Notes:

a) The PS-Test methods are proposed SASO methods. These will be changed to SSA numbers when they are given final approval by SASO.

b) Targets for Cold Flow Properties are based on Analysis of Diesel Cold Flow Properties: Specification Target Setting, P&CSD/PED-L197/95, April 11, 1995.

c) The 10 C (18 F) maximum margin specification applies only when the CFPP is being used as the primary method in conjunction with the injection of cloud point supressant chemicals. The 10 C (18 F) maximum margin specification is calculated between the CFPP spec and the actual cloud point test.

d) This method is applicable to low sulfur content ( less than 0.4% by Weight )

e) Saudi Aramco guarantees only two significant figures ( 1.0 wt % ) for sulfur. The third figure (1.0X % ) will be rounded off to the nearest number. For example, reported Sulfur results of 1.04 wt % and 1.05 wt % will be considered as ON-SPEC and OFF-SPEC, respectively since 1.04 wt % will be rounded off to 1.0 wt % 1.05 wt % will be rounded off to 1.1 wt %.

f) The rounding off technique is applicable to all Saudi Aramco Product Specifications to the nearest significant figure, similar to the example in note e.
