Middle distillate, diesel and fatty acid methyl esters
Determination of total pollutant content
Caution - Personnel using this standard should have practical experience in formal laboratory work. The use of this standard may involve certain hazards
Hazardous materials, equipment and operations, this standard does not indicate all possible safety issues. It is the user's responsibility to take appropriate safety and health measures
And to ensure compliance with the provisions of the relevant national laws and regulations.
1 Scope
This standard specifies the total distillate oil, fatty acid methyl ester volume fraction of not more than 30% of diesel and pure fatty acid methyl ester (BD100) in the total
Determination of pollutant content.
This standard applies to 20 ℃ kinematic viscosity of not more than 8mm2/s, or 40 ℃ kinematic viscosity of not more than 5mm2/s samples, such as wood
Oil and pure fatty acid methyl ester (BD100). This standard applies to samples with a total contaminant content of 12 mg/kg to 30 mg/kg and provides for
Precision; also applies to the total pollutant content beyond the scope of the sample, but its precision is not specified. This standard can also be used to determine fatty acids
Methyl ester volume fraction greater than 30% diesel and kinematic viscosity beyond the scope of the product, but the precision of the method is not determined.
Note 1. Excessive contaminants in the fuel system can cause filter blockage and/or hardware failure and therefore do not meet the needs of the user.
Note 2. This standard in the determination of pure fatty acid methyl ester in the total contaminant content of the measured results and the relevant standards there is a big difference, see Appendix A.
