Duration and Unusual Extremes of Cold. Supplement I
Abstract
The study supplements 'Duration and Unusual Extremes of Cold, AD-710 611 dated 26 June 1970. It presents revised values of low-temperature extremes that correspond to recently modified guidance on acceptable risk. A low temperature of -50 degrees F corresponds to the value that equipment will encounter with a 50 percent probability when it is exposed in small record-making cold basins of Siberia during the coldest month. The 50 percent probability level is now applicable to operation of equipment. Associated with this extreme is a 1-month cycle of temperatures that are characteristic of the complete thermal regime in which a minimum of -50 degrees F is imbedded. When not in operation, equipment must be able to withstand temperatures in the -81 to -88 degree F range for 1 hour, and below -29 degrees F for 32 days.
