NOTE 3—Blank spaces in the tolerance tables indicate either that the material generally is not available or that no tolerances are established. Cand B We have no amendments or corrections for this standard.
Materials shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional mass, diameter, length, straightness, and edge contoursmechanical tensile strength, Rockwell hardness, elongation, and hydrogen embrittlementelectrical resistivity, chemical composition, and grain size requirements.
Local departure from straightness should be measured with a 1-ft [mm] straightedge and a feeler gage. NOTE 1—The length tolerances in this table are all plus; if all minus tolerances are desired, use the same values; if tolerances are desired plus and minus, halve the values given.
