Historical Standard: ASTM D6530-00(2006) Standard Test Method for Total Active Biomass in Cooling Tower Waters (Kool Kount Assay; KKA)
SUPERSEDED (see Active link, below)
ASTM D6530
1. Scope
1.1 This test method covers the determination of viable active biomass in cooling tower water in the range from 10 2 to 10 8 cfu/mL (1). It is a semiquantitative test method.
1.2 This test method was used successfully with reagent water, physiologic saline, and cooling tower waters. It is the user's responsibility to ensure the validity of this test method for waters of untested matrices.
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 .
