self-heating substances / mixtures

Type of information:

experimental study

Adequacy of study:

key study

Study period:

01 March 2017 - 05 May 2017

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

UN Manual of Tests and Criteria: Test N.4 (Test method for self-heating substances)

Version / remarks:

Rev. 6 (2015)

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Specific details on test material used for the study:

decomposition temp.: 175°C

Key result

Test procedure:

100 mm sample cube at 140°C

Result:

negative outcome (no effect observed)

An exothermic effect of the test item by self-heating was observed at an oven temperature of 142°C. During this effect the test item reached a temperature of 152°C. According to the guideline, the test is positive when the sample temperature exceeds the oven temperature by 60°C during the 24 hour testing time. Based on this, the result is considered negative and it demonstrated that the test item is “not a self-heating substance”.

After the experiment, the test item had turned into a darker pink residue. The change of colour might be due to decomposition/reaction.

 

Interpretation of results:

other: not classified based on GHS or CLP criteria

Conclusions:

The substance is not self-heating.

Executive summary:

In a GLP study according to UN Test N.4, a negative result was obtained using a 10 cm sample cube at 140°C. From this it was concluded that C.I. Pigment Red 81:2 is not a self-heating substance.
