1.1 These methods are used to determine the effectiveness of procedures and agents for inactivating (neutralizing, quenching) the microbiocidal properties of antimicrobial agents and to ensure that no components of the neutralizing procedures and agents, themselves, exert an inhibitory effect on microorganisms targeted for recovery.

Note 1—Knowledge of microbiological and statistical techniques is required for these procedures. These methods are not applicable to testing with viruses (see Test Method E 1482).

1.2 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.
