Fire retardent V grade conveyor belts
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.
| 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. |
