Additional information
The self-heating in air was studied in a screening test according to Grewer (Grewer-Oven-Test, VDI 2263-1) with the pure test substance and additionally with a 1:1 kieselguhr mixture.
In this test with the pure product and the kieselguhr mixture an exothermal effect was recorded starting at 200 °C that led to a maximum temperature of more than 600°C.
Due to these results from the Grewer-Oven Test an UN N.4 test (Bowes-Cameron-Cage Test) according to the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, was performed in order to exclude or classify the substance as self-heating substance according to Regulation (EC) No 1272/2008.
In this higher tier study the test item was placed in a cube-form sample container of stainless steel. wire netting (edge length 10 cm, defined mesh size: 0.05 mm) with their top surface open. The oven temperature was adjusted to the test temperature of 140°C.
The submission substance is not placed on the market as a substance, but as a mixture. After manufacturing process it is isolated as a wet presscake exclusively and mixed with different additives to manufacture the traded product. In due consideration of plant, process and product safety, the Bowes-Cameron-Cage Test was carried out with the traded product Sanodure Black CRO containing the submission substance Aluminium Black CRO.
After approximately 10 hours the test item reached the oven temperature of 140°C. Neither spontaneous ignition nor self-heating exceeding the oven temperature of 140°C was observed within 48 hours.
Therefore, the substance has not to be classified as self-heating according to Regulation (EC) No 1272/2008.
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).
