Fecha:
2016-12-27 /Active
Significance and Use:

5.1 This test method is intended to be used for compliance with compositional specifications for phosphorus content. It is assumed that all who use these procedures 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.

Scope:

1.1 This test method covers the determination of phosphorus in iron ores, concentrates, and agglomerates.

1.2 This test method covers the determination of phosphorus in the range from 0.01 % to 1.00 %.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 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.
