It is not necessary to use all the methods to characterize a material.4 Determination of permeability to gases4.1 PrincipleThis de
36、termination shall be carried out on test pieces after drying or after firing at a temperature and time to be agreed between the parties involved.4.2 Test piecesUse cylindrical test pieces with dimensions as defined in ISO 8841 and obtained from shapes A, B or C by sawing or coring, and prepared, sto
37、red, dried and/or fired according to the relevant sections of ISO 1927-5. The direction from which the test pieces are cut with regard to the direction of shaping shall be stated in the test report; the plane faces of the cylinder shall be at least at 4 mm away from the initial faces of the shape.If
38、 the test pieces cannot be obtained by sawing or coring, due to the nature of the material, they may be prepared directly and this shall be noted in the test report.In all cases, the test pieces shall be dried at 110 C 5 C for a minimum of 24 h and fired at a temperature and time to be defined betwe
39、en the parties and noted in the test report.4.3 ProcedureDetermine the permeability to gases in accordance with ISO 8841.5 Determination of the resistance to thermal shock5.1 PrincipleThis determination shall be carried out on test pieces fired at a temperature equal to or higher than the temperatur
40、e of the test.The standard quenching temperature shall be 950 C and prefiring of the test pieces shall be carried out at 950 C or above for 5 h.Other quenching and prefiring temperatures and times may be agreed upon by the parties concerned and shall be noted in the test report.5.2 Test piecesTest p
41、ieces with dimensions of shape B, i.e. 230 mm 64 mm 54 mm shall be used. They shall be prepared and prefired according to ISO 1927-5 at a temperature and time agreed between the involved parties (see 5.1).NOTE The use of other shapes may be agreed by the parties, but the results are not comparable w
42、ith those using the test pieces stated above.5.3 ProcedureDetermine the resistance to thermal shock of the prefired test pieces in accordance with method B of EN 993-11:2007.5DIN EN ISO 1927-8:2013-04 EN ISO 1927-8:2012 (E) 6 Determination of thermal conductivity6.1 PrincipleThis determination may b
43、e carried out on fired or unfired, dried test pieces in accordance with ISO 8894-1 (hot wire, cross array) or with ISO 8894-2 (hot wire, parallel).For both fired and unfired, dried test pieces, variation in thermal conductivity can occur due to time-dependent mineralogical and microstructural change
44、s if the test piece has not been prefired to a temperature equal to or higher than the measurement temperature.It is therefore necessary to take special care to ensure that equilibrium is attained when testing such test pieces. This can entail holding the test furnace at the measurement temperature
45、for prolonged periods.6.2 Test piecesTest pieces shall be used corresponding to shape A as defined in ISO 1927-5.For fired test pieces, the firing shall be carried out in accordance with ISO 1927-5 or as agreed between the parties.6.3 ProcedureDetermine the thermal conductivity at each defined measu
46、rement temperature in accordance with ISO 8894-1 (hot wire, cross array) or ISO 8894-2 (hot wire, parallel). For unfired test pieces, the rate of rise of the test furnace shall be in accordance with that specified in ISO 1927-5 for the type of material under test.In all cases where the test piece ha
47、s been prefired, (either before or during the test) to a lower temperature than the measurement temperature, it may be necessary to maintain the furnace at this temperature for extended periods to attain equilibrium. In some cases, it is advisable to maintain the temperature overnight.7 Determinatio
48、n of sulfuric acid resistance7.1 PrincipleDetermination of sulfuric acid resistance consists of the chemical attack by sulfuric acid on test pieces crushed to a specific grain size.7.2 Test piecesUse shape A test pieces prepared in accordance with ISO 1927-5, stored and dried at 110 C 5 C for a minimum of 24 h. Samples shall be taken out from test pieces in accordance with ISO 8890.Any pre-treatment of the test pieces shall be agreed between the
