A Review of Land Surface Temperature and Humidity Conditions Specified for Australia in DEF (AUST) 5168 and STANAG 2895

Australian Ordnance Council AOC Task 154 Definition of the Australian Environmental Conditions Affecting the Design of Military Materiel was accepted by the Explosives Environmental and Service Life Advisory Committee EESLAC in 1990 to provide a concise definition of the possible manufacture to target environments to which materiel designed for the ADF could be exposed. This task was divided into two discrete areas of work by EESLAC, namely a study of surface transport vibration levels and a comparative analysis of available meteorological data and the contents of DEF AUST 5168. This paper discusses the latter analysis, expanded to include a review of STANAG 2895 also. In general, the available data suggests that the operational and storage diurnal cycles defined in the two standards reasonably represent the conditions likely to be experienced in Australia. However, the effects of direct solar radiation on materiel must also be considered in determining the maximum temperature which the materiel surface is likely to attain.
