ZY6282 NES713 Cable Testing Equipment , Smoke Toxicity Insulation Resistance Test
Meet the standard:
The toxicity index standard of combustion products was measured by the test of small sample combustion in JB/T10707 and NES713.
Main parameters:
The progress of the combustion test can be observed through the enhanced plastic observation window during combustion test.
Specially designed door lock, convenient switch box door;
Manual/automatic test mode, free choice;
Timer control, automatic ignition and ignition are automatically extinguished;
Automatic exhaust mode, which can automatically eliminate the smoke generated during the test when the test is completed.
Automatic cycle mode, combustion produced gas under the control of the cycle of the timer.
Combustion furnace preheat to 800 ℃, the cable material contain toxic substances will be burning respectively, collect each poisonous gas recycle gas emissions rate, then the content of each poisonous substances through the calculation of chemical analysis, the index is expressed as the number of toxicity. The greater the toxicity index, the higher the toxicity of this material.
The toxicity index of the non-halogen cable material is less than 5. It is worth noting that the low smoke zero halogen material burns also will produce toxic CO, if material containing P, N, S, toxic gases generated more, so halogen-free cable is called a non-toxic cable, shall be referred to as the low toxicity cable. CM, CMR and CMP cables are made of halogen, CM and CMR cables as the base material of polyvinyl chloride (PVC), and PVC material containing chlorine. CMP cables are usually based on Tetrafluoroethylene(FEP), while FEP materials contain fluoride. Such a gas containing halogen cable toxicity is a halogen-free cable times larger, in fire safety to save a lot of hidden trouble, may lead to the scene of the fire most of the casualties is not burned but poison gas suffocation death. No gas analyzer.
