9、l 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 ISOtechnical committees. Each member body interested in a subject for which a technical committee has beenestab
10、lished 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 the InternationalElectrotechnical Commission (IEC) on all matters of electrotechnical standardizatio
11、n.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 Standardsadopted by the technical committees are circulated to the member bodies for voting. Pub
12、lication 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 subject of patentrights.

21、agreed between parties. Reduce thesample 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 suppliedinto another container of larger capacity and mixing thoroughly. It is important that any supernatant liquid n

Ensure that a representative sample of the wet mixture is obtained.7 Procedure7.1 Place four standard bricks, , with smooth surfaces and clean edges (removeany dust with a hard brush) in the drying oven and dry for at least , then cool to room temperature naturally.The bricks used in
23、 the test shall be compatible with the mortar to be tested.7.2 For dry mortars, place the mortar in the mixer and add water (or a specified mixing liquid) to the sampleand mix thoroughly to attain the desired consistency. Allow the mixed mortar to stand for or inaccordance with the manufacturers ins
24、tructions. Ready-mixed mortars shall be tested in the “as-received”state. Note the consistency in accordance with ISO 13765-1 or ISO 13765-2.7.3 Apply the well-mixed mortar to the face of the dried refractory brick. The longitudinalfaces of each brick shall be parallel to each other within a toleran
