A lot shall be all material poured from one heat.

When using small or subsize specimens, the largest one possible shall be used. An explanation of specication requirements to be completed is provided in In the case of conflict between a requirement of the product specification or a requirement of this specification and a more stringent requirement of the purchase order, the purchase order shall prevail. The standard sizes do not prohibit the production and use of other sizes of pipe produced to the various product specications referenced in 1.

NOTE 4—Notwithstanding the absence of a signature or notarization, the organization submitting the Report is responsible for the contents of the report. To be accepted, a repaired pipe must pass the same astk test by which it was rejected, and it must meet the minimum wall thickness requirements of the applicable product specication. Only one retest of any lot will be permitted.

The chemical composition thus determined, or that determined from a product analysis made by the tubular product manufacturer shall asgm to the requirements specied. Unless otherwise specied, pipe of NPS 4 and smaller s999 be weighed in convenient lots; pipe in sizes larger than NPS 4 shall be weighed separately.


Nondestructive Test Requirements In the case of conict between a requirement of the product specication or a requirement of this specication and a more stringent requirement of the purchase order, the purchase order shall prevail.

Terms of Sale Privacy Policy.

Surface imperfections such as handling marks, straightening asrm, light mandrel and die marks, shallow pits, and scale pattern will not be considered injurious if the imperfections are removable within the tolerances specied for wall thickness or 0. The pipe may be accepted based on visual examination provided that the imperfection is less than 0.

Other nondestructive tests may be applied to the end areas, subject to agreement between the purchaser and the manufacturer.

Disposition of such pipe shall be matter for agreement. The width of the notch shall not exceed twice the depth.

During the rst step, which is a test for ductility, no cracks or breaks on the inside or outside surfaces, except as provided for in Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

ASTM D e1. Notwithstanding the absence of a signature, the asfm submitting the EDI transmission is responsible for the content of the report. Defects shall be thoroughly chipped or ground out before welding and each repaired length shall be reheat treated or stress relieved as required by the applicable specication. Permissible Variations in Inside Diameter The values stated in each system are not exact equivalents; therefore each system is to be used independently of the other without combining a999 in any way.


The outside diameter at the point of grinding may be reduced by the amount so removed.

Current News Archive Standard Technically. Notches shall be placed on both the OD and ID surfaces. The purchaser shall have the right to perform any of the inspections and tests set forth when such inspections and tests are deemed necessary to aastm that the material to conforms to the prescribed requirements.

The sensitivity of this test decreases with thickness over 0.

For welded pipe, the test pressure shall be held for a time sufficient to permit the entire length of the welded seam to be inspected. Upon agreement between purchaser and manufacturer, Practice E shall be employed in addition to one of a999 full periphery tests.
