- Conclusions:
- From the experimental data obtained, it can be concluded that the sample of Sodium metabisulphite does not exhibit explosive properties, according to the guideline in Official Journal L 283 A.14.
- Executive summary:
The explosive properties of Sodium metabisulphide were determined in test conducted according to guideline.
Three tests were carried out: a) Thermal sensitivity - effect of flame, b) Mechanical sensitivity - effect of shock and c) Mechanical sensitivity - effect of friction). From the experimental data obtained, it can be concluded that the sample of Sodium metabisulphite does not exhibit explosive properties, according to the guideline in Official Journal L 283 A.14.
Reference
Thermal sensitivity - effect of flame: None of the six tests (three of them with the 6 mm orifice plate and the remaining with the 2 mm orifice plate) gave rise to explosion or breaking of any tube. In the three tests with the 6 mm orifice plate the following phenomena were observed: a combustion with a flame generation began in the test chamber after 120 seconds; the combustion phenomena persisted until 282 seconds without any fragmentation of the tube. In the three tests with the 2 mm orifice plate similar phenomena to 6 mm orifice plate phenomena were observed: a combustion with a flame generation began in the test chamber after 120 seconds; the combustion phenomena persisted until 282 seconds without any fragmentation of the tube.
Mechanical sensitivity - effect of shock: During the test, the test item did not explode or break down until a 90 J impact energy. The test item was less sensitive than the reference substance.
Mechanical sensitivity - effect of friction: During the six tests the test item did not explode with the 360 N energy load applied.
Description of key information
Explosive properties of sodium metabisulphite (experimental results, according to the guideline in Official Journal L 283 A.14.): Disodium disulfite does not exhibit explosive properties.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
One study report is available. The study was conducted according to GLP standards. The explosive properties of sodium metabisulphite was determined according to EU guideline method.
Preliminary tests were carried out to establish safe conditions for the performance of the 3 tests (a) Thermal sensitivity - effect of flame, b) Mechanical sensitivity - effect of shock and c) Mechanical sensitivity - effect of friction). From the experimental data obtained, it can be concluded that the sample of Sodium metabisulphite does not exhibit explosive properties, according to the guideline in Official Journal L 283 A.14.
Justification for classification or non-classification
The explosiveness of disodium disulfite was determined according to EU guideline A.14. Based on experimental results, disodium disulfite does not need to be classified according to Regulation (EC) No. 1272/2008 (CLP Regulation).
