Box Syracuse, NY U. Need more than one copy? Caltech’s wet film thickness gauge is designed to measure accurate liquid coating thickness in the easiest and fastest manner.
How to Use a ‘Wet Film Thickness’ Gauge
The substrate surface may also be examined for ‘drag’ marks left by the teeth asrm notches to confirm the values read from the notches or teeth. See dimensional drawing below.
You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Model A Gauges The gauges are precision manufactured from hardened grade stainless steel. This standard is also available to be included in Standards Subscriptions. The values given in parentheses are for information only. The gauges are precision manufactured from hardened grade stainless steel. As the voice of the U. Wet Film Thickness Gauges are designed to quickly and easily measure the thickness of coatings immediately after they have been applied to a substrate.

Wait several seconds to allow the teeth or aztm of the gauge to become ‘wetted’ by the coating, then withdraw the gauge vertically keeping it at ninety degrees to the substrate. How to Use a ‘Wet Film Thickness’ Gauge Wet Film Thickness Gauges are designed to quickly and easily measure the thickness of coatings immediately after they have been applied to a substrate.
Also notched gages can be very useful in the shop and field for determining the approximate thickness of wet films over commercial articles where size s and shape s are not suitable for measurements by other types of gages.

ASTM D – 95() Standard Practice for Measurement of Wet Film Thickness by Notch Gages
Zstm a gage is applicable to coatings on flat substrates and to coatings on articles of various sizes and complex shapes where it is possible to get the end tabs of the gage to rest in the same plane on the substrate. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
These different distances represent the surface of the wet coating thickness to be measured.
The gauges incorporate a s4414 of notches cut into their sides much like the teeth on a comb. Wet film thickness is measured to determine the correct dry coating thickness.
Standards Subsctiption may be the perfect solution.
Proceed to Checkout Continue Shopping. A ‘drag’ mark would indicate that the tooth or notch should have coating ‘clinging’ to it. These gauges meet the requirements of the following International Standards: The overall size of the gauges is 2.
Notch gages may, however, be used on nonuniform surfaces, like concrete block, that are too rough to use the Interchemical and Pfund gages. If the document is revised or amended, you will be notified by email. Be sure to clean the gauge with an appropriate solvent after use. All markings and graphics are etched and black filled.
The teeth or notches on each side of the gauge are referenced to each other. The ends of the teeth or notches are visually examined, some will be coated or ‘wet’ and some will not be coated or ‘wet’. The values given in parentheses are for information only. With some flat coatings the dry film thickness is higher than that calculated from the wet film thickness.
