Product Description
Upto
Upto -40°C with Cold Bend and Cold Impact

Scope: Covers a method to determine resistance to bend of thermoplastic of electrometric insulation or sheath of electric cables at low temperatures and frost.

This test is applicable to specimen of diameter up to and including 12.5mm, above which this test is considered impracticable. For diameter above 12.5mm, cold impact test as specified in IS: 10810 (Part 21)-1984 Cold impact test is applicable.

Significance: Sometimes the cable have to be laid is the area of low temperature climatic conditions or frost. Due to constant exposure of the cable to the low temperature or frost conditions, the insulation or sheath of the cable will become hardened and stiff. However, this is a long-term effect. Such hardening or stiffness causes cracking of the insulation or sheath and may lead to the failure of the cable. In order to ascertain the suitability or with stand ability of the insulating or sheathing materials at low temperature or frost conditions (when the usage of the cable so warrants), this cold bend test is carried out.

Terminology:

As given is IS: 1885 (Part 32) –1971 ‘ Electro technical vocabulary Part 32 Cables, conductors and accessories for electricity supply’.

Apparatus:

  • Refrigerator: An electrically operated and thermostatically controlled cold chamber.
  • Thermometer: To monitor the low temperature inside the refrigerator.
  • Smooth Metal Mandrel of circular cross-section, as required.
  • Material: No material other than the test specimen is required for performing this test.
