Usually, the electrical characteristics of qualified the power cord, its mechanical properties because line diameter meticulous and is bad, it in the handling and use process, often can withstand the mechanical accident happened accident to be damaged. Obviously, the quality control project aims to meet the requirements in the power cord electrical strength, still should be appropriately enlarging refrigerator irrelevant power diameter, so as to ensure it on the refrigerator in the normal use.
In the power cord and rated current electric property under the premise of qualified. Test the tensile (deformation) ability.
Safety technical indexes of project quality, belong to the power of quality inspection, are generally perform mandatory standards. With the increasing awareness of the national security, the safety standard data have been increasing trend.
