Any other information on results incl. tables

Assay n°1 :

The test item was left to stay at 140°C ± 2°C during 24 hours.

The edge length of the cubic sample container was 25 mm.

The internal minimal and maximal temperature in the oven was of 140°C (corrected temperature)

The minimum and maximal temperature of the test item was 123°C and 139°C (corrected temperature)

At the start and at the end of the test, the test item was composed of blue powder.

        

Assay ,°2 :

The test item was left to stay at 140°C ± 2°C during 24 hours.

The edge length of the cubic sample container was 100 mm.

The internal minimal and maximal temperature in the oven was of 141°C (corrected temperature)

The minimum and maximal temperature of the test item was 76°C and 140°C (corrected temperature)

At the start and at the end of the test, the test item was composed of blue powder.

--> No self-heating of the test item was recorded in both assay.

 

 

 

Applicant's summary and conclusion

Conclusions:
No self ignition of the test item was recorded.
The result is considered negative, the test item was not classified in division 4.2.

Executive summary:

The test was performed according to the united Nations Recommendations on the Transport of Dangerous Goods Manual of tests and Criteria Sixth revised edition (2015) Test N.4 (Part III, Section 33.3.1.6) EC No. 1272/2008 (CLP).

No self ignition of the test item was recorded, therefore, the test item was not classified in Division 4.2 and was not assigned to any packing group, under the experimental conditions used.

According to EC No. 1272/2008 (CLP), the test item was not classified.
