This test method is to be used for the determination of trace levels of antimony in carbon and low-alloy steel. It is assumed that the procedure will be performed by trained analysts capable of performing common laboratory practices skillfully and safely. It is expected that the work will be performed in a properly equipped laboratory and proper waste disposal procedures will be followed.

1.1 This test method covers the determination of antimony in carbon and low-alloy steel in the 0.0005 through 0,010% range.

1.2 If this test method is used to test materials having contents less than 0.001% antimony, users of different laboratories will experience more than the usual 5% risk that their results will differ by more 50% relative error.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
