Checking Fuel Quality

Information 

• Only carry out the analysis in well-ventilated rooms and at room temperature (20° Celsius).
• Before starting the analysis, have a good look at the information on the CD and read the leaflet (supplied in the case) carefully.
• This analysis can only determine a reference value; a laboratory test is required for an exact analysis.
• The analysis does not constitute a legal basis; it is the starting point for further steps.

5. Assign the scale value using the table below.

   Scale value (at 20° Celsius)	Assessment	Comment
   below 0	Case for fuel laboratory (neither petrol nor diesel)	Laboratory test required
   0... 5.5	Petrol EN 228
   4.5... 6.5	E 85
   approx. 7	E 100 (pure ethanol)
   7... 9	No evaluation possible (neither petrol nor diesel)	Laboratory test required
   9... 11	Diesel in Asia (Russia/India)
   10... 13	Diesel in accordance with EN 590 (Europe)
   13... 15	No evaluation possible, "wild mix"	Laboratory test required
   15... 17	Biodiesel	Laboratory test required
   above 17	Measuring spindle does not stay in the fuel (water-like density)	Laboratory test required

   Information 

   • Fuel, fuel mixes and cleaning mixes must be disposed of according to the applicable national regulations.
6. After testing the fuel, wash out and wash off measuring equipment thoroughly using the cleaning brush, washing-up liquid and hot water.
