PHASE

TEST TYPE

PURPOSE

Phase 1

Quantitative suspension test
under unsoiled conditions for basic activity

To establish that a product has bactericidal and/or fungicidal activity
without regard to specific conditions of intended use.
If the product passes, it qualifies for further testing

Phase 2
Step 1

Quantitative suspension test under conditions
representative of practical use

To establish that a product has bactericidal, and/or fungicidal, and or sporicidal,
and/or virucidal, and/or tubercolocidal, and so forth, activity under conditions
appropriate to its intended use in laboratory conditions.
If the product passes, it qualifies for generic disinfectancy claims.

Phase 2
Step 2

Quantitative surface test under conditions
representative of practical use

Further laboratory test such as hand wash and hand rub tests, and tests on inert
surface to establish that products have microbicidal activity against surface attached
micro-organisms. If the product passes, it qualifies for disinfectancy claims on surfaces.

Phase 3

Field test under practical conditions

Confirmatory test is expected to confirm the findings of Phaeses 1 and 2.
