Test (step 4) sample weights: 10 g in each of 2 test runs. Total
quantity of liberated gas in run 2: 0.1 L/kg h after 60 min, afterwards
0 L/kg h until 420 min. No liberated gas in run 1 until 420 min. The
gas production based on one kilogram of test substance and a one-hour
test period was considerably less than 1 L/kg h in all test runs. Thus,
the test item does not liberate gases in hazardous amounts when tested
according to this procedure.
The preliminary test was clearly negative. The main test had not to be performed.
Test in the 10 cm cube sample at an oven temperature of 140 °C:
966.4 g of the test item were filled in the sample container. The
exothermic effect started after approximately 13 hours. Due to the
ongoing exothermal effect the measurement was not stopped after 24
hours. The maximum temperature of the test item after 45 hours (complete
measurement time) was 375 °C. After the measurement the test item was
black and foamy filling the mesh wire basket and partially the oven.
Therefore it was not possible to determine the mass loss.
The temperature of the test item exceeded 200 °C. Due to the positive
result (AT > 60 K) at 140 °C a test in a wire netting cube of 2.5 cm
edge length at 140 °C had to be performed
Test in the 2.5 cm cube sample at an oven temperature of 140 °C:
11.6 g of the test item were filled in the sample container. No
exothermic effect was observed during the measurement.
After the measurement the mesh wire basket contained approximately
10wt.% less test item than at the start. The test item was discoloured
to brownish after the measurement. The temperature of the test item did
not exceed 200 °C. Due to the negative result at 140 °C a test in a wire
netting cube of 10 cm edge length at 120 °C had to be performed.
Test in the 10 cm cube sample at an oven temperature of 120 °C:
940.2 g of the test item were filled in the sample container. No
exothermic effect was observed during the measurement. After the
measurement the mesh wire basket showed no significant mass loss of the
test item.
The temperature of the test item did not exceed 180 °C. Therefore no
further tests were necessary.
Due to the negative result in a wire netting cube of 10 cm edge
length at 120 °C and under the assumption that the product is not
classified in any class with a higher precedence of hazard, the test
item is exempted from division 4.2 (self-heating substances) if
transported in packages of not more than 3 cubic meters volume.
Otherwise the test item has to be classified as division 4.2
(self-heating substances) packing group 3.
The preliminary test was clearly negative. The main test had not to be performed.
Observation was made at a constant temperature for 24 hours to determine whether or not spontaneous ignition occurs and the temperature of the sample exceeds 200 °C, respectively. If a negative result is obtained no further test is necessary. In case of a positive result further testing is required.
The test substance showed no exothermic reactions within the specified period of 24 hours. After 50 hours storing the substance begun to react exothermal. The maximum reaction temperature was 359 °C. An additional test in a smaller volume was not necessary.
The test substance does not undergo spontaneous combustion in the
1 Ltr. Bowes-Cameron-CageTest at 140 °C in the sense of the
UN-Recommendations on the transport of dangerous goods.
Description of key information
non-flammable on ignition
non-pyrophoric
does not liberate gases in hazardous amounts on contact with water
not self-heating if transported in packages of less than 3 cubic metres volume
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
The substance is non-flammable on ignition on the basis of the outcomes of EU A.10 tests. It is non-pyrophoric based on experience with handling and use. The substance does not liberate hazardous amounts of gases on contact with water. Results of the self-heating tests (UN N.4) yield non-classification, provided the substance is transported in packages of the volume less than 3 cubic metres.
Justification for classification or non-classification
The available data on flammability of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008 and are therefore conclusive but not sufficient for classification: it was experimentally proven that the substance was non-flammable on ignition (EU Method A.14), did not liberate hazardous amounts of gases on contact with water (EU Method A.12) and according to experience in handling and use, it is non-pyrophoric. The substance is not self-heating according to the outcome of the UN N.4 test, however this is restricted only to packages up to 3 cubic metres.
Otherwise the test item has to be classified as division 4.2 (self-heating substances) packing group 3, according to UN RTDG, and as a self-heating substance Cat. 2 according to CLP.
