Resilient foils should be avoided if possible. A probe is placed directly on the coated surface in a perpendicular position and electronic circuitry is used to convert a reference signal into a coating thickness measurement.

This standard has been approved for use by agencies of the Department of Defense. NOTE 1—Although, theoretically, this test method can be used for measuring nonconductive coatings on a magnetic basis metal, asym use for coatings below 25?

There is no standard time interval for re-calibration, nor is one absolutely required, but a calibration interval can wstm established based on experience and the work environment. A one-year calibration interval is a typical frequency suggested by many instrument manufacturers.

Factors Affecting the Measuring Accuracy 8. Local variations in coating thickness may also require that a number of measurements be made in any given area; awtm applies particularly to a rough surface see 8. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Foils are subject to indentation and should, therefore, be replaced frequently.

Hull Cells The Kocour Hull Cell is unmatched for its sturdy construction, durability and ease of use. Website by Distant Horizon. They are advantageous for adjustments n244 curved surfaces, and are more readily available than coated standards. Therefore, measurements made too near an edge or inside corner will not be valid unless the instrument is speci?
