Endpoint:

substances / mixtures which in contact with water emit flammable gases

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water

Version / remarks:

revision 6

GLP compliance:

no

Specific details on test material used for the study:

Storage conditions: ambient temperature (10 to 30 °C)

Test procedure:

100 mm sample cube at 140°C

Max. temp. reached:

138

Induction time (h):

8

Result:

negative outcome (no effect observed)

Remarks:

No effect was observed for 68 h after induction time

For the test in the 10 cm cube at an oven temperature of 140 °C ± 2 °Can amount of 813.4 g of the test item was filled in the sample container. The test item temperature reached almost the oven temperature (138 °C) after approximately 8 hours. The test item temperature was approximately 1 K below the oven temperature during the experiment and the test item showed no exothermal effects. The maximum temperature of the test item was 138 °C. After approximately 68 hours the test was stopped.

After the measurement the mesh wire basket contained approximately 4 % (w/w) less test item than at the start. The remaining test item was slightly discoloured.

The temperature of the test item did not exceed 200 °C during the whole test and showed also no spontaneous ignition. Due to the negative result at 140 °C ± 2 °C (10 cm cube) the test item has not to be classified as "self-heating substance" in the sense of UN Manual of Test and Criteria, Method N.4, and has not to be classified as "self-heating substance" according to chapter 2.11 of the GHS (CLP) regulations.

Description of key information

Substance is not a highly flammable solid (EU Method A.10., Burning rate preliminary screening test).

No pyrophoricity.

No flammability on contact with water.

Not self-heating (UN Manual of Test and Criteria, Method N.4, Test for self-heating substances)

Key value for chemical safety assessment

Flammability:

not classified

Additional information

The flammability of the substance was determined according to EU Method A.10.

The performance of the main test was not needed since the test item could not be ignited with a flame. According to EC No. 440/2008, Method A.10. the test item is not a highly flammable solid.ance of the main test was not needed since the test item could not be ignited with a flame. According to EC No. 440/2008, Method A.10. the test item is not a highly flammable solid.

The self-heating of the substances was tested according to UN Manual of Test and Criteria, Method N.4.

The temperature of the test item did not exceed 200 °C during the whole test and showed also no spontaneous ignition. Due to the negative result at 140 °C ± 2 °C (10 cm cube) the test item has not to be classified as "self-heating substance" in the sense of UN Manual of Test and Criteria, Method N.4.

Based on the chemical structure and experience in handling and use, pyrophoricity and flammability on contact with water are not expected.

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: No propagation of burning in a test according to EU Method A.10. Due to the fact that a negative result was obtained in the test using a 10 cm sample cube at 140 °C ± 2 °C the test item has not to be classified as "self-heating substance" according to UN Manual of Test and Criteria, Method N.4 and chapter 2.11 of the GHS (CLP) regulations. Based on the chemical structure and experience in handling and use, pyrophoricity and flammability on contact with water are not expected.
