Determining Flammability of CocoAbsorb Universal Organic Absorbent
Test for Determining Flammability of CocoAbsorb Universal Organic Absorbent
(Based on the Burning Rate Test as per Clause 22.214.171.124.3.2 in the UN recommendations)
Test: On pic.1, as per the test requirements, is a 200 mm strip (20mm wide by 10 mm high) of the CocoAbsorb Organic. It should be noted whether combustion propagates along 200 mm of the strip within the 2 minutes test period. Pic 2. - A hot flame (min. temperature 1000C) from a gas burner was applied for 2 minutes. On pic 3. it can be seen that the 200 mm strip of the product didn't burn within the 2 minute test period. During the test the product was smouldering only at the place exposed to the flame.
Conclusion: The above shows that CocoAbsorb Organic should not be classified as a flammable solid. CocoAbsorb Organic can be classified as Not Readily Combustible Solid of Division 4.1.
Test after absorption of oil spill (oil used: AWS – 68)
Test: The same Burning Test was repeated, this time comparing two products: CocoAbsorb Organic and Diatomite. After absorbing oil AWS 68, a hot flame from a gas burner was applied for 2 minutes. The final result can be seen above. The product Diatomite caught fire, see pic B. This is because Diatomite has less absorbing capacity than CocoAbsorb Organic and more of the oil was released when exposed to the hot flame. On the other side, CocoAbsorb Organic having a greater absorbing capacity didn’t release the absorbed oil when exposed to the hot flame and the product didn’t catch fire, it was only smouldering – see inset below (pictured far left).

Conclusion: The above shows that CocoAbsorb Organic has a greater absorbing capacity and is holding the absorbed oil better. However the two products should be used with caution when absorbing flammable spills.
