Divide astj voltage by the known coating thickness to obtain the amount of volts per millimetre mil. It should be noted, however, that this method will not detect thin spots in the coating, even those as thin as 0.
ASTM G62 – 07 Standard Test Methods for Holiday Detection in Pipeline Coatings
No items in cart. This method can be used to verify minimum coating thicknesses as well as voids in quality-control applications. Register for a trial account. Current edition approved Sept. It is effective on films up to qstm. A superscript epsilon e indicates an editorial change since the last revision or reapproval. A number in parentheses indicates the year of last reapproval. If the surface is in an environment where electrolytes might form g662 the surface, such as salt spray, wash the coated surface with fresh water and allow to dry before testing.
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. Take care to keep the electrode at least Specimens that were not adjacent in the as-produced condition, or were taken from different lengths of pipe, may represent differing b62 conditions.
NOTE 1—Ordinary tap water will suffice to wet the sponge electrode when inspecting coatings up to 0. Then tighten the clamps with the screw until they are well down into the sponge electrode. Summary of Test Methods 4. This book also exists in the following packages This method will not, however,? Increase the holiday detector voltage over aztm known coating thickness and measure the voltage at the point where the detector will astj begin to ring.
Most units can be reset to any predetermined sensitivity value in this manner. A common factory setting for sensitivity is V.
This may be considered to be a nondestructive test because of the relatively low voltage. Click here to download full list of books.
This may be considered to be a nondestructive test because of the relatively low voltage. Originally published as G 62 — 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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Are you sure you want to empty the cart? Take care to keep the electrolyte at least Link to Active This link will always route to the current Active version of the standard. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. This method can be used to verify minimum coating thicknesses as well as voids in quality-control applications.
ASTM G62 – 14
NOTE 2—The dielectric breakdown voltage per millimetre mil can be determined for each coating experimentally as follows: 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.
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. This is particularly important if formed surfaces are to be inspected.
Standardization of Instruments 9. Turn v62 the holiday detector.
This method will determine the existence of any gross faults in thin-? Historical Version s – view previous versions of standard Translated Version s: The detector will ring if it passes any void, pinhole, or area of the coating thinner than the minimum allowable thickness. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. This method will determine the existence of any gross faults in thin-film pipeline coatings.
This method will not, however, find any thin spots in the coating. It is effective on?
It is effective on films up to 0. Plug the searching electrode into the holiday detector.
