BS EN 1094-1:2008EN 1094-1:2008 (E) 4 1 Scope This
16、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 HTIW and specifies methods for determining the thickness, bulk density, resili
17、ence, 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 products delivered in a wet state. Further test procedures are in development and
18、 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 methods) and thermal conductivity measurement. There is a shot content method de
19、scribed 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. For dated references, only the edition cited applies. For undated references, the latest editio

21、tem (ISO 7500-1:2004) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 General terms and definitions 3.1.1 high temperature insulation wool HTIW man-made mineral wool suitable for use as heat-insulating materials above a temperature of 600C an
22、d divided into amorphous alkaline earth silicate wools (AES), aluminosilicate wools (ASW) and the polycrystalline wools (PCW) with a classification temperature greater than 1 000 C 3.1.2 wool non-directional agglomeration of fibres with varying diameter and length distributions 3.1.3 fibre particles

24、220Other oxides 1250 C from ambient temperature up to 1200 C between 5 and 10 C/min from 1200 C to 50 C below the test temperature between 2 and 5 C/min for the last 50 C between 1 and 2 C/ min 7.4.4.3 Measurement of the test pieces after the test Allow test pieces to cool in the furnace until it is
25、 practical to remove them without damage and then allow them to cool further to room temperature, then measure the distances between markers as previously. BS EN 1094-1:2008EN 1094-1:2008 (E) 17 7.4.5 Calculation and expression of the results For each test piece, calculate the permanent linear chang
26、e 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 recorded for each direction on each of the three test pieces. 7.4.6 Test report Prepare a te
27、st 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 strength 7.5.1 Principle A test piece of prescribed dimensions is cut from the product
28、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 the test piece over a 75 mm x 40 mm area. This device shall be capable of straining the
29、 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 possible, take test pieces at random along the longitudinal axis of the product. It is pref
30、erable 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 perpendicular to the manufacturing direction. Dry test pieces at (110 5) C, then cool the
31、m 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 dial gauge comparator method and the width using a ruler accurate to 1 mm. Clamp the test
32、 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 constant speed of 100 mm/min during the whole test. Apply the stress parallel with the manuf
33、acturing 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, use the maximum load recorded in the course of a test resulting in the parting of the te
34、st piece. BS EN 1094-1:2008EN 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, in N; W is the width of the active part of the test piece, in m; t is the measured thickness
35、 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. 7.5.6 Test report Prepare a test report in accordance with Clause 8, including the direction
36、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 matter content 7.6.1 General Because of its relatively high surface area, HTIWs are suscepti
37、ble 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 manufactured with HTIWs and it is often necessary to measure the content of these binders. 7.6.2 Pri
38、nciple 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 nearest 0,001 g. 7.6.3.2 Silica dish, or other suitable container. 7.6.3.3 Ventilated oven, cap
39、able 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. BS EN 1094-1:2008EN 1094-1:2008 (E) 19 7.6.4 Procedure 7.6.4.1 Moisture content Use three test pieces. Weigh not less than 10 g of the sample to 0,001 g, (M1) and place in a tared
40、 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 in a muffle furnace at (650 10) C for not less than 1 hour. Furnace should be at temperature and
41、 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 Calculation and expression of result Calculate the moisture content (Mm), expressed as a percentage o
42、f 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 (Mo), expressed as a percentage of the dry sample mass, using the following equation: 100xMMMM232o
43、= 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 results and their mean. BS EN 1094-1:2008EN 1094-1:2008 (E) 20 8 Test report The test reports shall c
