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 fuel must permit satisfactory performance at 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 the American Society for Testing and Materials standard ASTM D 2500 or ASTM D 5773. 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 (LTFT) for diesel fuels in Canadian General Standards Board standard CAN/CGSB-3.0 No. 140.1.

Notes:
1 Seasonal cloud points conforming to low-end design temperatures from CGSB 31 October 2001 data.
2 Use zones correspond to the zones in Figure I.
3 Cloud points differing as to storage and use conditions may be specified in a written agreement between the user and the supplier.
