Our comparison index on Impact Resistance ranks the materials out of 20 = best. The performance comparison is done at the ‘most unfavourable’ conditions for each material. In practice this may be harsh on some of the rankings. Impact strength decreases with decreasing service temperature. The minimum service temperature in turn being limited by the extent to which the material is subjected to Impact. Therefore materials ranked differently here at their minimum service temperature may rank very similarly for impact at their maximum service temperature in normal conditions.
