These will be changed to SSA numbers when they are given final approval by SASO.</p><p> 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.</p><p> 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.</p><p> d) This method is applicable to low sulfur content ( less than 0.4% by Weight )</p><p> 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 %.</p><p> 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.</p>
