ÖNORM EN 12662

This European Standard specifies a method for determining contamination as the content of undissolved substances in middle distillates, expressed as a mass fiaction in milligrams/kilogram. NOTE : Contaminants can give rise to faults, for example the blocking of filters, and their presence is therefore undesirable. This standard applies to liquid petroleum products having a kinematic viscosity not exceeding 8 mm2/s at 20 C, or 5 mm2/s at 40C, e.g. diesel fuel as specified in EN 590) or light fuel oils. The method described may also be used for petroleum products having a viscosity exceeding 8 mm2/s at 20C, or 5 mm2/s at 40C, although these need to be suitably diluted in order to obtain an acceptable filtration time. NOTE: For the purposes of this European Standard, the term "%(V/V)" is used to represent the volume fiaction. WARNING: The use of this standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the User of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
