- 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
- the study does not need to be conducted because the substance is known to be soluble in water to form a stable mixture
- Endpoint:
- pyrophoric solids
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

Results
Preliminary test
The test item could be ignited at room temperature using a flame as
ignition source but only burnt locally without propagation for a short
period of time.
Main Test
In the preliminary test the test item only burnt locally without propagation for a short period of time. Thus, the perfomance of the main test was not necessary.
Conclusion
The test item DMPSA-K2 could be ignited at room temperature
using a flame as ignition source but only burnt locally without
propagation for a short period of time.
The test item is classified as follows:
UN Transport Regulation:The test itemdoes not have to beclassified as readily combustible solid in class 4.1 according to the UN Transport Regulation.
GHS (CLP Regulation EC 1272/2008: Annex 1: 2.7):The test itemdoes not have to beclassified as flammable solid according to GHS / CLP Regulation EC 1272/2008 Annex 1: 2.7.
Results
Self-ignition in the Grewer oven
In the investigation of self-ignition in the Grewer oven the pure test
item showed an endothermic effect in the temperature range of
120 °C – 160 °C, which can be assigned to a drying of the test item
since it contains 4.45% water. A small exothermic effect was observed
starting at a temperature of 270 °C, which led to a maximum temperature
of approx. 302 °C (corresponding oven temperature 294 °C). Two further
exothermic effects were detected starting at temperatures of 320 °C and
390 °C, which led to maximum temperatures of approx. 389 °C
(corresponding oven temperature 359 °C) and approx. 428 °C
(corresponding oven temperature 418 °C), respectively. After the
measurement, the basket was filled with black-grey residue.
For the test item in mixture with Kieselguhr an endothermic effect was observed in the temperature range of 110 °C – 150 °C, which can also be assigned to a drying of the test item. An exothermic effect was observed starting at a temperature of 270 °C, which led to a maximum temperature of approx. 460 °C (corresponding oven temperature 299 °C). No further thermal were detected up to the maximum test temperature of approx. 418 °C. After the measurement, the basket was filled with a white to grey residue.
Table below summarizes the results of the Grewer oven experiment.

Conclusion
The pure test item DMPSA-K2 indicated self-heating at atmospheric pressure starting at a temperature of 270 °C. Due to the high onset temperature in the Grewer oven, it can be assumed that the UN Test N.4 using the 100 mm cube sample at 140 °C is negative.
On the basis of this result the tests on the self-ignition in the Grewer oven the test item is classified as follows:
UN Transport Regulation:
The test item does not have to be classified as self-heating substance in Class 4 Division 4.2 according to the UN Transport Regulation.
GHS / CLP Regulation EC 1272/2008 Annex 1: 2.11:
The test item does not have to be classified as self-heating substance according to GHS/CLP Regulation EC 1272/2008 Annex 1: 2.11.
Description of key information
Not flammable.
Not flammable on contact with water.
Not pyrophoric.
Not self-heating.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
During the study on flammability on ignition the test item ignited at room temperature but only burnt locally without propagation for a short period of time. Based on this, the substance is a non flammable solid.
Based on the chemical structure, pyrophoricity and flammability on contact with water are not expected.
Based on the Grewer oven test results, the substance is not self-heating.
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:
Based on the study on flammability on ignition the substance is a non flammable solid.
Based on the chemical structure, pyrophoricity and flammability on contact with water are not expected.
Based on the Grewer oven test results, the substance is not self-heating.
