- Conclusions:
- Self-heating of Lowinox® 22IB46 was determined in accordance with UN Test N.4 “Test Method for Self-heating Substances”.
From the negative result obtained at 140°C using a 10 cm sample cube, it was concluded that Lowinox® 22IB46 is not a self-heating substance. - Executive summary:
The purpose of the study was to determine the physico-chemical properties for Lowinox® 22IB46.
The test item was exposed to air at 140 °C using a temperature controlled laboratory oven, a cubic stainless steel wire 10 cm sample container, NiCr/Ni thermocouples and a temperature recording device. The study was performed in accordance with the following test guideline:
United Nations (UN), UN no. ST/SG/AC.10/11/Rev.5: Recommendations on the Transport of Dangerous Goods, Part III: Classification Procedures, Test Methods and Criteria Relating to Class 2, Class 3, Class 4, Division 5.1, Class 8 and Class 9, Test N.4: “Test Method for Self-heating Substances”, 2009.
A negative result was obtained. No spontaneous ignition occurred and no significant exothermic effect of the test item was observed. It demonstrated that the test item is “not a self-heating substance”. According to the UN guideline, no further testing is required.
After the experiment, the test item had turned into a white to off-white residue. This slight colour change indicated that the test item decomposed and/or reacted during the experiment.
Self-heating of Lowinox® 22IB46 was determined in accordance with UN Test N.4 “Test Method for Self-heating Substances”.
From the negative result obtained at 140°C using a 10 cm sample cube, it was concluded that Lowinox® 22IB46 is not a self-heating substance.
