DBP FlameTECH

Fire retardent V grade

DBP FlameTECH conveyor belting has rubber covers that provide good tear, cut, impact and abrasion resistance and is also fire retardant.

The belt is available in a complete range of multiply strengths and also with steel cord reinforcement. Tests carried out on DBP FlameTECH conveyor belting for determining fire retarding properties.

  1. Flame test – ISO 340:2013 test method
  2. Electrical conductivity of the belt surface – ISO 284:2012 test method
  3. Fire propagation test – EN 12881−1 test method

 

Safety level Standard norm/tests Belting name Risk
Level 1 hardly inflammable according to ISO 340 DIN EN 12882 2A-2B DBP FlameTECH EP or ST Level 1 Prevention of the propagation of accidental fire from a minor fire source aboveground and the risk of explosion due to the accumulation of static
electricity.
Level 1 hardly inflammable according to ISO 340 DIN EN 12882 2A-2B DBP FlameTECH EP or ST G1 – Level 1 Idem safety level 1 and additionally oil-resistant.
Level 2 DIN EN ISO 12882 according to customer specification DBP FlameTECH EP or ST Level 2 Prevention of the propagation of accidental fire from an extensive fire
source aboveground and the risk of explosion due to the accumulation of static electricity.
Level 3 DIN EN ISO 14973 according to customer specification DBP FlameTECH EP or ST Level 3 Prevention of the propagation of accidental fire from an minor or extensive
fire source underground, the risk of explosion due to the accumulation of static electricity and the risk of belt blockage.
