Section 4.09 of SAE J2031 specifies the low temperature test for cable. The cable is conditioned at low temperature and then subjected to mechanical stress (bending) to evaluate cold flexibility and insulation integrity.
Low temperature performance is critical for automotive cables that must remain flexible during cold-weather starting and operation.
This test evaluates the performance of wire when exposed to low temperature conditions as specified in AS654. Specimens are conditioned at the specified low temperature, then subjected to mechanical stress (typically bending or impact) while still cold to evaluate cold-weather performance.
Low temperature testing is critical for products used in aerospace, military, and outdoor applications where exposure to extreme cold can cause insulation materials to become brittle and crack.
