Additional information

Column 2 of REACH Annex VII section 7.5 states that the vapour pressure measurement "does not need to be conducted if the melting point is above 300°C." These substances are considered to have a very low vapour pressure. The melting point of tin disulfide was determined experimentally according to EU method A.1 and OECD 102 to be >515°C. For the risk assessment a worst case value of 0.000000001 Pa (the lowest value which could be added to the relevant field in the endpoint summary) will be used.
