Applicant's summary and conclusion
- Conclusions:
- The study was performed according to EU method A.2 with acceptable restrictions (no GLP) and therefore reliability of Klimisch 2 has been assigned. No boiling point could be detected up to a temperature of 300 °C.
- Executive summary:
The boiling point of the test substance has been determined in a non-GLP test according to EU method A.2 using the DSC method. The DSC technique records the difference in energy inputs into a substance and a reference material as a function of temperature, while the substance and reference material are subjected to the same controlled temperature programme. This energy is the energy necessary to establish zero temperature difference between the substance and the reference material. When the sample undergoes a transition involving a change of enthalpy, that change is indicated by an endothermic departure (boiling) from the base line of the heat flow record. The barometric pressure at the time of the test runs was 1008 - 1009 hPa. No boiling point could be detected up to a temperature of 300 °C; the boiling temperature of 1,8-Dichlorantrachinon is specified > 300 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
