This method will not, however, find any thin spots in the coating. Therefore, they are useful for testing voids, pinholes and thin spots in the coating, but would not be useful as a coating thickness quality control tool. Reagents and Materials 7. Nails, Spikes, and Staples. Clip the ground wire to some point where the metal surface is bare.

ASTM G (Reapproved )e1_百度文库

A g662 factory setting for sensitivity is V. This method can be used to verify minimum coating thicknesses as well as voids in quality-control applications. This may be considered to be a nondestructive test because of the relatively low voltage. Search book title Enter keywords for book title search.

These are used on the coatings of relatively high-electrical resistance when such coatings are applied to the surface of materials of low-electrical resistance, such as steel pipe. It should be noted, however, that this method will not detect thin spots in the coating.

This method is considered destructive because the high voltages involved generally destroy the coating at thin spots. Dryness is critical in a high voltage test. Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Divide this voltage by the known coating thickness to obtain the amount of volts per millimetre mil. When a holiday is detected by the audible alarm, the electrode can be repositioned to determine the exact holiday area by observing the origin of the spark jump. The values given in parentheses are for information only. The detector will ring if it passes any void, pinhole, or area of the coating thinner than the minimum allowable thickness.
