Specifies the methods for determining the deterioration of plastiques due to the action of fungi and bacteria and soil microorganisms. The aim is not determine the biodegradability of plastics. The type and extent of deterioration may be determined by: a) visual examination and/or b) changes in mass and/or c) determination of the changes of other physical properties of the plastics. These tests are applicable to all articles made of plastics that have an even surface and that can thus be easily cleaned. The exceptions are porous materials, such as plastic foams. For plastics to be used in electronic components or equipment the option exists to use the funghi specified in IEC 68-2-10. The method followed and the test strains to be used will depend on the envisaged application of the plastics. These parameters should therefore be agreed upon before the tests are started and should be stated in the test report.
