Link to relevant study record(s)
- Endpoint:
- explosive properties of explosives
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 23 November 1995
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- Limitations in the reporting of experimental details. The main study was not performed as the result from the preliminary study was sufficient to determine the explosive properties of the substance.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.14 (Explosive properties)
- Version / remarks:
- 1992
- Deviations:
- not specified
- GLP compliance:
- not specified
- Key result
- Parameter:
- thermal sensitivity - Koenen test: diameter of the orifice plate
- Value:
- 2
- Number of fragments:
- 6
- Remarks on result:
- positive (not further specified)
- Interpretation of results:
- unstable explosive based on GHS criteria
- Conclusions:
- The test substance in powder form exhibited a positive response in the preliminary test for thermal sensitivity.
- Executive summary:
The explosive properties of the test substance were determined according to EU Method A.14 (1992). The test substance was tested as a white crystalline powder, at a loading of 35.4 g. During the preliminary test, the steel tube was unchanged using an orifice plate with a 6 mm hole. Upon installing the orifice plate with a 2 mm hole, an explosion occurred, resulting in six fragments. This is regarded as a positive result in the partial test for thermal sensitivity. This study is considered to be reliable with restriction (Klimisch 2) as there are limitations in the reporting of experimental conditions.

Additional information
The explosive properties of the test substance were determined according to EU Method A.14 (1992) (Vill 1995). The test substance was tested as a white crystalline powder, at a loading of 35.4 g. During the preliminary test, the steel tube was unchanged using an orifice plate with a 6 mm hole. Upon installing the orifice plate with a 2 mm hole, an explosion occurred, resulting in six fragments. This is regarded as a positive result in the partial test for thermal sensitivity. This study is considered to be reliable with restriction (Klimisch 2) as there are limitations in the reporting of experimental conditions.
A series of studies were also carried out to investigate the self-reactive properties of the test substance in aqueous solution. The classification of an approximately 10% solution of the test material in water (Pt content up to 5.4%) was determined using the flow scheme for class 4.1 of the Dangerous Goods Regulation for self-reactive substances (Wildner et al. 1996). The following tests were performed: ability to propagate a detonation (UN Test A1), deflagration capability (UN Tests C.1 and C.2), effect on heating under defined inclusion (UN Tests E.1 and E.2), explosive effect (UN Test F.3) and thermal stability (UN Test H.4). The test solution was not able to propagate a detonation, was not able to deflagrate, had no effect on heating under defined inclusion, had no explosive effect and was thermally stable (SADT > 55°C for a 50kg package). The test material in a 10% water solution is therefore excluded as a type G substance for the requirements of class 4.1, self-reactive substances according to the Dangerous Goods Regulations. This study is considered to be reliable with restrictions (Klimisch 2) as the raw data were not available for review.
Due to the explosive properties of the test substance when dry, this substance must be kept in aqueous solution <= 10 % w/w and is only marketed as such.
Justification for classification or non-classification
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
