Wet-film thickness gauges help determine how much material to apply wet to achieve a specified dry-film thickness provided that the percent of solids by volume is known. They measure all types of wet organic coatings, such as paint, varnish, and lacquer on flat or curved smooth surfaces.One of the most recognised, destructive methods in the coating industry is to use a paint inspection gauge (also referred to as a Tooke gauge or the PIG). The PIG is a popular method for determining dry film thicknesses on non-metallic substrates.. PIGs are available in various models. Some contain one cutter with an angled cutting edge suitable for a specific thickness .Film thickness is the measurement result, which is obtained from a coating according to an agreed, standardized, precisely described and carefully applied measuring method (Fig. 1). The DIN EN ISO 2808 [1] describes several methods for determining wet film thickness, dry film thickness, and the thickness of unbaked powder coatings.
Dry-film thickness can be measured either in a destructive or non-destructive manner. “Non-destructive paint thickness gauges generally fall into one of three categories,” reports David Beamish, general manager of DeFelsko Corp. in Ogdensburg, N.Y. Use “magnetic gauges for measuring over steel, eddy current gauges for measuring over most .3.1.8 dry film thickness, n—the thickness of a coating (or coating layers) as measured from the surface of the substrate. 3.1.8.1 Discussion— If the surface of the substrate is roughened, the dry film thickness is considered the thickness of the coating or coating layers above the peaks of the surface profile. 3.1.9 ferrous, n . 1.1 This practice describes the measurement of dry film thickness of coating films by microscopic observation of precision angular cuts in the coating film. Use of these procedures may require repair of the coating film. This practice is intended to supplement the manufacturers' instructions for the manual operation of the gages and is not intended to replace them.Ultrasonic coating thickness measurement is now an accepted and reliable testing routine used in wood industries. The standard test method is described in ASTM D6132. “Standard Test Method for Nondestructive Measurement of Dry Film Thickness of Applied Organic Coatings Using an Ultrasonic Gage” (2022, ASTM).
The measurement of film thickness holds significance for various manufacturing and research facilities. Fluctuations in the thickness of paint or coating can impact multiple properties crucial to the end product, including color, gloss, hardness, adhesion, and . 1.1 This test method covers the measurement of dry film thickness (DFT) of coating films by microscopic observation of a precision-cut, shallow-angle crater bored into the coating film. This crater reveals cross sectional layers appearing as rings, whose width is proportional to the depth of the coating layer(s) and allows for direct .ASTM D1005, Standard Test Method for Measurement of Dry Film Thickness of Organic Coatings Using Micrometers [26] ASTM D1212, Standard Test Methods for Measurement of Wet Film Thickness of Organic Coatings [27] ASTM D4414, Standard Practice for Measurement of Wet-film thickness by Notch Gages [28]
