28、ation and 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
29、 recorded 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 te
30、nsile strength 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 clampi
31、ng of the 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 a
32、s possible, 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 ta
33、ken perpendicular 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
34、the dial 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
35、 constant 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 resu
36、lts, use the maximum load recorded in the course of a test resulting in the parting of the test piece.

37、he 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 of the test piece, in m, as measured in subclause 7.1. Express the test result as the mean of those determi
38、nations 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 of taking out test pieces, the type of tensile testing machine, the bulk density of the product, and the mea
39、n 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 susceptible to moisture pick-up after manufacture and especially during storage. Often it is necessary to know if th
40、e 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 Principle Moisture and organic contents are measured by weight loss of the sample at temperatures suitable to r
41、emove 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, capable of maintaining (110 5) C. 7.6.3.4 Desiccator. 7.6.3.5 Muffle furnace, capable of heating test pieces to
42、 (650 10) C.

Weigh not less than 10 g of the sample to 0,001 g, (M1) and place in a tared dry dish
43、. 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 sample s
44、hould 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 of the ori
45、ginal 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= where M
46、2is 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.
