Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Link to relevant study record(s)
- Endpoint:
- explosiveness, other
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 2014
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Results of tests performed with the test item are compared with results of the same tests obtained with tetrafluoroethlene (well-studied explosive monomer).
The assessment of test item explosive decomposition is then assess based on this comparison. - GLP compliance:
- no
- Interpretation of results:
- study cannot be used for classification
- Executive summary:
Test item explosive decomposition was assess thanks to a well studied explosive monomer: tetrafluoroethlene.
Experimental tests have been performed on the test item and this reference substance. The explosive properties of the test item were determined by comparison of the results obtained on these both substances.
The experimental results show that the explosive properties of the test item are somewhat different from those of tetrafluoroethylene (TFE), although they are close to them.
Based on the results obtained, it was possible to conclude that test item is more dangerously explosive that TFE, even if insignificantly. Both of the monomers are almost nondetonable in liquid phase.
- Endpoint:
- explosive properties of explosives
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance is a gas
Referenceopen allclose all
The experimental results show that the explosive properties of the test item are somewhat different from those of tetrafluoroethylene (TFE), although they are close to them.
A maximum increase in the pressure upon the explosion of test item is significantly higher (by a factor of approximately 1.5). The rate of test item combustion (the reciprocal time of a pressure increase on confined explosion) is higher by approximately 15%. The minimum energy of test item ignition is lower; for example, at a pressure of 2.5 atm, a discharge with a source energy of 11 J ignites test item but it does not ignite TFE. As for the possibility of transition of combustion from a gas phase to a liquid, which was observed on TFE, an additional study should be performed over a wider range of conditions in order to detect it in test item. Thus it is possible to draw the conclusion that test item is more dangerously explosive that TFE, even if insignificantly. Both of the monomers are almost nondetonable in liquid phase.
Description of key information
Due to the test item physical state (gas), an experimental test is not required for REACH registration.
