Administrative data
Link to relevant study record(s)
- 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
- 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
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 18 Feb-15 Apr 2014
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- Qualifier:
- according to guideline
- Guideline:
- other: United Nations (UN) Test N.1: “Test Method for Readily Combustible Solids”, 2009.
- Deviations:
- yes
- Remarks:
- No wetting zone was applied beyond the 100 mm timing zone during the burning rate test. It was technical not possible to prepare a wetting zone due to the high solubility of the compound.
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- GLP Compliance Monitoring Program, Health Care Inspectorate, Ministry of Health, Welfare and Sport, Den Haag, The Netherlands
- Test procedure:
- burning time (test type not further specified)
- Remarks:
- or specified in description of method
- Burning time:
- 38 s
- Remarks on result:
- other: burning rate 2.63 mm/s
- Interpretation of results:
- Category 1 (flammable solids) based on GHS criteria

Preliminary test
The flame of the gas burner did ignite the test substance pile. The test substance melted, burned with a blue yellow flame and turned into a brown residue. After the pile had burned a distance of 50 mm, the time of burning over a distance of 200 mm was measured to be 71 seconds (i.e. 2.8 mm/s).
Burning rate test
After the pile had burned a distance of 80 mm, the burning time over 100 mm was measured to be 38 seconds. The test was performed once, since it confirmed the preliminary screening test in which two positive results were observed.
Description of key information
flammable on ignition (EU A.10, UN N.1 without wetting zone application)
non-flammable on contact with water (based on structure and experience in handling and use, in accordance with guidelines EU A.12 and UN N.5)
non-pyrophoric (based on structure and experience in handling and use, in accordance with guidelines EU A.13 and UN N.2)
Key value for chemical safety assessment
- Flammability:
- flammable
Additional information
The influence of a wetted zone, as required according to the guideline UN.1, could not be investigated because of a high solubility of the test substance in water.
Justification for classification or non-classification
According to Regulation (EC) No 1272/2008 on classification, labelling and packaging (CLP) of substances and mixtures, the substance is considered to be a flammable solid, Category 1, and as R11 according to Directive 67/548/EEC. The Category 1 is assumed as the worst-case scenario, because the influence of the wetted zone cannot be investigated for technical reasons. Based on the chemical structure and experience in handling and use, pyrophoricity and flammability on contact with water are not expected.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
