Standard Test Methods for
Beryllium in Water1

This standard is issued under the fixed designation D 3645; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
a superscript epsilon (e) indicates an editorial change since the last revision or reapproval

1. 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 16
Test Method B–Atomic Absorption,
Graphite Furnace
10 to 50 µg/L 17 to 25

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 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 Sections 12 and 23.4.
