25、) IntroductionThe values of the properties obtained using test pieces are used to assess the homogeneity of monolithic (unshaped) materials. They are reference values which do not necessarily correspond with those obtained in industrial applications. Other methods of test-piece preparation or treatm

26、ent, which differ from those specified by this part of ISO 1927, can lead to different values.4DIN EN ISO 1927-5:2013-04 EN ISO 1927-5:2012 (E) 1 ScopeThis part of ISO 1927 specifies methods for the preparation and treatment (curing, drying and firing) of test pieces from monolithic (unshaped) refra

27、ctory materials. The methods are applicable to dense and insulating castables and to ramming materials with the four types of chemical composition defined in ISO 1927-1.The dimensions of the test pieces are specified and the preparation of the mixture, compaction methods, storage and post-treatment

28、of the test pieces are described.2 Normative referencesThe following referenced documents are indispensable for the application of this document.

31、 mm; thickness: 40 mm.The width of the test piece as tested shall correspond to the height during preparation. The vibration of the test piece during preparation shall be recorded, and for shapes C and D the compaction surface shall be marked for reference. The selection of test pieces for each type

32、 of material shall be as given in Table 1, except that for basic dense castables, ramming materials, taphole mixes and dry vibration mixes, test pieces with a diameter of 50 mm and height of 50 mm 1 mm are permissible and can be prepared using the sand-rammer.

A riffle sampler, suitable for use with the maximum p

35、article size of the product, or a shovel for the quartering method. The riffle separation shall be at least 2,5 times the maximum grain size.4.2 Mixer, comprising the following.4.2.1 Pan. The pan shall be symmetrical around axis A and shall have a capacity of 15 l to 30 l. Both the pan and the mixin

36、g blade (see 4.2.2) shall be constructed from a material that does not react with the test material (see Figure 1).6DIN EN ISO 1927-5:2013-04 EN ISO 1927-5:2012 (E) AB231Key1 Drive2 Pan3 Mixing bladeFigure 1 Principle of the mixer4.2.2 Mixing blade. The shape of the mixing blade shall be adapted to

37、the internal dimensions of the pan. The radius swept shall be such that the distance between the blade and the wall of the pan and the space between the blade and the bottom of the pan are at least as large as the maximum grain size of the material. For products with a maximum grain size of 6 mm or

38、less, the distance between the blade and the wall shall be 6 mm. For products with larger grain sizes (up to 25 mm), the blade is used in a manner such that the distance to the wall of the pan is 25 mm.The mixing blade shall revolve at a speed between 40 r/min and 65 r/min around axis A (the symmetr

39、y axis of the mixing pan), the blade rotating simultaneously in the opposite direction at a speed between 120 r/min and 145 r/min around axis B (symmetry axis of the blade).For low-intensity mechanical mixing of insulating castables the mixing blade shall revolve at a speed between 15 r/min and 25 r

40、/min around axis A (the symmetry axis of the mixing pan), the blade rotating simultaneously in the opposite direction at a speed between 50 r/min and 80 r/min around axis B (symmetry axis of the blade).4.3 Vibrating table. The vibrating table shall be flat and horizontal and shall perform only uniax

41、ial vertical vibrations at a frequency of 50 Hz. The table shall be capable of being set at a double amplitude of 0,50 mm (see ISO 1927-1) with an accuracy of 0,05 mm for the entire procedure. There shall be an automatic adjustment to the required double amplitude according to the mass of the mould

42、and material.7DIN EN ISO 1927-5:2013-04 EN ISO 1927-5:2012 (E) 4.4 Pneumatic rammer. A compressed-air rammer shall have a rammer foot suitable for the width of the mould and have a smooth, flat working surface, i.e. 52 mm 25 mm for shape B and 62 mm 25 mm for shape C.The mass of the rammer and the f

43、requency of ramming shall be chosen in order to obtain a prescribed green bulk density, which shall be reported in the test report.4.5 Sand-rammer, consisting of a mould of 50 mm inside diameter, and 140 mm in length, and a 6,67 kg 50 g weight sliding on the shaft of the apparatus and arranged to fa

44、ll a distance of 50 mm before engaging a collar attached to the shaft. At the lower end of the shaft there is a plunger, the diameter of which is about 0,3 mm smaller than the inside diameter of the mould (see Figures 2 and 3).NOTE A more detailed description of this piece of apparatus is given in I

The press sha

46、ll be capable of applying a minimum of 10 MPa pressure to the moulded face.NOTE The power press should only be used for shaping test pieces from plastics.4.7 Trowel, pointing type or stiff-bladed spatula of typical size 150 mm length and 50 mm width.4.8 Watertight moulds, capable of being dismantled

47、 and shall be watertight. They shall be made from a material that does not react with the material to be tested.For compaction by the pneumatic rammer, the moulds shall be rigid so that they do not warp during ramming.NOTE 1 Steel or similar material is recommended to withstand the stroke of the ram

48、mer.The internal measurements of the moulds are determined by the dimensions of the test pieces. The surfaces 230 mm 64 mm (shapes A and C) and 230 mm 54 mm (shape B) are the horizontal surfaces during the compaction process. A variation of 0,5 mm is allowed for these dimensions. If multi-compartment moulds are used, the size of the mould shall be adapted for the number of test pieces prepared and this shall be indicated in the test report.In order to overfill the mould,
