ISO 846:2019

Plastics – Evaluation of the action of microorganisms

This standard specifies methods for determining the deterioration of plastics due to the action of fungi and bacteria and soil microorganisms. The tests are applicable to all plastics that have an even surface and that can thus be easily cleaned. The exceptions are porous materials, such as plastic foams.

Test Description

The test involves exposing test specimens of plastic to the action of selected test strains of fungi and bacteria (or, in the case of the soil-burial test, to microbially active soil) for specified or agreed periods of time under specified conditions of temperature and humidity.

  • Method A: Fungal-growth test.
  • Method B: Determination of fungistatic effects.
  • Method C: Resistance to bacteria.
  • Method D: Resistance to microbially active soil (soil-burial test).
