3、70/26882 ISBN 580 06849 8 Foreword This British Standard is part of a composite standard in the Aerospace Series of British Standards specifying general requirements for equipment in aircraft. An introduction to the complete standard is given in BS 3G.100-O, Introduction. This subsection of BS 3G.10
4、0 supersedes Clause 208 c), “Tests for resistance to fungus growth”, in BS 2G.100-2. It details a short exposure test (28days) to assess the extent of mould growth, and a long exposure test (84days) to assess the effect of mould growth on the performance of aerospace equipment, materials and compone
5、nts in aircraft. It does not relate to mycological tests on such hydrocarbons as aircraft fuels, oil etc., which should be tested in a manner agreed between the appropriate authorities. This standard makes reference to the following: BS 2011, Basic environmental testing procedures. BS 2011-2.1J, Tes

It should also be read in conjunction with BS 3G.100-O. 2 Tests and test methods Tests for mould growth shall be generally conducted in accordance with the requirements specified in BS2011-2.1J “Test J. Mould growth” and of th
11、e relevant equipment specification. 2.1 The28day short exposure test shall be the normal test to be specified. 2.2 The 84 day long exposure test shall only be applied in special cases and when specifically required by the relevant equipment specification. 2.3 The tests may only be applied to complet
