Description of key information

From the experimental data obtained according to A.14 method in Council Regulation (EC) No 440/2008 of 30 May 2008, it can be concluded that the 4-Chloro-α,α,α-trifluorotoluene (PCBTF) sample did not present explosive properties.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Thermal sensitivity (effect of flame)

 None of the six tests (three of them with theorifice plate and the remaining with theorifice plate) gave rise to explosion or breaking of any tube. 

In the three tests with theorifice plate the following phenomena were observed:

a flame generation began in the test chamber after about 28 seconds with a formation of black dense smoke with unpleasant odour and enlargement of the flame; after about 94 seconds all phenomena ended.

In the three tests with theorifice plate similar phenomena toorifice plate were observed.

The test result is considered negative.

  

Mechanical sensitivity (effect of shock)

 No explosion was obtained during the series of six tests at 40 J performed on the test item (bursting into flame and/or a report is equivalent to explosion).

The test result is considered negative.
