Disinfectant testing

Three basic kinds of testing for disinfectants. The first phase is carried out on a normal surface. Phase two evaluates the chemical disinfectants in more specific conditions. Both kinds are separated into two phases, each of which assesses a different aspect of the disinfectant's efficacy. In Phase 2 it is the time to introduce dirty conditions. The first test is conducted prior to the second phase, and it is vital to keep in mind that test results from the previous test may not reflect the results of the second phase.

The EPA has issued a draft guidance document in response to these modifications. The document provides changes to the testing procedures and labeling requirements. It also outlines new requirements for labeling and the test guidelines. The EN14476 draft guidance document was criticized by specialists in infection prevention which questioned the inclusion of wording relating to objects that are highly touchable. Therefore, the testing methods will have to be rewritten. The modifications will require further investigation and refinement in order to satisfy what the needs of users of disinfectants.

The ASTM E2967-15 test assesses the antimicrobial qualities from disinfectant wipes. It employs a multi-stage procedure that was developed by Williams et al., which is more complex than the prior protocol.
