Significance and Use | ||||||||||||||||||||
This test method is used for the determination of trace levels of lead in nickel alloys by GF-AAS to check compliance with compositional specifications. 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. Appropriate quality control practices must be followed such as those described in Guide E 882. |

1. Scope | ||||||||||||||||||||
1.1 This test method covers the determination of lead in nickel alloys in the concentration range 0.00005 % to 0.001 % by graphite furnace atomic absorption spectrometry (GF-AAS). Note 1—If this test method is used to test materials having contents less than 0.0001 % lead, users in different laboratories may experience more than the usual 5 % risk that their results will differ by more than 50 % relative error. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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. For specific hazards associated with the use of this test method, see Practices E 50. |
