Standard Test Methods for Iron in Water
 N D1068

Annotation

These test methods cover the determination of iron in water. Procedures are given for determining total iron, dissolved iron, and ferrous iron. Undissolved iron may be calculated from the total iron and dissolved iron determinations.

It is the user’s responsibility to ensure the validity of these test methods to waters of untested matrices.

The chelation-extraction and two former photometric test methods were discontinued. See Appendix X2 for historical information.

The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.

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. Specific hazards statements are given in Note 4, 11.7.1, and X1.1.2.
