Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 11 October 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- 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: Sponsor and G316533
- Expiration date of the lot/batch: 25 March 2018
- Purity test date: 22 August 2017 - Key result
- Test procedure:
- burning rate test: preliminary screening test
- Moisture (wt %):
- 0.84
- 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
- Remarks:
- Sample began to melt and it ignited with a medium size, orange, localised flame, this sustained for about 3 seconds after test flame was removed before extinguishing
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- From the preliminary screening (S/T) test the sample was seen to briefly ignite and therefore no further testing is required.
Reference
If the burning time in the preliminary screening test is less than 4 minutes (40 minutes for metal powders), over a 200 mm distance, then the full range of burning rate tests are carried out unless no propagation is observed, otherwise no further testing is required. Materials are to be considered as highly flammable, when the time of burning in one of the six tests carried out according to the test procedure described is less than 45 seconds. Powders of metals or metal alloys are considered to be highly flammable when they can be ignited and the flame of the zone of reaction spreads over the whole sample in ten minutes or less.

Description of key information
From the preliminary screening (S/T) test the sample was seen to briefly ignite and therefore no further testing is required.
Key value for chemical safety assessment
