Link to relevant study record(s)
- Endpoint:
- explosiveness, other
- Type of information:
- other: based on expert judgement
- Adequacy of study:
- key study
- Study period:
- 04 January 2006
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The expert judgement based on the UN Recommendations on the Transport of Dangerous Goods (Manual of Tests and Criteria, Annex 6, Orange Book, 3rd edition, 1999).
- GLP compliance:
- no
- Specific details on test material used for the study:
- Identity: FAT 40824/A
Batch: Red ROE 805 BOP 04/05
Appearance: dark red powder
Purity: Organic part (Na-salt): approx. 82 %; Main component 1: approx. 36.2 %; Main component 2: approx. 27.5 %; Oligomers: 10 %
Expiration date: 01 October 2010
Storage: At room temperature at about 20 °C in a desiccator (hygroscopic) - Parameter:
- other: based on reactive groups, oxygen balance and exothermic decomposition energy
- Remarks on result:
- negative (not further specified)
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based on the chemical structure and assessment of calorimetric behaviour during heating to 500 °C, FAT 40824/A is not to be classified as explosive.
- Executive summary:
The explosive properties of FAT 40824/A were estimated based on the UN Recommendations on the Transport of Dangerous Goods (Manual of Tests and Criteria, Annex 6, Orange Book, 3rd edition, 1999) where a set of criteria is compiled to identify materials being potential explosives. The exothermic decomposition energy was determined using Differential Scanning Calorimetry in a closed, gold plated high pressure vessel (DSC). The calorimetric test is of special importance for the evaluation of compounds containing chemical groups associated with explosive properties (here azo function). The total decomposition energy (Delta H dec determined between room temperature and 500 °C) was found to be about 293 J/g thus being far below the UN limit of 500 J/g. Two exothermic peaks have been found. The onset point of the first peak was at about 173 °C. Thus, the substance is non explosive. Based on the chemical structure and assessment of calorimetric behaviour during heating to 500 °C, FAT 40824/A is not to be classified as explosive.
Reference
The total decomposition energy (Δ HDec determined between room temperature and 500 °C) was found to be about 293 J/g thus being far below the UN limit of 500 J/g. Two exothermic peaks have been found. The onset point of the first peak was at about 173 °C. Based on the chemical structure, FAT 40824/A is not to be classified as explosive material and no experimental determination according to the EC test guideline A.14 has to be performed. The presence of an azo group seems to pose no risk as demonstrated by the calorimetric test. The result of item 2 (oxygen balance) is not considered relevant for this substance as the substance is not adequately characterised by taking into account carbon, hydrogen and oxygen only and omitting nitrogen, sulphur and chlorine. Thus, it can be concluded beyond a reasonable doubt, that FAT 40824/A is not a potential explosive and does not have a potential for rapid energy release. Nevertheless, this judgement is in respect to classification; it does not necessarily mean that any processing hazards can be discounted.

Justification for classification or non-classification
The test substance has been considered to be non-explosive based on the expert statement, hence does not warrant classification according to the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
