Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- other: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- weight of evidence
- Study period:
- 2015-2016
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods
- Remarks:
- The complete read across justification is detailed in section 13. Source study has reliability 1.
- Qualifier:
- according to guideline
- Guideline:
- other: UN Manual of Tests and Criteria, Part Ill, Test N .1.
- Principles of method if other than guideline:
- The substance in its commercial form is made into a pile. An attempt is then made to ignite the sample under defined conditions and the burning time is measured.
- GLP compliance:
- yes
- Test procedure:
- ignition time on contact with air
- Remarks on result:
- no ignition on contact with air (not further specified)
- Test procedure:
- ignition time on contact with air
- Remarks on result:
- no ignition on contact with air (not further specified)
- Remarks on result:
- no reaction with water observed
- Interpretation of results:
- other: non flammable according to the CLP Regulation (EC 1272/2008)
- Conclusions:
- The test substance is considered to be non highly flammable.
- Executive summary:

- Conclusions:
- Non flammable.
- Executive summary:
Method
The test has been conducted according to the EU Method A.10 (Flammability (Solids)).
No other information on method is available. Available data derived from migrated NONS file, as per Article 25(3) request, with permission to refer granted by ECHA.
Results
Based on the negative result in the test, the substance is classified as a NON flammable solid.
Referenceopen allclose all
Preliminary test
Localized burning or glowing with practically no spreading. Therefore, the preliminary screening test is negative.
Main test
Omitted due to result of preliminary test.
Description of key information
Non highly flammable upon ignition.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
No data on test substance itself was available. A weight of evidence approach was adopted, using Similar Substance 01 and 02 as read across substances. In particular, Similar Substance 01 is an isomer of test substance, differing only for the position of one functional group on an aromatic ring; Similar Substance 02 has structural similarity with test susbtance. A detailed justification of the read across process is attached in section 13.
Based on migrated information from NONS file, as per Article 25(3) request, Similar Substance 01 resulted as non flammable in a test conducted according to EU method A.10. Permission to refer is granted by ECHA.
As for Similar Substance 02, flammability was assessed according to UN Manual of Tests and Criteria, Part Ill, Test N .1. Upon ignition, test substance was localized burning or glowing with practically no spreading,
Justification for classification or non-classification
According to the CLP Regulation (EC 1272/2008) powdered, granular or pasty substances or mixtures (except powders of metals or metal alloys — see 2.7.2.2) shall be classified as readily combustible solids when the time of burning of one or more of the test runs, performed in accordance with the test method described in Part III, sub-section 33.2.1, of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, is less than 45 seconds or the rate of burning is more than 2.2 mm/s.
Since no combustion was observed during the flammability test period, both Similar Substance 01 and 02 are not classified according to the CLP classification criteria.
Based on a read across approach, Direct Blue 273 is considered as non highly flammable and not classified within the CLP Regulation.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
