Additional information
The ECHA Guidance on information requirements and Chemical Safety Assessment Chapter R.7a: Endpoint specific guidance,
Version 2.4, February 2014, refers in this endpoint to the Guidance on the Application of the CLP Criteria, Version 4.0 November 2013, section 2.16 "CORROSIVE TO METALS".
In Chapter 2.16.4.1 of the CLP guidance it is stated that according to the classification criteria only substances and mixtures for which the application of the UN Test C.1 (described in part III, Section 37.4.1.1 of the UN-MTC) is relevant and needs to be considered. Application of classification criteria in the UN-MTC, Section 37.4 excludes solids, while ‘liquids and solids that may become liquids (during transport)’, have to be considered for such a classification.
The wording ‘solids that may become liquids’ was developed for UN RTDG Model Regulations classification purposes, and needs further explanation. Solids may become liquids by melting (due to increase in temperature). Solids having a melting point lower than 55 °C (which is the test temperature required in UN Test C.1) must then be taken into consideration.
The substance is a white to minimal yellow powder at room temperature and atmospheric pressure, cf.4.1 Appearance.
The test item is melting under decomposition from 230 °C at ambient pressure. , cf. 4.2 Melting point.
The requirement for the testing the corrosivity to metals does not apply to the substance as no melting point < 55°C could be observed.
Therefore, testing is technically not possible. The study is waived according to REACH Annex XI Nr. 2 "Testing is technically not possible .
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.
