1.1These test methods cover the determination of zinc in water. Two test methods are given as follows:
Test Method | Concentration Range | Sections |
A—Atomic Absorption, Direct | 0.05 to 2 mg/L | |
B—Atomic Absorption, | 20 to 200 μg/L |
1.3These test methods have been used successfully with reagent grade water. See the specific test method for applicability to other matrices. It is the user's responsibility to assure the validity of these test methods in other matrices.
1.4The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are mathematical conversions and may not be exact equivalents; therefore, each system shall be used independently of the other.
1.5This 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 hazard statements, see Section 6 and Note 6, Note 10, and Note 16.
1.6Two former colorimetric test methods were discontinued. Refer to Appendix X1 for historical information.
