According transport classification, the product has to be classified as UN3088 4.2 GE III. So for CLP, it should be classified as Self Heating Cat.2, H252.

Report extract (key results) :

Porte échantillon	Température de consigne	Conclusion
100mm	140°C	positif
25mm	140°C	négatif
100mm	120°C	positif
100mm	100°C	positif

The product is classified as cat. 2 because :

- positive result for 100mm, 140°C and

- negative result for 25mm, 140°C and

- positive result for 100mm, 100°C

Conclusions:

According transport classification, the product has to be classified as UN3088 4.2 GE III. So for CLP, it should be classified as Self Heating Cat.2, H252.

Remarks:

at atm. press. of ca.1013.0 mBar

An exothermic reaction was observed during the test for three assays, the duration of exothermic reaction varied between 55 an 58 min. A self ignition reaction was observed during the test for two out of three assays. The maximum temperature reached by the test item was situated between 546 and 606°C.

In the study no atmospheric pressure was stated at which the self-ignition temperature was measured. Because of this it was assumed that the self-ignition temperature was measured at ca. 1013 mBar.

Conclusions:

The self-ignition temperature of the test item was situated between 340 and 359°C (corrected value).

Description of key information

The self-ignition temperature of resin acids and rosin acids, cobalt salts was situated between 340 and 359°C (corrected value).

Self heating proprieties were evaluating by test done according guideline ONU N4.

The product should be classified as self heating cat2, H252.
