Chemical disinfectants and antiseptics Phase I tests

Quantitative suspension tests to establish that a product has biocidal activity without regard to specific conditions of intended use.

Chemical disinfectants and antiseptics Phase II / step 1 tests

Quantitative suspension tests to establish that a product has biocidal activity simulating practical conditions appropriate to its intended use.

Chemical disinfectants and antiseptics Phase II / step 2 tests

Quantitative laboratory tests simulating practical conditions e.g. surface, instruments, handwash and handrub tests.
