What are the mechanical performance testing standards for J1939 9 pin 1 to 2 splitter Y cable?
The performance testing standards for J1939 splitter Y cable are mainly based on the SAE J1939 protocol series, and the specific mechanical performance testing standards are as follows:
Mechanical Performance Testing Standards
Tensile strength and elongation testing: Referring to standards, tensile tests are conducted on the insulation and sheath materials of cables to measure their tensile strength and elongation at break before and after aging, ensuring that the materials have sufficient strength and flexibility to withstand the tensile forces during installation and use.
Bending test: According to relevant cable standards, the cable is bent around a cylinder of a specified diameter to check for cracks, damages, and other issues in the insulation and sheath of the cable, as well as conductor fractures, in order to evaluate the performance of the cable in a bent state.
Wear resistance test: Simulate the friction situation that cables may experience in actual use, and conduct wear resistance tests according to relevant standards. For example, use a wear resistance testing machine to conduct a certain number of friction tests on the surface of the cable to check the degree of wear on the cable surface and ensure the integrity of the insulation and sheath.
Vibration resistance test: According to the application scenario and relevant standard requirements, the cable is installed on a vibration table and subjected to vibration tests of different frequencies, amplitudes, and times to check whether the cable connection is loose, whether the conductor is broken, whether the insulation is damaged, etc., to ensure the reliability of the cable in a vibration environment.
