20、ation, evaluates the ability of the materials used for passive fibre optic devices to withstand the action of fungi and bacteria and soil microorganisms likely to be encountered during usage. The type and extent of material deterioration may be determined by visual examination and/or changes in mass
21、 or any other physical property. Since mould growth conditions include high relative humidity, the test is applicable to passive optic devices under humid operating conditions according to IEC 61753-1, in storage and/or transport. 2 Normative references The following referenced documents are indispe
22、nsable for the application of this document. For dated references, only the edition cited applies.

24、document, the following abbreviations apply. ATCC: American Type Culture Collection (www.atcc.org) 4 General description This procedure is conducted in accordance with IEC 60068-2-10, test J. This test covers the inoculation of fibre optic products with a selection of mould spores followed by a peri
25、od of incubation under conditions which promote spore germination and the growth of mould.

Variant 1 sp
26、ecifies inoculation of the specimen with the mould spores without nutrients, whereas Variant 2 specifies the inoculation with the mould spores suspended in a nutritive solution which supports mould growth. For the environmental categories described in IEC 61753-1 Variant 1 shall be applied. The dete
27、rioration of the specimen may result in swelling that would destroy functional utility, cause loss of physical strength, and cause changes in other important mechanical properties. Therefore the following deterioration tests shall be done: a) visual examination; b) change of mass and dimensions; c)
28、changes in other physical properties, i.e. material strength characteristics. It is advisable to use testing procedures such as specified for plastics in ISO 846 to assess the vulnerability to damage by mould growth of the constructional materials used. 4.1 Health hazards to operators The mould grow
29、th test can constitute a health hazard, unless special precautions according to IEC 60068-2-10 are taken. 4.2 Microbial strains The fungi identified in Table 1 shall be used for performing the test and preparing the cultures.

For each test sample and method, 3 batches of specimens shall be prepared: c
33、ontrol specimen stored under standard atmospheric conditions according to IEC 61300-1; specimens inoculated and incubated; sterile specimens incubated as batch 2. For visual examination and mass and/or other physical changes determination, at least 3 specimens for each batch shall be prepared, i.e.
34、9 specimens each per sample and per test method. Do not clean and label the specimen. Labelling shall be done for example by use of containers. 5.3 Test Test specimens are exposed to test Variant 1 according to IEC 60068-2-10. At the end of the exposure the specimens are inspected before or after cl
35、eaning according to visual examination and/or changes in mass or other physical properties. The results are obtained by comparison of the specimens exposed to the biological attacks (batch 1) and those stored without contamination under standard (batch 2) and test (batch 3) environmental conditions.
36、 6 Severity The specimen shall be incubated at the chosen environmental conditions for 28 days, or longer by agreement between the customer and supplier. 7 Details to be specified The following details shall be specified: specimen configuration; all information needed for identification of the speci
37、men/product; the fungi, bacteria and soil used; the type of the microbicidal solution; the physical properties measured; the test methods used to measure physical properties; initial examinations and measurements and performance requirements; final examinations and measurements and performance requi
