| Fire Retardant Properties |
| IEC-61111 Standard |
IS: 15652:2006 Standard |
| i.)The propagation of the flame on the test piece shall be observed for 55 second after the withdrawal of the testing flame. |
i.) Fire should extinguish within 5 second after removal of blue flame. |
|
| |
| As you will observe from above that the fire retardant properties as per IS: 15652:2006 is much better which is prime concern for safety for Oil-Rig area , thickness of the mat is much less & it is pastable type & have good Mechanical properties to withstand load & smooth breaker trolleys movement. |
