Tensile and bending test samples are taken in transverse way; shock test sample is taken in longitudinal way; Rpo ?., is applied when yielding is not distinctive. 2. Bending sample breadth is >20mm. 3. Shock test is only fit for products with thickness more than 12.0mm. 4. Impact value is a average value from three testing samples, of which only one sample testing value is permitted to be smaller than setup, but not less than 75%.
