- yes (incl. QA statement)
- 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:
- The test item was not flammable under the conditions of the test.
- Executive summary:
The test substance was assessed for flammability in a GLP study according to EU method A.10, The United Nations Document, Recommendation of the Transport of Dangerous Goods, Manual of Tests and Criteria (Test N.1.) and the HSE Code of Physico-Chemical Properties 1982. It was determined that ammonium pentaborate should be classified as "not a highly flammable solid".

From the preliminary screening test the sample was seen not to ignite and therefore no further testing was required.
Initially the sample slowly melted to a thick clear gel then glowed pale red while in contact with the ignition source. No propagation of this reaction was observed.

Description of key information
The test substance was assessed for flammability in a GLP study according to EU method A.10, The United Nations Document, Recommendation of the Transport of Dangerous Goods, Manual of Tests and Criteria (Test N.1.) and the HSE Code of Physico-Chemical Properties 1982. It was determined that ammonium pentaborate should be classified as "not a highly flammable solid".
Further, a study was performed according to UN Recommendation on the Transportation of Dangerous Goods, Manual of Tests and Criteria for substances of Class 4, Division 4.3, on the emission of flammable gases on contact with water. It was determined that ammonium pentaborate is not classified as a material of class 4.3 (according to the UN Transport of Dangerous Goods Recommendation).
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
Justification for classification or non-classification
The test material does not meet the criteria for classification and will not require labelling in accordance with European Regulation (EC) No. 1272/2008, amending Regulation EC No. 1907/2006 (REACH).
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
