This may be considered to be a nondestructive test because of the relatively low voltage.
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. Please login to your authorized staff account to use this feature. It is effective on films up to 0.
ASTM G62 – 07 Standard Test Methods for Holiday Detection in Pipeline Coatings
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 v62. Plug the searching electrode into the holiday detector.
When a holiday is picked up by the audible alarm, the electrode can be turned on end and the exact spot of failure can be noted by searching with the tip of the electrode. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. This may be considered to be a nondestructive test because of the relatively low voltage. Now touch the electrode to a second point where the surface is bare and note that the audible signal will be activated.
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.
