- Endpoint:
- flash point of flammable liquids
- Data waiving:
- study scientifically not necessary / other information available
- 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

- 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 and/or solids with high melting temperatures. Solids would be tested using appropriate methods to the hazard class and application, where necessary of the flammable solid or combustible solid substance classification criteria. Similarly, for ‘low melting point solids’ 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 (2019) would be subject to testing and application, where necessary of the flammable solid or combustible solid substance classification criteria. 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.

Supporting physico-chemical information for hazard/risk assessment is available and provided to support other endpoints:
EU Method A.9, 1998 : The flash point was determined using EU Method A.9 using the small scale closed cup equilibrium method under GLP. It was noted within the study, that the test item was a ‘low melting point solid’ and therefore proscribed volumes (2 mL or 4 mL) could not be taken. Instead masses were utilised. An aliquot of the test item was transferred to the sample cup of the Setaflash tester. This was 2 g in Setaflash 13740-2 apparatus for temperatures up to 107 °C and/or 4 g for Setaflash 13770-2 apparatus for temperatures above 107°C, respectively. The sample was heated and allowed to equilibrate at the set temperature. The test flame was introduced into the sample cup for approximately 2 seconds by sliding the cup shutter open. Observations were made for ignition of the vapour. If no ignition occurred, the temperature was increased and the test flame re-introduced. This was repeated until the lowest reproducible temperature at which a flash occurred, using a fresh sample, was determined. The results indicated are representative of the replicated (n ≥ 2) lowest temperature at which the test item, measured under the conditions of this study causes the vapour of the liquid to ignite momentarily. Measurements were corrected to 101.325 kPa pressure. The flash point of the test substance has been determined to be 147 ±2 °C at 101.325 kPa.
