The minimum flow time should be 350 s for size no. 1 and 200 s for all other sizes.

Method. Fill the viscometer through tube (L) with a sufficient quantity of the liquid to be examined, previously brought to 20 °C unless otherwise prescribed, to fill bulb (A) but ensuring that the level of liquid in bulb (B) is below the exit to ventilation tube (M). Immerse the viscometer in the bath of water at 20 ± 0.1 °C, unless otherwise prescribed, maintain it in the upright position and allow to stand for not less than 30 min to allow the temperature to reach equilibrium. Close tube (M) and raise the level of the liquid in tube (N) up to a level about 8 mm above mark (E). Keep the liquid at this level by closing tube (N) and opening tube (M). Open tube (N) and measure, with a stop-watch to the nearest one-fifth of a second, the time required for the level of the liquid to drop from mark (E) to (F).
