10、, Uncontrolled Copy, (c) BSI iii Foreword ISO (the 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 inte
11、rested in a subject for which a technical committee 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 Electrotechnica
12、l 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 International Standards adopted by the t
13、echnical committees are circulated to the member 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. I
14、SO 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 consistency using the penetrating c

19、es of this document, the following terms and definitions apply. 3.1 refractory mortar finely ground refractory composition which, generally after the addition of water or other specified mixed liquid, is used for laying and jointing bricks NOTE 1The refractory components are related to the quality o
20、f the bricks with which the composition is to be used. NOTE 2In 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 its ready-to-use state 4Principle The consistency of a refractory mortar is assessed by the
21、depth of penetration of a specified cone into the sample. 5Apparatus 5.1Consistency determination device, consisting of a penetrometer, a cone and a container for the sample. The penetrometer is shown in Figure 1. The requirements for the cone and the sample container are given in 5.1.1 and 5.1.2. B

28、 is driven in a planetary movement around the axis of the bowl by an electric motor at controlled rotational frequencies. 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

32、ed between parties. Reduce the sample to by quartering or with a riffle sampler. Sample ready-mixed mortars by emptying the entire contents of the container in which the mortar is supplied into another container of larger capacity and mixing thoroughly. It is important that any supernatant liquid no
33、t be discarded. Ensure that a representative sample of the wet mixture is obtained. 7Procedure 7.1For dry mortars, place the mortar in the mixer and add water (or the specified mixing liquid) in accordance with the manufacturers instructions and mix thoroughly. Note the quantity of liquid added. All
34、ow 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” state. 7.2Measure the temperature of the mixed mortar to the nearest . 7.3Set the penetrometer vertically and
35、 attach a clean dry cone. 7.4Fill the sample container with the well-mixed mortar, level the surface with a levelling rod and place it on the test table. 7.5Adjust the position of the cone so that its tip is just in contact with the centre of the surface of the mortar in the sample container. Lower
36、the measuring gauge rod to contact the top of the drop rod and set the gauge to zero. 7.6Depress the start (release) button and keep depressed for so that the cone can move freely. Release the button. Lower the toothed rod again to contact the top of the drop rod. Record the value on the measuring g
37、auge scale to the nearest as the consistency of the mortar. 7.7Lift the toothed rod and cone. Clean the cone. Repeat the operation described in 7.3 to 7.6. 8Calculation Calculate the consistency as the mean value of the two tests to the nearest . In the case of dry mortars, calculate the percentage
38、of the amount of water or mixing liquid added based on the mass of the dry material. 9Test report The report shall include the following information: a)all information necessary for identification of the material tested, including a description of the material, manufacturer, type, brand, batch numbe
