experimental study

Adequacy of study:

key study

Study period:

07 May 2012 to 06 July 2012

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

other: Study performed in accordance with EU test guidelines and in compliance with GLP.

Reason / purpose for cross-reference:

reference to same study

Reason / purpose for cross-reference:

reference to other study

Qualifier:

according to guideline

Guideline:

EU Method A.16 (Relative Self-Ignition Temperature for Solids)

Deviations:

no

GLP compliance:

yes

Key result

Relative self-ignition temperature:

> 220 °C

Remarks on result:

no self-ignition observed up to the melting point

No endothermic or exothermic effect of the test substance was observed between 20°C and 208-220°C (i.e. the melting temperature of the test substance; see sponsor’s information). It demonstrated that the test substance is not self-ignitable.

 

After the experiment, no test substance was left in the test cube or container that was placed below the cube. It indicated that the test substance had evaporated during the experiment.

Conclusions:

Based on the results obtained the test substance is considered ‘not self-ignitable’.

Executive summary:

Study performed in accordance with European Community (EC), EC no. 440/2008, Part A: Methods for the Determination of Physico-Chemical Properties, Guideline A.16: “Relative Self-Ignition Temperature for Solids” and in compliance with the Principles of Good Laboratory Practice (GLP).

 

The self-ignition temperature of 6,6’-di-tert-butyl-4,4’-butylidenedi-m-cresol was determined using a temperature programmed laboratory oven, a stainless steel wire mesh cube, NiCr/NiAl thermocouples and a temperature recording device.

 

Based on the results obtained the test substance is considered ‘not self-ignitable’.

Description of key information

Key value determined by experimental method utilising EU test guidance.

Based on the results obtained the test substance is considered ‘not self-ignitable’.

Additional information
