ASTM D3645 – Standard Test Methods for Beryllium in Water
Description:
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 μg/L to 500 μg/L | 7 to 17 |
| Test Method B–Atomic Absorption, Graphite Furnace | 10 μg/L 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.
