They may not be included with returns for remelting or machined into product. Government Contracts NOTE 1—If the number of original castings from which the material is processed is less aztm the number of samples specified, not more than one sample need be taken from each piece for chemical analysis. If used for that purpose, the results shall be for information only and not a cause for rejection of the assembly, its component parts, or the original mill product.
Test Methods the producer or supplier shall be responsible only for replace- ment of the material to the purchaser.
Note 2 — Test Method B may be considered as a possible alternative test method which does not involve the use of mercury. If used for that purpose, the results shall be for information only and not a cause for rejection of the assembly, its component parts, or the original mill product.
For any particular copper alloy, reference should be made h154 the material specification. Warning— Care should be exercised when handling and mixing chemicals. This test method is intended to cover the mercurous nitrate test of certain copper-alloy products supplied in accordance with ASTM speci?
