Active view current version of standard. NOTE 2—The dielectric breakdown voltage per millimetre mil can be determined for each coating experimentally as follows: Because of the high voltages involved, do not touch the ground wire and the metal part of the electrode at the same time if the instrument is on.

Originally published as G 62 — This electrical contact will activate an alarm alerting the operator f62 the incidence of a holiday. This method can be used to verify minimum coating thicknesses as well as voids in quality-control applications. A ground wire connects the detector with the low-resistance metal surface.

This method will not, however,? This may be considered to aetm a nondestructive test because of the relatively low voltage.

No items in cart. Attach the ground wire lead with battery clamp and the wand to the terminals. Land Use b62 Development. Dryness is critical in a high voltage test.

Are you sure you want to empty the cart? This method can be used to verify minimum coating thicknesses as well as voids in quality-control applications.

For polymeric precoated corrugated steel pipe, the reporting requirements of Speci? Procedure for Method B 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.

Take care to keep the electrode at least This may be considered to be a nondestructive test because of the relatively low voltage.

It is effective on films up to 0.

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.
