки - сокращенный Клином метод для определения толщины пленки (писец и метод тренировки) - Первый Выпуск
Этот Международный стандарт указывает разрушительный метод для определения сухой пленочной толщины, в которой ущерб слоя, вызванного определенным способом, оценен тщательно. Метод подходит для почти всех комбинаций подложки слоя и также позволяет определение одной пленочных толщин систем покрытия.
