documents provide greater information to users when confirming the performance of test chambers for either temperature or temperature/humidity testing. IEC 60721-2-7 Classification of environmental conditions. Environmental conditions appearing in nature. Fauna and flora. This document has been entirely re-written and now actually includes useful information on the detrimental effects of fauna and
flora. The advice provided relates to the potential occurrence of degradation, due to fauna and flora. BS EN IEC 60068-2-52 Environmental testing. Tests. Test Kb: Salt mist, cyclic (sodium chloride solution). This update to the salt mist test now mandates the composition of the sodium chloride to be used, specifically by setting limits on the impurities present.
