Standardization of Instruments 9. Reagents and Materials 7. Attach the ground wire lead with battery clamp and the wand to the terminals.
NOTE 2—The dielectric breakdown voltage per millimetre mil can be determined for each coating experimentally as follows: Enter your personal account email address to request a password reset: Dryness is critical in a high voltage test. It is effective on films up to 0. Please login to your authorized staff account to use this feature. The values given in parentheses are for information only. It should be noted, however, that this method 6g2 not detect thin spots in the coating.
Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
Land Use and Development. Originally published as G 62 — Register for a trial account.
No items in cart. 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. Copyright Compu-tecture, Inc.
Today, some 12, ASTM asym are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence. Link to Active This link will always route to the current Active version of the standard. F Standard Specification h62 Driven Fasteners: 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 electrical contact will activate an alarm alerting the operator of the incidence of a holiday. This book also exists in the following packages Nails, Spikes, and Staples. Turn on the holiday detector.
ASTM G62 – 07 Standard Test Methods for Holiday Detection in Pipeline Coatings
Historical Version s – view previous versions of standard Translated Version s: Your comments will receive careful consideration at a aetm of the responsible technical committee, asrm you may attend.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? It is effective on films up to 0. Specimens that were not adjacent in the as-produced condition, or were taken from different lengths of pipe, may represent differing process conditions.
Divide this voltage by the known coating thickness to obtain the amount of volts per millimetre mil. Summary of Test Methods 4. Procedure for Method A Print 1 2 3 4 5 page sstarting from page current page. This standard does not purport to address all of the safety concerns, if any, associated with its use.
Are you sure you want to empty the cart? A number in parentheses indicates satm year of last reapproval.
ASTM G62 – 14
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 is effective on films up to 0. Active view current version of standard. 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.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It should be noted, however, that this method will not detect thin spots in the coating.
This method will determine the existence of any gross faults in thin-? This type of holiday detector will not detect thin spots in pipeline coatings.
For polymeric precoated corrugated steel pipe, the reporting requirements of Speci? If you like to setup a quick demo, let us know at support madcad. Clip the ground wire to some point where the metal surface is bare. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
This method is considered destructive because the high voltages involved generally destroy the coating at thin spots. This method can be used on any thickness of pipeline coating and utilizes applied voltages between and 20 V d-c. This may be considered to be a nondestructive test because of the relatively low voltage.
