Description of key information
Not corrosive to aluminium alloy plate or steel plate
Additional information
The UN Transport test described in Part III, sub-section 37.4 has not been conducted as specified due to worldwide shortage of specific 2mm metal plates. However, the test method was negative for aluminium alloy plate and steel plate.
Justification for classification or non-classification
Recent investigations provide no evidence that the substance causes corrosion to aluminium alloy plate or steel plate. These data are supported by experience in use because an existing storage tank made of carbon steel (JIS SS400 (ex SS41)) equivalent to ASTM A283-Gr.D has not suffered major corrosion over a use period of 25 years. The latest annual inspection (July 2009) indicated that areas of corrosion no more than 0.5–1.0 mm in depth were present on the bottom plate but no evidence of corrosion was found on the sides of the tank. The calculated corrosion rate is calculated as 0.45 mm/year at 55 °C.
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).
