EN 1159-1:2003 (E)54 Principle4.1 GeneralA test piece is heated and subsequently cooled, either at a specified uniform rate or using defined temperatureincrements. Its change of length and its temperature are measured continuously or at regular frequent intervalsduring the imposed temperature cycle.One of two methods may be used to determine the linear thermal expansion coefficient, either by directmeasurement or by a differential method.4.2 Direct measurementIn this method the variation in length of the test piece is measured directly. It is necessary to know the change indimensions of the test piece support system by previous calibration.The test piece is placed in a specimen holder and is made to contact a displacement transducer by using a pushrod made of the same material as the holder. This assembly is put in a furnace. The differential expansion betweenthe test piece and the test piece holder is measured during the increase and the decrease in temperature.The apparatus is shown in Figure 1.4.3 Differential methodThis method consists of measuring the changes in length between a reference piece (see 6.2) and the test piece.Its is not therefore necessary to know the change in dimensions of the test piece support system.The apparatus is shown in Figure 2.5 Apparatus5.1 Construction materialsThe test piece holder and the push rod shall be made from thermomechanically stable materials of the same type,which shall be chemically inert and thermally compatible with the test piece material under the environmentalconditions of the test.NOTEFor temperatures above 1 400 °C, it is necessary to employ a vacuum or inert gas atmosphere, with a non-oxidematerial appropriate for the test environment, such as a grade of dense graphite.5.2 Heating and cooling deviceFurnace, capable of working in a controlled atmosphere when required, and of contro
