Type of information:

experimental study

Adequacy of study:

key study

Study period:

22 SEP 2021 - 29 SEP 2021

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Reason / purpose for cross-reference:

reference to same study

Qualifier:

according to guideline

Guideline:

other: EU Method A.16 (Relative Self-Ignition Temperature for Solids)

Version / remarks:

Official Journal of the European Union L142 of 31 May 2008

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Test procedure:

other: screening

Result:

negative outcome (no effect observed)

Remarks on result:

other: The sample did not self-ignite up to 600 °C oven temperature

Interpretation of results:

other: EU GHS criteria not met

Conclusions:

The sample did not self-ignite up to 400 °C oven temperature, as only a parallel temperature increase of the oven and the sample was noted. Thus, no self-ignition/self-heating was noted under the conditions of this test.

Executive summary:

A self ignition test was performed according to EU Method A.16 under GLP compliance. In the assay a defined amount of the test item was placed into an oven at ambient temperature; the temperature/time curve was recorded while the temperature of the oven was slowly (at a rate of approximately 0.5 °C/min) increased up to 400 °C. For the purpose of this test, the temperature of the oven at which the sample temperature reaches 400 °C by self-heating is called the self-ignition temperature. Three separate tests were performed. In the course of this study the test item did not self-ignite up to 400 °C as only a parallel temperature increase of the oven and the sample was noted. Thus, no self-ignition/self-heating was noted under the conditions of this test.

Justification for data waiving:

other:

Reference 3

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

Reference 4

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

Description of key information

Flammability, self-heating:

A self ignition test was performed according to EU Method A.16 under GLP compliance. The sample did not self-ignite up to 400 °C oven temperature, as only a parallel temperature increase of the oven and the sample was noted. Thus, no self-ignition/self-heating was noted under the conditions of this test. It also doesn't meet the EU GHS criteria.

Flammability, contact with water:

The test is scientifically not necessary, because the ecperience 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.

Flammability, pyrophoric solids:

The study is scientifically not necessary, because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days), therefore, it can be concluded that the test material exhibit no risk for pyrophoricity.

Flammability, flammable solid:

The study is technically and scientfically not feasible because it is an oxidising solid. Oxidising solids should not be considered for classification as flammable solids since flammability is an intrinsic hazard in these class.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

The sample did not self-ignite up to 400 °C oven temperature, as only a parallel temperature increase of the oven and the sample was noted. Thus, no self-ignition/self-heating was noted under the conditions of this test and therefore the EU GHS criteria are not met.

Since the test item is oxidising solid, it should not be considered for classification as flammable solids because the flammability is an intrinsic hazard in these class.

Based on the physical state, the substance has not to be classified as flammable in contact with water, nor as pyrophoric solid.
