TEST PROCEDURE

Before you start, ensure the wet film comb or wheel is clean, see Section 3.3 ‘Cleaning After Test’ on page en-4, and undamaged as damage to the wet film teeth or wheel circumference will affect the readings.

USING A WET FILM COMB

1. Hold the comb perpendicular to the wet film and press the edge of the comb into the film until it is stable on the substrate.
2. Remove the comb from the wet film.
3. Examine the teeth of the comb and locate the last tooth which is wetted.
   Read the thickness value of this tooth. The wet film thickness is between this value and the thickness value of the next dry tooth.

In the example shown, the wet film thickness lies between 2400μm and 2600μm.To use the comb on pipes, ensure it is placed parallel to the longitudinal axis of the pipe.

On rough surfaces, measurements will be made from the surface peaks and therefore will represent the minimum wet film thickness.

b A storage wallet/case is not supplied with the Elcometer 112AL and Elcometer 154.
c Calibration certificates are not available for the Elcometer 112AL, Elcometer 154 and Elcometer 3230 Coil Coating Wet Film Wheels.

USING A WET FILM WHEEL

The procedure outlined below is for guidance only. Consult the relevant Standard for full details of the applicable test procedure.

1. Using a finger and thumb, hold the wheel by its central spindle with the maximum reading on the scale nearest to the paint film.
2. Place the wheel into the wet film ensuring that the wheel is perpendicular to the film.
3. Roll the wheel across the film through 360°/180° (depending upon standard) and then remove it from the surface.
4. Locate the first point on the central wheel where the paint has adhered. Read the wet film thickness from the scale on the side of the wheel at this point.

Repeat the procedure at least twice in different places to obtain representative results.
To use the wheel on pipes, roll the wheel at right angles to the longitudinal axis of the pipe.
On rough surfaces, measurements will be made from the surface peaks and therefore will represent the minimum wet film thickness.

CLEANING AFTER TEST

Clean the wet film comb or wheel after each test using a suitable solvent. After cleaning, ensure that all materials are removed and that the gauge is dry.

DO NOT use very aggressive solvents or wire brushes, metal scrapers, metal files, or other metallic tools for cleaning.

Store the wet film comb or wheel in the wallet/case provided when not in use.

b A storage wallet/case is not supplied with the Elcometer 112AL and Elcometer 154.
d Does not apply to the Elcometer 154 which are designed to be used once and kept as a record of wet film thickness measurement for quality assurance or customer requirements.
