What is the fire rating on a PDL superboard



Fire rated to what standard? Our boards are tested to AS/NZS3439.3 and as part of this a clause is “Verification of resistance of insulating materials to
abnormal heat and to fire due to internal electric defects”
The tests in this standard are carried out in accordance with the appropriate IEC standards.
They include glow-wire temperature tests up to 960 deg C, where our boards must self extinguish in under 30 seconds
