Краски и лаки. Определение времени истечения с помощью воронки
Название (англ.):
Paints and varnishes; determination of flow time by use of flow cups
Описание (англ.):
Four flow cups of similar dimensions, but having orifice diameters of 3 mm, 4 mm, 5 mm and 6 mm, are specified, The method for their calibration is given. Flow time may be used to control consistency (a method for the adjustment of paints to the correct application consistency atthe application temperature is described in Annex A). The method is limited to testing materials for which the breakpoint of the flow from the orifice of the flow cup can be determined with certainty. This point is difficult to determine and reproduce for materials with flow times in excess of 100 s.
