- the results of flash point measurements according to ISO 3679 and ISO standards are: for HCFO-1233zd Z: 40 ° C at atmospheric pressure, and for HCFO-1233zd E: 18 ° C at atmospheric pressure.
- compositions are measured according to IEC 61620.
- the following compositions are prepared by mixing at room temperature and Jarylec ® C101 atmospheric pressure and HCFO-1233zd Z, both in liquid form.
- Table 4 The results of Table 4 above show that the addition of a halogenated hydrocarbon, even in small quantity, in a dielectric fluid makes it possible to make the flash point undetectable, under the test conditions, which corresponds to a non-flammable composition. Moreover, the addition of a halogenated hydrocarbon, even in a small amount, in a dielectric fluid does not lead to a decrease in the permittivity of the composition, but on the contrary makes it possible to increase the permittivity of said composition, by comparison with the permittivity of the dielectric fluid alone.
