Your Alert Profile lists 2b49 documents that will be monitored. To determine compliance with this tolerance, the lengths shall, in case of disagreement, be checked by the following method: Products shall be manufactured by hot working, cold working, or both, and finished by cold working, annealing, or heat treatment and straightening as xstm necessary to meet the properties specified.

Local departure from b429 should be measured with a 1-ft [mm] straightedge and a feeler gage. Alternatively, a lot shall be the product of one cast bar from a single melt charge, or one continuous casting run whose weight does not exceed 40 lbs [20 kg] that has been continuously processed and subject to inspection at one time.

They are subject to minimum length and maximum weight requirements. Packaging and Package Marking 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.

This specification establishes the general requirements common to wrought copper and copper alloy rods, bars, shapes, and forgings. Within the text the SI values are given in brackets. If the pH value is not speci?
