Copyright Compu-tecture, Inc. It is the responsibility of the user of this standard to establish appropriate safety and health astj and determine the applicability of regulatory limitations prior to use.
This method will not, however,? This may be considered to be a nondestructive test because of the relatively low voltage. This is particularly important if formed surfaces are to be inspected.
Increase the holiday detector voltage over a known coating thickness and measure the voltage at the point where the detector will just begin to ring. Historical Version s – view previous versions of standard Translated Version s: NOTE 2—The dielectric breakdown voltage per millimetre mil can be determined for each coating experimentally as follows: This is used more commonly with Method B where voltage may vary from test to test but can also be used for veri?
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. Users of this standard are gg62 advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
It should be noted, however, that this method will not detect thin spots in the coating, even aastm as thin as 0. Print 1 2 3 4 5 page sstarting from page current page. 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 awtm steel pipe.

ASTM G62 – 14
It is effective on films up to 0. This electrical contact will activate an alarm alerting the operator of the incidence of ashm holiday. Nails, Spikes, and Staples. This method will determine the existence of any gross faults in thin-film pipeline coatings. Active view current version of standard.

ASTM G62 – 14 – Standard Test Methods for Holiday Detection in Pipeline Coatings
This method can be used to verify minimum coating thicknesses astk well as voids in quality-control applications. Click here to download full list of books. Standardization of Instruments 9. This method can be used on any thickness of pipeline coating and utilizes applied voltages between and 20 V d-c. 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.
This type of holiday detector will not detect thin spots in pipeline coatings. Are you sure you want to empty the cart?
