EC number: 948-652-3 | CAS number: -
The relative self-ignition temparute of the test item Slimes and sludges, electrolytic tin refining was tested according to
- Recommendations on the TRANSPORT OF DANGEROUS GOODS: Manual of Tests and Criteria, 6th edition, New York and Geneva, 2015: Appendix 6 Screening Procedures, Division 4.2: Substances which may be liable to spontaneous combustion
-VDI 2263 (1990), sheet 1, Grewer Oven
In the investigation of self-heating in the Grewer Oven for the pure test item initially an endothermic effect was detected in the temperature range of 40 -120°C. An exothermic effect was detected starting at 200°C, which led to a maximum temperature of 340°C.
The pure test item Slimes and sludges, electrolytic tin refining indicated a self-heating at atmospheric pressure starting at a temperature of approx. 200°C, which leaded to a maximum temperature of 340°C. On the basis of the results of the screening test on the self-heating in the Grewer Oven a classisifcation of the test item as self-heating substance cannot be excluded.
The pure test item 'Slimes and sludges electrolytic refining of tin, lead and silver containing alloy' (formerly called Slimes and sludges, electrolytic tin refining) indicated a self-heating at atmospheric pressure starting at a temperature of approx. 200°C, which lead to a maximum temperature of 340°C.
On the basis of the results of the screening test on the self-heating in the Grewer Oven a classisifcation of the test item as self-heating substance cannot be excluded. Based on a precautionary principle, the substance is classified as Flammable solid Cat. 1 (H228) and Self Heating Cat. 1 (H251).
