VERTICAL BURNING TEST (UL-94)
- Classifies plastics according to how they burn in various thicknesses
UL-94 vertical burning test results
- 10 seconds of flame application.
- If flaming of polymer stops, then apply flame another 10 seconds.
- 5 measures per sample
Criteria conditions V0 V1 V2 Afterflame time for each individual specimen t1 or t2 10 s 30 s 30 s Total aferflame time for any condition set (t1 plus t2 for the 5 specimens) 50 s 250 s 250 s Afterflame plus afterglow time for each individual specimen after the second flame application (t2 + t3) 30 s 60 s 60 s Afterflame or afterglow of any specimen up to the holding clamp No No No Cotton indicator ignited by flaming particles or drops No No Yes Otherwise: No Rating
- Test Conclusions
- All samples showed similar behaviour in the cone calorimeter test.
- When ADINS is added into the PP/ intumescent formulations the Total Smoke Production and the Smoke Density is reduced in all cases.
- In the UL-94 test we can see how the samples not drip.
- In this formulation, with ADINS Clay B25 the Total Smoke Production is 60% reduced.
