Reference

Endpoint:

relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

04 February 1999

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

other: United Nations, Recommendations on the transport of Dangerous Goods, Manual of Tests and Criteria; Part Ill, Section 33, Test N.4: "Test method for self-heating substances" (United Nations; New York and Geneva, Second revised edition 1995).

Principles of method if other than guideline:

- Principle of test: The purpose of the test was to determine whether a substance is able to reach a temperature of 200°C by self-heating under specified storage conditions.

- Short description of test conditions: The containers were placed in the centre of the oven. The oven temperature was raised to 140°C and kept there for 24 hours.
The temperatures of the samples and the oven were recorded in time intervals of 30 minutes.

- Parameters analysed / observed:Observations were made to determine whether the test substance reaches a temperature of 200°C by self-heating.
At the end of the test, the consistency of the test substance was determined

GLP compliance:

yes

Key result

Relative self-ignition temperature:

> 140 °C

Remarks on result:

no self ignition observed under the test conditions

Conclusions:

In the test where the container with dimensions 10 cm x 10 cm x 10 cm was used, no significant temperature rise was observed. After the test, no changes were observed in the appearance of the test substance. The sample temperature did not exceed 200°C. Therefore, the substance should not be classified in Division 4.2 (according to the criteria as described in the recommendation).
In conclusion, C.I.PIGMENT RED 81:5 - C.1.45160:4 should not be classified in Division 4.2; Packing Group Ill.

Description of key information
