# Commission Regulation (EU) No 284/2013 of 1 March 2013 setting out the data requirements for plant protection products, in accordance with Regulation (EC) No 1107/2009 of the European Parliament and of the Council concerning the placing of plant protection products on the market (Text with EEA relevance), Division 2.5: Viscosity and surface tension

Extent: E+W+S+N.I.

For liquid formulations the viscosity shall be determined at two shear rates and at 20°C and 40°C and reported together with the test conditions. The surface tension shall be determined at the highest concentration.
For liquid plant protection products containing ≥10 % hydrocarbons and for which the kinematic viscosity is less than 7 × 10– 6 m2/sec at 40 °C the surface tension of the neat formulation shall be determined at 25 °C and reported.
