Test Background
Weight loss test methods and thermal stability tests for polyvinyl chloride blends are applicable to the most common types of insulation and sheathing materials for power distribution and communications cables and optical cables, wires and cords, including polymer insulation and sheathing materials for ship and offshore cables and optical cables.
Zhongke Testing Reliability Experiment Center has environmental testing capabilities for various cables and optical cables, and provides professional weight loss testing and thermal stability testing services for polyvinyl chloride compound insulation and sheathing materials.
Scope of tests
The most common types of insulation and sheathing materials for power distribution and communication cables and optical cables, wires and cords, including polymer insulation and sheathing materials for ship and offshore cables and optical cables, as well as insulation and sheathing materials for elastomers, polyvinyl chloride, polyethylene, polypropylene, etc.
Test method
Insulation and sheath weight loss test: insulation weight loss test, sheath weight loss test Insulation and sheath;
Thermal stability test;
The average of the thermal stabilization times of the three samples should not be lower than the value specified in the relevant cable product standards.
