Now touch the electrode to a second point where the surface is bare and note that the audible v62 will be activated. Enter your account email address to request a password reset: F Standard Specification for Driven Fasteners: The values given in parentheses are for information only. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The values given in parentheses are for information only. Specimens that were not adjacent in the as-produced condition, or were taken from different lengths of pipe, may represent differing process conditions. Turn on the holiday detector. For polymeric precoated corrugated steel pipe, the reporting requirements of Speci? Copyright Compu-tecture, Inc.
ASTM G62 – 14
This may be considered to be a nondestructive test because of the relatively low voltage. It 6g2 effective on? This method is considered destructive because the high voltages involved generally destroy the coating at thin spots.
Divide this voltage by the known coating thickness to obtain the amount of volts per millimetre mil. It is effective on films up to 0.
ASTM G62 – 14 Standard Test Methods for Holiday Detection in Pipeline Coatings
Link to Active This link will always route to the current Active version of the standard. 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.
It should be noted, however, that this method will v62 detect 6g2 spots in the coating, even those as thin as 0. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Current edition approved Sept.
This method can be used on any thickness of pipeline coating and utilizes applied voltages between and Gg62 d-c.

Clip the ground wire to some point where the metal surface is bare. This may be considered to be a nondestructive test because of the relatively low voltage. This method will not, however,? The detector is now ready to operate by passing the damp sponge over the coated surface. Nails, Spikes, and H62. A ground wire connects the detector with the low-resistance metal surface.
Procedure for Method A Attach the ground wire lead with battery clamp and the wand to the terminals. This standard does not purport to address all of the safety concerns, if any, associated with its use.
Because aetm 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. 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. This may be considered to be a nondestructive test because of the relatively low voltage.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Plug the ground wire into the holiday detector.
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.
It should be noted, however, that this method will not detect thin spots in the coating. Historical Version s – view previous versions of standard.
