Applicant's summary and conclusion

Conclusions:
No self heating was observed.
Executive summary:

The self-ignition of Chloranil (2,3,5,6-tetrachloro-1,4-benzoquinone) was tested in the Grewer oven (wire basket of 8 cm³ volume) with the substance as delivered as well as in the mixture with an inert material (Kieselgur, ratio 1:1 by mass). In both cases no self heating was observed.
