What is BS EN 61197 - Insulation liquids about?      
BS EN 61197 is a British Standard for insulation liquids.
BS EN 61197 guideline specifies a method for measurement of linear flame propagation along a glass-fibre tape impregnated with the insulating liquid to be tested.
BS EN 61197 is applicable to all insulating liquids, used and unused, with kinematic viscosity lower than or equal to 300 mm2/s at 40 °C. Insulating liquids of higher viscosity may also be tested but should be heated before impregnation of the glass-fibre tape.
