This standard provides a unified test method for determining the breaking force of various types of steel wire ropes, specifying a complete process from principles, sample preparation, test equipment, and test procedures to test reports. Its core involves preparing and securing samples using methods such as casting alloy, resin, or pressing sleeves on tensile equipment like electronic universal material testing machines. The steel wire rope specimen is then subjected to axial tensile force until it breaks, thereby measuring its actual breaking force. This method, modified and adopted from international standards, aims to ensure the accurate assessment of the safety performance of steel wire ropes in critical applications such as lifting and transportation.
