7、e International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committ
8、ee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechn
9、ical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member
10、bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying

NOTE 2 In some cases the mortar may be supplied in a ready-mixed state. 3.2 consistency of refractory mortars measure of the viscosity of the material in
17、its ready-to-use state 4 Principle The consistency of a refractory mortar is assessed by the depth of penetration of a specified cone into the sample. 5 Apparatus 5.1 Consistency determination device, consisting of a penetrometer, a cone and a container for the sample. The penetrometer is shown in F

23、the gap between blade and bowl can be finely adjusted and fixed; 5.2.2 Metal blade, of the general shape, size and tolerances shown in Figure 3, rotating about its own axis as it is driven in a planetary movement around the axis of the bowl by an electric motor at controlled rotational frequencies.
24、The two directions of rotation shall be opposite and the ratio between the two frequencies shall not be a whole number. Where more than one mixer is used, blades and bowls shall form sets which are always used together. The gap between blade and bowl shown in Figure 3 shall be checked regularly depe

Sample ready-mixed mortars by emptying the entire contents of the container in which the mortar is supplied into
28、another container of larger capacity and mixing thoroughly. It is important that any supernatant liquid not be discarded. Ensure that a representative sample of the wet mixture is obtained. 7 Procedure 7.1 For dry mortars, place the mortar in the mixer and add water (or the specified mixing liquid)
29、in accordance with the manufacturers instructions and mix thoroughly. Note the quantity of liquid added. Allow the mixed mortar to stand for , unless any specific instructions are given by the manufacturer, in which case these should be followed. Ready-mixed mortar shall be tested in “as received” s
30、tate. 7.2 Measure the temperature of the mixed mortar to the nearest . 7.3 Set the penetrometer vertically and attach a clean dry cone. 7.4 Fill the sample container with the well-mixed mortar, level the surface with a levelling rod and place it on the test table. 7.5 Adjust the position of the cone
31、 so that its tip is just in contact with the centre of the surface of the mortar in the sample container. Lower the measuring gauge rod to contact the top of the drop rod and set the gauge to zero. 7.6 Depress the start (release) button and keep depressed for so that the cone can move freely. Releas
32、e the button. Lower the toothed rod again to contact the top of the drop rod. Record the value on the measuring gauge scale to the nearest as the consistency of the mortar. 7.7 Lift the toothed rod and cone. Clean the cone. Repeat the operation described in 7.3 to 7.6. 8C a l c u l a t i o n Calcula
