A number in parentheses indicates the year of last reapproval. Such agage is applicable to coatings on flat substrates and to coatingson articles of various sizes and complex shapes where it ispossible to get the end tabs of the gage to rest in the same planeon the substrate. Such a gage is applicable to coatingson flat substrates and to coatings on objects of various sizes andcomplex shapes. The values given in parentheses are for informationonly.

More D Most protective and high performance coatings are applied to meet a requirement or specification for dry film thickness for each coat or for the completed coating system, or for both. With some flat coatings the dry film thickness is higher than that calculated from the wet film thickness.

Consequently, the results from the notch gage are not to be used to verify the nonvolatile content of a coating. Correction of the film after it has dried or chemically cured requires costly extra labor time, may lead to contamination of the film, and may introduce problems of adhesion and integrity of the coating system.

Notch gages may, however, be used on nonuniform surfaces, like concrete block, that are too rough to use the Interchemical and Pfund gages. 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. Examples of such items are ellipses, thin edges, and corners.
