Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 01 September 2017 - 13 September 2017

- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- Test method according to EEC method A.10. GLP study.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Remarks:
- Test 1
- Burning time:
- 310 s
- Remarks on result:
- other: Negative result: burning time is longer than 4 minutes
- Key result
- Test procedure:
- burning rate test: preliminary screening test

- Remarks on result:
- other: Negative result: burning time is longer than 4 minutes
- Interpretation of results:
- other: Not classified (CLP Regulation EC no. 1272/2008)
- Conclusions:
- The tested material is not highly flammable in accordance with EU method A.10. criteria.
- Executive summary:
The flammability of the test item was determined according to EU Method A.10 (GLP study). In the preliminary screening test (3 replicates), the substance was formed into an unbroken strip or powder train about 250 mm long by 20 mm wide by 10 mm high on a non-combustible, non-porous and low heat-conducting base plate, and a hot flame was applied to one end of the powder train. Every sample tested ignited immediately after the ignition and the train burned completely. The burning time was longer than 4 min in each replicate. Thus, the result was negative and it was not necessary to conduct the burning rate test. The tested material is not highly flammable.
- 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
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
The test was not performed experimentally because practical experience exists at the sponsor and the test facility, e.g. when preparing test substance solutions for testing. The test substance in contact with water do not develop any gas at all, therefore is regarded as not being flammable in contact with water. - 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
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
The test was not performed experimentally because practical experience, e.g. in manufacture or handling shows that the substance does not ignite spontaneously on coming into contact with air at normal temperatures (i.e. the substance is known to be stable at
room temperature for prolonged periods of time (days). The test substance is therefore regarded as not being pyrophoric.

Test-1 |
310 |
The sample ignited immediately after the ignition. The train burned completely. The combustion was accompanied a large amount of smoke and an orange flame. Result: NEGATIVE |
Test-2 |
292 |
|
Test-3 |
325 |
In each test the time burning is longer than 4 minutes (according to the criteria of method A.10) therefore the result of the preliminary test is negative and it is not necessary to go to the next stage of determination (burning rate test).
Description of key information
Flammability: Key study. Method according to EU Method A.10, GLP study. The test item is not highly flammable.
Pyrophoric properties: Data waiving (study scientifically
not necessary / other information available): Practical experience in
manufacture and handling shows that the substance does not ignite
spontaneously on coming into contact with air at normal temperatures.
Flammability in contact with water: Data waiving (study
scientifically not necessary / other information available): The
substance is not classified as flammable in contact with water based on
the experience in handling / use which shows that the substance does not
react with water.
Key value for chemical safety assessment
- Flammability:
- not classified

Justification for classification or non-classification
Based on the available data, the substance is not classified as flammable solid according to CLP Regulation no. 1272/2008.
