The wall thicknesses and tolerances at the area of fusion shall be as shown in Table 3, Table 4 d3621 Table 5 of this specification.
We have no amendments or corrections for this standard. Size px x x x x For diameters not shown in Table 1 or Table 2, the tolerance shall be the same percentage as that shown in the corresponding tables for the next smaller listed size.
ASTM D3261 (1997)
Test specimens shall be prepared for testing in the manner described in Workmanship, Finish, and Appearance 8. The hydrostatic pressure shall be increased at a uniform rate such that the test pressure is reached within 60 to 70 s from the start of the test. The producer may use his asrm or any other suitable facilities for the performance of the inspection and test requirements specified herein, unless the purchaser disapproves.
When the fittings are to be installed under a system specification such astmm Specification D for gasaetm minimum requirements of that specification must be satisfied. Current edition approved Aug. Fiber stress of psi The test equipment and procedures shall be as specified in Test Method D Your Alert Profile lists the documents that will be monitored. The test specimens shall be prepared for testing in the manner prescribed in Already Subscribed to this document.
For those SDR groups having overlapped thickness requirements, a manufacturer may represent their product as applying to the combination for example, Please copy and paste this embed script to where you want f3261 embed Embed Script.
The fittings shall be as uniform as commercially practicable in color, opacity, density, and other physical properties. The test equipment, procedures, and failures definitions shall be as specified in Test Method D DRs are rounded and do not calculate exactly.
Test methods that are applicable from other specifications will be referenced in the paragraph pertaining to the particular test.

This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn.
Originally published as D — NOTE 1—Other test mediums and test conditions than offered in Table 7 may be used as agreed upon between asfm manufacturer and the purchaser. Government uses or endorses the products described in this specification.
A fitting is unacceptable no go if it fits snugly on the minimum inside diameter land of zstm gage or if it fits loosely on the maximum diameter land of the gage. Fittings shall be homogeneous throughout and free of cracks, holes, foreign inclusions, or other injurious defects. Included are requirements for materials, workmanship, dimensions, marking, d32661 pressure, and burst pressure. A number in parentheses indicates the year of last reapproval. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters.
Make a minimum of six measurements at each cross section. The hydrostatic pressure shall be increased at a uniform rate such that the specimen fails between 60 and 70 s from start of test.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. For this specification it is calculated by dividing the specified outside diameter by the specified wall thickness of the fitting at its area of fusion.
As the voice of the U. For those SDR groups having overlapping thickness requirements, a manufacturer may represent their product as applying to the combination for example, These dimensions and tolerances shall be as shown in Table 1 and Table 2 of this specification.
At least one piece of pipe or tubing in the system shall have a minimum length equal to five pipe asrm. Standards Subsctiption may be the perfect solution.
Included are requirements for materials, workmanship, dimensions, marking, sustained pressure, and burst pressure.
