EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN ISO 12937 testing. This International standard specifies a method for the direct determination of water in petroleum products boiling below 390°C. It covers the mass ratio range between 0,003% (m/m) and 0,100% (m/m). It does not apply to products containing ketones or residual fuels.
This international standard is applicable to the lubrication of base oils. However, precision has not been determined for these materials.
A number of substances and classes of compounds associated with condensation or oxidation-reduction reactions interfere with the determination of water by Karl Fischer titration.
The most common interventions in petroleum products are; Hydrogen sulfide and mercaptan sulfide, however, their mass fractions below 0,003% (m/m) as sulfur do not cause significant interference in the water range of 0,003% (m/m) to 0,100% (m/m) water.
Other commonly found organic sulfur compounds such as sulphides, disulfides, and thiophenes are immiscible. An alternative procedure is provided for the information in Annex B for the direct determination of water in the range of 0,003% (V/V) to 0,100% (V/V) in petroleum products.
