  We tested sample of RME180 for Acid Number by ASTM D 664 and got result 1.05 mgKOH/g. As soon as Acid Number doesn't mentioned in the ISO 8217 spec. we have following questions:
  
  1. How can we interpret result 1.05 mgKOH/g obtained for RME180(for me it's looks untypically high)?
  
  2. How such acidity affects on conditions of main/aux. engines, and fuel treatment units? Is it critical or not?
  
  3. Which additional tests may be suggested in order to allocate possible source of contamination, i.e. organic/inorganic/industrial waste, etc.?
