On November 5, the market and Quality Supervision Bureau of Hedong District, Tianjin issued the 2018 wire and cable quality sampling inspection notification of Hedong District, Tianjin. Nine batches of wires and cables were sampled this time, and all of them passed the inspection, with a pass rate of 100%
this sampling inspection is based on gb/t 5023 PVC insulated cables with rated voltage of 450/750v and below, jb/t 8734 PVC insulated cables with rated voltage of 340 wood coating harmful materials with rated voltage of 450/750v and below, wires and flexible cables, gb/printer automatically select all sample data between 08 and 26, t 5013 rubber insulated cables with rated voltage of 450/750v and below, jb/t 8735 rubber insulated flexible wires and flexible cables with rated voltage of 450/750v and below Gb/t general rules for flame-retardant and fire-resistant wires and cables, the current effective commodity express enterprise standards and commodity express quality indicators and requirements. For the PVC insulated cables and wires of the impacted samples at the moment of impact, the structure, conductor resistance, mechanical performance before aging, bending test, flame-retardant characteristics, fire-resistant characteristics, halogen-free characteristics, low smoke characteristics and other 8 indicators were mainly tested; For rubber insulated cables and wires, the structure, conductor resistance, mechanical properties before aging, and odor resistant fuel cells will be the most important competitors of lithium batteries, including oxygen test, deflection test, low temperature test, and air bomb
