Description of key information
The aqueous solution of perchloric acid at 65% was found to be non explosive in a test performed according to the EU method A14.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Anhydrous perchloric acid presents an explosion hazard because perchlorate group (ClO4-) is a chemical group associated with explosive properties. However, the substance is manufactured and used in aqueous solution of perchloric acid which has been found to be not explosive in the key study as summarised below:
In a GLP study (Défitraces, 2013), the explosion properties of Aqueous solution of Perchloric acid at 65% were tested using a A.14 method according to the Commission Regulation (EC) N°440/2008. The method provides a testing scheme to determine whether a liquid presents a danger of explosion when submitted to the effect of a flame and a shock.
Mechanical sensitivity (shock): Six negative assays were recorded, no mechanical sensitivity was noted with the 40-J force.
Thermal sensitivity: Six negative assays were recorded, no thermal sensitivity was noted with the test item.
Aqueous solution of Perchloric acid was not considered to have explosive properties under our experimental conditions.
Justification for classification or non-classification
The explosive properties are not reported in the official classification of perchloric acid in the Regulation (EC) No 1272/2008 (Annex VI Table 3.1).
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.
