Standard Test Method for Measurement of Film Thickness of Thin-Film Coatings by Non-Destructive Means Using Ruggedized Optical Interference

Importancia y uso:

4.1 Coating film thickness plays a critical role in the performance of the final product. This includes physical properties (abrasion/scratch resistance, color, gloss), chemical properties (solvent resistance), corrosion resistance, and long-term durability (color change, chalk, fade).

4.2 The non-destructive measurement system based on ruggedized optical interference transforms signal outputs in coating film thickness using digital formulas (or “recipes”) which are reproducible from one instrument to another.

4.3 The ROI measurement unit takes a significant number of measurements which can be read in a determined period of time and each of these data points is recorded and reportable.

4.4 Due to the number of variables that can affect film thickness during application and the number of variables that must be set in the measurement unit while determining a recipe, it is important for the producer and the user to agree upon recipe settings depending on the coating system.
