This method determines resistance to bend of Thermoplastic or Elastomeric insulation or sheath of electric cables at low temp. & frost. This test method is applicable to specimen of diameter up to 12.5mm
some times the cables have to be laid in the area of low temp. Climatic conditions or frost. Due to constant exposure of the cables o the low temp. or frost condition, the insulation or sheath of the cable will become hardened & stiff. In order to ascertain the suitability or withstandability of the insulating or sheathing materials at low temp. or frost conditions, this cold bend test is carried out.
