Flash point

Link to relevant study record(s)

Reference

Endpoint:

flash point of flammable liquids

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the flash point is only relevant to liquids and low melting point solids

the study does not need to be conducted because decomposition occurred during the melting point study

other:

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING
In accordance with Section 2 of REACH Regulation (EC) No. 1907/2006: Annex XI, the study of flash-point does not need to be completed, based on the physical state of the substance. According to Regulation (EC) No. 440/2008 as amended EU Method A.9: Flash-Point is only applicable to liquids at room temperature. Therefore the method, has limited to no applicability to solids with high melting temperatures. At temperatures close to the melting-point the test item should behave similarly to ‘pasty-substances’ which under Regulation (EC) 1272/2008 as amended and the UN Transport of Dangerous Goods Manual of Tests and Criteria (2015) would be tested and application, where necessary of the flammable solid or combustible solid substance classification criteria. Furthermore, in accordance with REACH Regulation (EC) No. 1907/2006 Annex VII, column 2 section 7.9, the estimated flash point would exceed 200 °C and this based on available information consisting of: preliminary TGA and DSC measurements for Melting Point in accordance with OECD TG 102, the substance was observed to decompose at ca. 237 °C (510K) prior to melting. Therefore the terminology of the flash-point has no relevance to the substance. According to ECHA Guidance on Information Requirements and Chemical Safety Assessment (Chapter R.7a: Endpoint Specific Guidance, R.7.1.9 and R.7.1.10.3, July 2017) and ECHA Guidance on Application of the CLP Criteria (version 5.0, July 2017) the study does not need to be conducted.

Description of key information

Flash-Point: Inapplicable to the substance, based on physical state at room temperature and decomposition prior to melting at > 200 °C, 2018
