NOTE When a long gauge length and large elongation are applied, the maximum relative error of the class 1 extensonieter may be greater than ± 0,01 mm.
The method of gripping the test piece shal be as specified in Iso 6892.
7 Test piece
7.1 The test piece shall be taken in accordance with the requirements of the relevant product standard or, if not specified therein, as agreed between the interested parties.
The type of the test piece and its preparation, including machining tolerances, the tolerances on shape and the marking of the original gauge length, shall be as defined in ISO 6892:1998, Annex A, but within the gauge length the edges shall be sufficiently parallel that two width measurements do not differ by more than 0,1 % of the mean of all the width measurements.
7.2 The test piece thickness shall be the full sheet thickness, unless otherwise specified.
7.3 The surface of the test piece shall not be damaged. e.g. by scratches.
8 Procedure
8.1 In general, tests are carried out at ambient temperature between 10 °C and 35 C. Tests carried out under controlled conditions, where required, shall be made at a temperature of (23 ± 5) °C.
8.2 If the measurements are made manually, the original width of the test piece shall be measured at a mInimum of three points evenly distributed along the gauge length. lnefuding one measurement at each end of the gauge length. The mean value of these width measurements shall be used In calculating the plastic strain ratio,
8.3 If the measurements are made automatically, the extension and the change of width, at least at one measurement point, shall be measured using an extensometer. as specified In Clause 6.
The method of gripping the test piece shal be as specified in Iso 6892.
