The work of preparing International Standards is normally carried out through ISOtechnic
10、al committees. Each member body interested in a subject for which a technical committee has beenestablished has the right to be represented on that committee. International organizations, governmental andnon-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with
11、 the InternationalElectrotechnical Commission (IEC) on all matters of electrotechnical 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 Internati
12、onal Standardsadopted by the technical committees are circulated to the member bodies for voting. Publication as anInternational 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
13、 subject of patentrights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 13765-1 was prepared by Technical Committee ISO/TC 33, Refractories.ISO 13765 consists of the following parts, under the general title Refractory mortars: Part 1: Determination of consistenc

19、ts ready-to-use state4 PrincipleThe consistency of a refractory mortar is assessed by the depth of penetration of a specified cone into thesample.5 Apparatus5.1 Consistency determination device, consisting of a penetrometer, a cone and a container for the sample.The penetrometer is shown in Figure 1
20、. The requirements for the cone and the sample container are given in5.1.1 and 5.1.2.BS ISO 13765-1:200425.1.1 Cone.The cone shall be made of brass or corrosion-resistant steel with a smooth, polished surface. It shall be of thedimensions shown in Figure 2, and shall be machined such that the mass o

The gapbetween blade and bowl shown in Figure 3 shall be checked regularly depending on the frequency of use.NOTE The gap indicated in Figure 3 ( ) refers to the situation when the blade in the empty bowl is brought asclose as
27、possible to the wall.

Reduce thesample to by quartering or with a riffle sampler.Sample ready-
29、mixed mortars by emptying the entire contents of the container in which the mortar is suppliedinto another container of larger capacity and mixing thoroughly. It is important that any supernatant liquid not bediscarded. Ensure that a representative sample of the wet mixture is obtained.7 Procedure7.
30、1 For dry mortars, place the mortar in the mixer and add water (or the specified mixing liquid) in accordancewith the manufacturers instructions and mix thoroughly. Note the quantity of liquid added. Allow the mixedmortar to stand for , unless any specific instructions are given by the manufacturer,
31、 in which case theseshould be followed. Ready-mixed mortar shall be tested in “as received” state.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 surfac
32、e with a levelling rod and place it onthe test table.7.5 Adjust the position of the cone so that its tip is just in contact with the centre of the surface of the mortar inthe sample container. Lower the measuring gauge rod to contact the top of the drop rod and set the gauge tozero.7.6 Depress the s
33、tart (release) button and keep depressed for so that the cone can move freely. Releasethe button. Lower the toothed rod again to contact the top of the drop rod. Record the value on the measuringgauge scale to the nearest as the consistency of the mortar.7.7 Lift the toothed rod and cone. Clean the
34、cone. Repeat the operation described in 7.3 to 7.6.8CalculationCalculate the consistency as the mean value of the two tests to the nearest .In the case of dry mortars, calculate the percentage of the amount of water or mixing liquid added based on themass of the dry material.9 Test reportThe report
