Standard Test Methods for Beryllium in Water

Fecha:
2017-02-22 /Active
Significance and Use:

4.1 These test methods are significant because the concentration of beryllium in water must be measured accurately in order to evaluate potential health and environmental effects.

Scope:

1.1 These test methods cover the determination of dissolved and total recoverable beryllium in most waters and wastewaters:

 

Concentration
Range


Sections

Test Method A–Atomic Absorption,  Direct

10 to 500 μg/L

7 to 17

Test Method B–Atomic Absorption,  Graphite Furnace

10 to 50 μg/L

18 to 26

1.2 The analyst should direct attention to the precision and bias statements for each test method. It is the user's responsibility to ensure the validity of these test methods for waters of untested matrices.

1.3 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.

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. For specific hazard statements, see Section 12 and 24.4.
