DIN EN 1094-1:2008-09 EN 1094-1:2008 (E) 4 1 Scope This European Standard defines terms for those refractory products and materials which are classed as high temperature insulation wools (HTIW). It also establishes the classification of insulating refractory products made from HT
22、IW and specifies methods for determining the thickness, bulk density, resilience, permanent linear change, tensile strength and moisture and organic matter content of HTIW products. It applies to HTIW bulk wool, blankets, felts, mats, boards, pre-formed shapes and papers, with the exception of produ
23、cts delivered in a wet state. Further test procedures are in development and will be included once they have been ratified. These include a 3 point bend test for boards, a length weighted fibre diameter measurement technique by Scanning Electron Microscope, shot content measurement (dry and wet meth
24、ods) and thermal conductivity measurement. There is a shot content method described in ISO 10635 and there is a thermal conductivity technique described in ASTM C201. 2 Normative references The following referenced documents are indispensable for the application of this document.

30、e test pieces after the test Allow test pieces to cool in the furnace until it is practical to remove them without damage and then allow them to cool further to room temperature, then measure the distances between markers as previously. DIN EN 1094-1:2008-09 EN 1094-1:2008 (E) 17 7.4.5 Calculation a
31、nd expression of the results For each test piece, calculate the permanent linear change as the mean of two values measured in two different directions, expressed as a percentage of the initial length measured between the platinum wire markers. Express the test result as the mean of the values record
32、ed for each direction on each of the three test pieces. 7.4.6 Test report Prepare a test report in accordance with clause 8, including the bulk density, the measuring device, the heating rate, with the test result in each direction and the mean for each test piece. 7.5 Determination of the tensile s
33、trength 7.5.1 Principle A test piece of prescribed dimensions is cut from the product or the item, and the tensile strength determined by causing rupture of the test piece at room temperature. 7.5.2 Apparatus 7.5.2.1 Tensile testing machine, provided with two pairs of jaws allowing the clamping of t
34、he test piece over a 75 mm x 40 mm area. This device shall be capable of straining the test piece in tension at a constant cross head speed and shall be Class 2 as defined by EN ISO 7500-1. 7.5.3 Test pieces Cut at least five test pieces (230 5) mm x (75 2) mm x (measured thickness). As far as possi
35、ble, take test pieces at random along the longitudinal axis of the product. It is preferable that the longest dimension of the test piece (230 mm) is parallel with the manufacturing direction of the product. NOTE By agreement between parties, and for supplementary tests, test pieces can be taken per
36、pendicular to the manufacturing direction. Dry test pieces at (110 5) C, then cool them to room temperature in a desiccator and carry out testing immediately on removal. 7.5.4 Procedure Measure the thickness of the test piece in the area to be strained in accordance with subclause 7.1, using the dia
37、l gauge comparator method and the width using a ruler accurate to 1 mm. Clamp the test piece at both ends so that a surface area of approximately (75 x 40) mm is held in the jaws of the testing machine. The rate of the tensile stress shall be variable so that the piece deformation occurs at a consta
38、nt speed of 100 mm/min during the whole test. Apply the stress parallel with the manufacturing direction of the product. In the calculation, reject values from tests where parting occurred closer to the jaws than to the centre. In this case, cut new test pieces For the calculation of the results, us
39、e the maximum load recorded in the course of a test resulting in the parting of the test piece. DIN EN 1094-1:2008-09 EN 1094-1:2008 (E) 18 7.5.5 Calculation and expression of the results Calculate the tensile strength, R(m), in Pa, using the equation ()tWFmR= where F is the maximum parting force, i
40、n N; W is the width of the active part of the test piece, in m; t is the measured thickness of the test piece, in m, as measured in subclause 7.1. Express the test result as the mean of those determinations together with the bulk density of the product determined in accordance with subclause 7.2. 7.
41、5.6 Test report Prepare a test report in accordance with Clause 8, including the direction of taking out test pieces, the type of tensile testing machine, the bulk density of the product, and the mean of five determinations carried out on five test pieces. 7.6 Determination of moisture and organic m
42、atter content 7.6.1 General Because of its relatively high surface area, HTIWs are susceptible to moisture pick-up after manufacture and especially during storage. Often it is necessary to know if the product has adsorbed water. Additionally organic binders are used in many of the articles manufactu
43、red with HTIWs and it is often necessary to measure the content of these binders. 7.6.2 Principle Moisture and organic contents are measured by weight loss of the sample at temperatures suitable to remove the water or organic material. 7.6.3 Apparatus 7.6.3.1 Balance, capable of weighing to the near
44、est 0,001 g. 7.6.3.2 Silica dish, or other suitable container. 7.6.3.3 Ventilated oven, capable of maintaining (110 5) C. 7.6.3.4 Desiccator. 7.6.3.5 Muffle furnace, capable of heating test pieces to (650 10) C. DIN EN 1094-1:2008-09 EN 1094-1:2008 (E) 19 7.6.4 Procedure 7.6.4.1 Moisture content Use
45、 three test pieces. Weigh not less than 10 g of the sample to 0,001 g, (M1) and place in a tared dry dish. Dry in the ventilated oven for not less than 1 hour, cool in the desiccator and reweigh (M2). 7.6.4.2 Organic content Dry sample as described above to obtain dried weight (M2). Heat the sample
46、in a muffle furnace at (650 10) C for not less than 1 hour. Furnace should be at temperature and sample should be removed from furnace whilst still at 650C. Initially cool, for example on a heat-resisting mat, and when sufficiently cool, transfer to a desiccator. When cool, reweigh (M3). 7.6.5 Calcu
47、lation and expression of result Calculate the moisture content (Mm), expressed as a percentage of the original sample mass, using the equation: 100xMMMM121m= where M1is the initial mass of the sample, in g; M2is the mass of the sample after drying, in g. Calculate the total organic matter content (M
48、o), expressed as a percentage of the dry sample mass, using the following equation: 100xMMMM232o= where M2is the mass of the sample after drying, in g; M3is the mass of the sample after heating, in g. 7.6.6 Test report Prepare a test report in accordance with Clause 8, including the individual resul
49、ts and their mean.
