SCHEDULE II
(s. 12, 2nd par.)
ADDITIONAL REQUIREMENTS RELATING TO LOW TEMPERATURE FLOW PROPERTIES OF DIESEL FUELS
The cloud points of diesel fuels must comply with the maximum temperatures listed in Table I. According to the Table, the low temperature flow properties of diesel fuels are designed to give satisfactory performance at the temperatures indicated by the 2.5% low-end design temperature for a given period and location of intended use.
The design temperature is the lowest temperature at or below which 2.5% of the hourly outside temperatures were recorded for a given period.
The test method used to determine the operating temperature is that of the cloud point in ASTM International standard ASTM D2500 or ASTM D5773. For diesel fuels in which agents modifying the wax have been added to improve the flow properties, the test method used is the low temperature flow test for diesel fuels in Canadian General Standards Board standard CAN/CGSB-3.0 No. 140.1.
