ASTM-E738 › Standard Test Method for Determination of Aluminum in Iron Ores and Related Materials by EDTA Complexometric Titrimetry (Withdrawn 2020)
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers the determination of aluminum in iron ores, concentrates, and agglomerates in the compositional range from 0.25 % to 5 % aluminum.
Note 1—As used in this test method (except as related to the term relative standard deviation), “percent” or “%” refers to mass fraction (wt/wt) of the form g/100g.
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.
Significance and Use
This test method for the analysis of iron ore concentrates and agglomerates is primarily intended as a referee method to test for compliance with compositional specifications. It is assumed that all who use this test method will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory and that proper waste disposal procedures will be followed. Appropriate quality control practices shall be followed, such as those described in Guide E882.
