testingthe selection and number of specimens and test pieces shall be as specified in 6.1.2 and 6.1.3 ofen 683-1 : 1996.tensile testing shall be carried out according toen 10002-1 noting the following: it applies to gauges between 80 mm and 350 mm; test pieces shall be either parallel sided (see figure 1) or with shoulders and a reduced parallel section.parallel sided test pieces shall be prepared using a double bladed cutter or guillotine (see figure 2) or a precision ground sample shear of punch and die construction.shouldered test pieces shall have a similar sampleshear or can be machined in packs using a milling-type cutter.parallel sided test pieces shall have a width of 15 mm 0,1 mm and a gauge length of50 mm 1 mm or 100 mm 1 mm.shouldered test pieces shall be in accordance with en 10002-1.during the part of the test to determine proof stress, the strain rate shall not exceed 10 mpa/s. the strainrate can then be increased until rupture but it shall not exceed 50 % of the gauge length per minute.considering the difficulty in marking thin gauge material, the gauge length may be measured by the distance between the grips of the testing machine. the elongation is then determined from the difference in the distance between the grips before testing and at fracture, or by direct reading from theload/crosshead-displacement diagram when available. this provision only applies to parallel-sided test pieces.4 mechanical propertiesmechanical property values for aluminium and aluminium alloys in finstock form are specified intable 1. for the elongation measurement, two different gauge lengths may be used. the choice of gauge length (either 50 mm or 100 mm) shall be at the discretion of the supplier unless otherwise agreed; nevertheless, the supplier shall inform the purchaser of the length used.5 rounding of test resultstest results shall be rounded in accordance with the rounding rules given in the annex a.lo gauge length = (50 1) mm or (100 1) mmwwidth = (15

one figure other than zero, the last figure to be retained is increased by 1.c) when the figure immediately after the last figure to be retained is equal to 5 and followed by zeros only, the last
