4.3.2.2 Tensile test
The tensile test shall be carried out in accordance with EN 10002-1 on test pieces with a reduced section 12,5 mm wide taken parallel with the rolling direction (longitudinal direction). The elongation shall be rneaswed on an original gauge length 0(50 mm. Mechanical properties after simulated lacquer stoving shall be determined after heat treating the test pieces at 205 C for 20 men en a laboratory furnace.
For determination of compliance. Deld strength and tensile strength values shall be rounded to the nearest 1 MPa and elongation values to the nearest 0.1 % using the rounding rules given In Annex B.
4.3.2.3 Measurement of dimensions
The dimensions shall be measured by measuring Instruments that are accurate to 1/5 of the relevant tolerance.
All dimensions shall be checked at the ambient temperature of the workshop or laboratory, and, in case of dispute, at a temperature of (20±2) C.
4.3.2.4 Ewing test (anisotropy)
The earing test shall be carried out either in accordance with the relevant European Standard or as agreed
between the supplier and purchaser.
4.3.2.5 Other tests
If other mechanical or physical tests are required (e.g. thickness of coatings, lubricants), these tests shall be carried out either m accordance with the relevant European Standards or as agreed between supplier and purchaser.
4.3.3 Retests
4.3.3.1 Mechanical properties
If any of the test pieces first selected fail to meet the requirements for the mechanical tests, the following procedure shall be applied.
— If an error Is clearty identified, either in the test piece preparation or In the test procedure, then the corresponding result shall be disregarded and the testing resumed as Initially required
— If this is not the case, then two further specimens shall be taken from the same lot, one being from the same unit of the product (sheet, strip. etc.) from which the onginal specimen was taken, unless that piece of product has been withdrawn by the supplier.
