Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2017-04-06
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- 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:
- GHS criteria not met
- Conclusions:
- No ignition was observed throughout the course of the test. The test item was considered as not highly flammable (for EU regulations) and non-flammable solid (for UN regulations), respectively. No observations were made which might cause doubts concerning the validity of the study outcome.
- Executive summary:
A study was performed according to Regulation (EC) No. 440/2008, method A.10 and UN method N.1, in order to determine the relative auto-flammability of the test item. First, a safety test was performed. A small amount of the test item was heated on a magnesia groove with a gas burner in order to derive safety precautions. The test item melted into a clear yellow-brown liquid. The liquid burned with orange flame leaving no residue on the magnesia groove. In the preliminary screening test following the EU method and UN method, the test item was heated with the flame of a Teclu burner. The test item melted into a clear liquid. The colour of the liquid changed into brown. No signs of flammability were observed. No ignition occurred within two minutes.
Therefore, the test item was considered as 'not highly flammable' (for EU regulations) and 'non-flammable solid' (for UN regulations).
Reference
Safety Pre-Test
The test item melted into a clear yellow-brown liquid. The liquid burned with orange flame leaving no residue on the magnesia groove.
Preliminary Screening Test
The test item melted into a clear liquid. The colour of the liquid changed into brown. No signs of flammability were observed. No ignition occurred within two minutes.
Description of key information
The substance has not to be classified as flammable gas, flammable liquid, flammable solid, pyrophoric solid, pyrophoric liquid, flammable in contact with water, flammable aerosol or self-heating substance.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Flammable solids (reference 4.13-1)
A study was performed according to Regulation (EC) No. 440/2008, method A.10 and UN method N.1, in order to determine the relative auto-flammability of the test item. First, a safety test was performed. A small amount of the test item was heated on a magnesia groove with a gas burner in order to derive safety precautions. The test item melted into a clear yellow-brown liquid. The liquid burned with orange flame leaving no residue on the magnesia groove. In the preliminary screening test following the EU method and UN method, the test item was heated with the flame of a Teclu burner. The test item melted into a clear liquid. The colour of the liquid changed into brown. No signs of flammability were observed. No ignition occurred within two minutes. Therefore, the test item was considered as 'not highly flammable' (for EU regulations) and 'non-flammable solid' (for UN regulations).
Flammable gases (reference 4.13-2)
The test item is a solid at ambient conditions. This hazard class is only applicable for gases. Thus, the substance was not considered for classification as flammable gas.
Flammable liquids (reference 4.11-1)
The test item is a solid at ambient conditions. This hazard class is only applicable for liquids. Thus, the substance was not considered for classification as flammable liquid.
Pyrophoric solids (reference 4.13-3)
In accordance with section 2.10.4 Annex I of Regulation (EC) No 1272/2008 and ECHA guidance on the application of CLP Criteria section 2.10.2 the classification procedure for pyrophoric solids need not to be applied when experience in manufacturing or handling shows that the substance or mixture does not ignite spontaneously when coming into contact with air at normal temperatures. Based on the experience in handling and use the substance is not known to ignite spontaneously when coming into contact with air at normal temperatures. Thus, no study was conducted and the substance was not considered for classification as pyrophoric solid.
Pyrophoric liquids (reference 4.13-4)
The test item is a solid at ambient conditions. This hazard class is only applicable for liquids. Thus, the substance was not considered for classification as pyrophoric liquid.
Substances which, in contact with water, emit flammable gases (reference 4.13-5)
In accordance with column 2 of REACH Annex VI and with Regulation (EC) No 1272/2008 Annex I section 2.12.4.1(b) the classification procedure for this hazard class need not to be applied. Based on the experience in handling and use the substance does not react with water and in addition the test substance is not pyrophoric. Thus, no study was conducted and the substance was not considered for classification.
Self-heating substances and mixtures (reference 4.13-6)
In accordance with section 2.11.4.2 of Regulation (EC) 1272/2008 the item was not considered to be a self-heating substance, because no self-ignition could be stated up to 400 °C in the ZPA-3 oven (test performed according to test method A.16). Thus, no self-heating test was performed for the test item.
Flammable Aerosols
Section 2.4.2 of Guidance on the application on the CLP Criteria state as follows: “Aerosols, this means aerosol dispensers, are any non-refillable receptacles made of metal, glass or plastics and containing a gas compressed, liquefied or dissolved under pressure, with or without a liquid, paste or powder, and fitted with a release device allowing the contents to be ejected as solid or liquid particles in suspension in a gas, as a foam, paste or powder or in a liquid state or in a gaseous state." Thus, as the substance does not meet the definition for aerosol, the test for aerosols was waived. Consequently the substance has not to be considered for classification for this hazard class.
In conclusion the substance has not to be considered as flammable gas, flammable liquid, flammable solid, flammable in contact with water, flammable aerosol, pyrophoric solid, pyrophoric liquid or self-heating substance.
Justification for classification or non-classification
In accordance with Annex I Section 2.2, Section 2.3, Section 2.6, Section 2.7, Section 2.9, Section 2.10 Section 2.11, Section 2.12 of Regulation (EC) No 1272/2008 the test item has not to be classified as readily combustable solid, flammable gas, flammable liquid, pyrophoric solid, pyrophoric liquid, substances which emits flammable gases in contact with water, aerosol and self-heating substance.
