'''operability temperature'''<br>
lowest temperature at which the fuel oil is designed to provide satisfactory performance under the conditions of storage and use (see 6.23, 6.24 and 9.2).The 2.5 percentile low-end design temperature is the temperature at or below which 2.5% of the hourly outside air temperatures are observed to occur for an indicated half month. The 2.5% low-end design temperature for most weather stations in Canada by half month period is available on the Canadian Fuels Association Web site (see 2.2). This data is based upon a statistical analysis of hourly weather readings from weather stations across Canada over the thirty year period from 1981 to 2010 inclusive.
