This test method covers the determination of certain polychlorinated biphenyls (PCBs) including: Aroclors 1221, 1232, 1242, 1248, 1254, 1260, and 1016.
Formerly under the jurisdiction of Committee D19 on Water, this test method was withdrawn in December 2003 in accordance with section 10.6.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
1.1 This test method covers the determination of certain polychlorinated biphenyls (PCBs) including: Aroclors 1221, 1232, 1242, 1248, 1254, 1260, and 1016.
1.2 The detection limit is in the range from 0.1 to 0.5 [mu]g/L for Aroclor 1254 and 1260 when analyzing 1 L of water using an electron capture detector. The detection limit is compound dependent and is also determined by instrumental sensitivity and interferences present. When using a microcoulometric or conductivity detector, the detection limit is approximately 1.0 [mu]g/L.
1.3 Precision and bias statements reflect recovery of PCB products dosed into water samples. These statements may not apply to environmentally altered PCBs.
1.4 As the precision and bias statements given may apply only to waters used, it is the user's responsibility to ensure the validity of the test method for waters of untested matrices.
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.
1.6 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 a specific hazard statement, see Note 2.
