Fire collars for plastic drainage - do they work?

Fire Safety Comparison Test, commissioned by IZEG (association of cast iron manufacturers in Germany) in 2004 to understand the effects of fire and the behaviour of different drainage systems in industrial, commercial and public buildings. This shows how Saint-Gobain PAM cast iron systems are proven among the safest on the market in their fire resistance and how passive fire collars used in the test remained inactive, with molten droplets from the HDPE passing through them and generating further fire outbreak on the floor below.
