Additional information

Liquid: The kinematic viscosity of the test item sodium polysulfide solution was determined according to OECD guideline no. 114 [adopted on 12 May 1981] with the capillary viscosimeter method. The determination of the kinematic viscosity was carried out by the capillary method with a viscosimeter according to Ubbelohde. For a specific liquid volume of the test item the flow time is measured through a capillary under the influence of gravity. The measurement is carried out at a specific temperature. The results are given in mm²s-1. The method is applicable to liquids with a kinematic viscosity between approx. 0.5 and 105 mm²s-1.

The kinematic viscosity of sodium polysulfide solution at 20 °C is 2.16 mm2 s-1
