Compared with the previous edition, EN 12846:2002, the scope and principle were detailed, Figure 2 was added, tolerances were specified or modified in the apparatus dimensions, details were added in the test procedure and measurements made and the test precision data were reviewed. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

Three forms are required, differing only in the size of the orifice (10 mm, 4 mm and 2 mm). For other dimensions of the cup and the ball-valve, see Figure 3. The cup cylinder shall be made of brass. The ball valve should be made of corrosion-resistant metal, with a ball on a rod, a levelling peg attached to the rod and a hemispherical top by means of which the valve may be supported in a vertical position. The viscometer cups shall be equipped with suitable corks or caps for closing the orifices with the ball valve in position, and some means of covering the cups (e.g. lids) to prevent evaporation of water and minimize surface cooling effects. The viscometer-cup holder shall be capable of:  supporting one or more cups in a vertical position;  providing a valve support to hold the valve at least 16 mm vertically above the orifice of the cup during efflux of the test material. NOTE 1 To enhance resistance to wear and corrosion of the ball and socket valve, the bottom of the cup may be made from a different, corrosion resistant, material and screwed to the brass tube. It is then advised to use the same material, such as for instance phosphor-bronze, for the cup bottom and the ball valve. Wrought nickel alloy with copper or metals NiCu30 in accordance with ISO 9722 are possible materials for the rod of the ball valve. SIST EN 12846-1:2011

6.4 Thermometers, two, conforming to the requirements described in Annex A. Other temperature measuring devices may be used instead of mercury stem thermometers. However, the mercury stem thermometer is the reference device. Therefore any alternative device employed shall be calibrated so as to provide the same readings as would be provided by the mercury stem thermometer, recognising and allowing for the fact of changed thermal response times compared with the mercury thermometer.
