Principle
Pre-selection of samples
Selection of samples and preparation of test pieces
One sample having a length suitable for the bending test described in
Each sample of core thus obtained shall be wound, in three turns, on a mandrel, the diameter of which is three times that of the core.
From each sample of core which has been straightened out after the third cycle of bending operations, a test piece having a length of about 150 mm shall be taken from that part of the core which has actually been wound.
