Description of key information

Self-ignition is not considered to be of relevance for barium carbonate, since this would require heat to be developed either by reaction of this substance with oxygen or by exothermic decomposition and which is not lost rapidly enough to the surroundings (in accordance with section 1 of REACH Annex XI). Since barium carbonate represents the highest oxidised form of barium it is intrinsically not combustible and can safely be assumed not to be ignitable under the conditions given Test N4 Part III, sub-section of the “UN Recommendations on the Transport of Dangerous Good, Manual of Tests and Criteria”. In conclusion, the conduct of further experimental verification is not considered to be required.
