- Executive summary:
The self-heating properties of the test item was assessed in the grewer oven screening test according to VDI 2263, Blatt 1, Kap. 1.4.1.
The substance has an onset-temperature of 313 °C in the grewer oven screening test. the maximum of the reaction is at 324 °C. The temperature increase ∆T is: 394.0°C. According to UN manual, the substance does not need to be classified, if the onset-temperatur in the grewer oven screening test is above 220 °C.
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 14.04.2015
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
- GLP compliance:
- no
- Other quality assurance:
- ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Remarks on result:
- substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period
- Interpretation of results:
- other: EU GHS criteria not met
- Conclusions:
- Because of the result of the preliminary test the test substance is not considered a flammable
solid because the outcome of the test is negatve. - Executive summary:
The test item was assessed or its flammability in a non-GLP study according to UN Test N.1. The substance did not burn during the preliminary screening test, therefore the main test is not required and the substance does not need to be classified as flammable solid.
- 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 organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied
- 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
- 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

Onset temperature: 313.0 °C
Temperature increase ∆T: 394.0°C
Result
1. Preliminary test:
Burning time ( 200 mm test distance): Burning time > 2 min, no metal powder. Therefore, the preliminary screening test is negative.
Because of the result of the preliminary test the test substance is not considered a flammable solid of division 4.1.
Description of key information
Flammability:
The test item was assessed or its flammability in a non-GLP study according to UN Test N.1. The substance did not burn during the preliminary screening test; therefore, the main test is not required, and the substance does not need to be classified as flammable solid.
Flammability, contact with water:
The study does not need to be conducted because the organic substance does not contain metals or metalloids and in addition 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.
Flammability, pyrophoric solids:
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.
Flammability, self-heating substances:
The self-heating properties of the test item was assessed in the grewer oven screening test according to VDI 2263, Blatt 1, Kap. 1.4.1.
The substance has an onset-temperature of 313 °C in the grewer oven screening test. the maximum of the reaction is at 324 °C. The temperature increase ∆T is: 394.0°C. According to UN manual, the substance does not need to be classified, if the onset-temperature in the grewer oven screening test is above 220 °C.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Justification for classification or non-classification
The substance did not burn during the preliminary screening test; therefore, the main test is not required, and the substance does not need to be classified as flammable solid.
In contact with water the test substance does not evolute gases. Therefore, the test substance is not regarded as hazardous according to EG-Guideline 92/69/EEC A.12 and in accordance with Regulation (EC) No 1272/2008.
Based on the physical state, the structural elements and the melting point the substance has not to be classified as pyrophoric solid in accordance with Regulation (EC) No 1272/2008.
The substance has not to be classified as self-heating substance because based on a screening test the classification of the substance as self-heating substance does not apply, the onset-temperature in the grewer oven screening test is above 220 °C (313 °C).
