The maximum percent bending shall not exceed 5 at an average strain of 610500-×.There are two alternative means of load application:a) compression platens are connected to
the load cell and on the moving cross head. The parallelism of theseplatens shall be better than 0,01 mm, in the loading area and they shall be perpendicular to the load direction.NOTE 1The use of platens is not recommended for compression testing of 1D and 2D materials with low thicknessesbecause of buckling.NOTE 2A compliant interlayer material between the test specimen and platens can be used for testing macroscopicallyinhomogeneous materials to ensure uniform contact pressure.When the dimensions of specimen are such that buckling may occur, it is recommended to use an antibucklingtool such as one of those which are described in EN ISO 14126. This tool should not induce parasitic stressesduring loading of the specimen;b) grips are used to clamp and load the test specimen.The grip design shall prevent the test
