Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 19.02.2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- Guideline study required by REACH regulation 1907/2006
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- Version / remarks:
- Council Regulation (EC) No 440/2008 of 30 May 2008 published on 31 May 2008, 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)
- Version / remarks:
- 2009
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: SOP 11800934 of testing facility
- Version / remarks:
- SOP 118 009 34, ”Bestimmung der Entzündlichkeit“, edition 4, valid from 02. Nov. 2011
- Deviations:
- no
- Principles of method if other than guideline:
- - Principle of test:
Determination of flammability
- Short description of test conditions: ignition of test item by gas flame for two minutes
- Parameters analysed / observed: burning by flame or smouldering - GLP compliance:
- yes (incl. QA statement)
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: Batch No: 585542
- Expiration date of the lot/batch: May 2019
- Purity test date: May 2016
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: room temperature - Key result
- Test procedure:
- burning rate test: preliminary screening test
- Burning time:
- >= 2 min
- Moisture (wt %):
- 20
- 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:
- not classified based on GHS criteria
- Conclusions:
- In the preliminary screening test following the EU and the UN method it was observed that the test item first tightened, then became black and expanded. When it tightened, the test item was liquid for a very short time.
No ignition occurred within two minutes.
Therefore, the test item should be considered as
- not highly flammable (for EU regulations)
- non-flammable solid (for UN regulations) - Executive summary:
This study was performed in order to determine the flammability of the test item.
As a first step, 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. It was observed, that the test item was liquid for a short time and then it became black and hard.
Second test:
In the preliminary screening test following the EU and the UN method, the test item was heated with the flame of a teclu burner for 2 minutes . The test item expanded a bit and became black. No sign of ignition occurred within two minutes.
Since ignition did not occur within two minutes, the test item was classified as not highly flammable (for EU regulations) and as non-flammable solid (for UN regulations), therefore no determination of burning rate was necessary.
