- Executive summary:
The investigation of calcium carbide according to the method A.14 "explosive properties", annex to Commission Directive 92/69/EEC of 31 July 1992 (Official Journal of the European Communities L 383 A of 29 December 1992) was carried out in compliance with the principles of the Good Laboratory Practice (GLP).
The test substance was neither sensitive to heat, shock, nor friction.
The substance, based on the test results, is not an explosive in the sense of the criteria of the method A.14 "explosive properties", annex to Commission Directive 92/69/EEC.
Reference
Thermal sensitivity (Koenen test)
Testing according to the standard operating procedure "StAA-Nr. 11/15.01 ". Result: It turned out, that the substance was not thermally sensitive when heated under defined confinement (diameter of the orifice 2.0 mm). Further tests at 6,0 mm were not performed
because based on experience an explosion at 6,0 mm diameter of the orifice plate was not expected.
Mechanical sensitivity (shock, BAM Fallhammer))
Testing according to the standard operating procedure "StAA-Nr. 11/1 5.02" at impact energies of 40 J (drop weight 10 kg, fall height 40 cm).
Result: It turned out, that the substance was not sensitive at 40 J.
Mechanical sensitivity (friction, BAM friction apparatus)
Testing according to the standard operating procedure "StAA-Nr. 11/1 5.03" with a 360 N loading.
Result: It turned out, that the substance was not sensitive under a loading of 360 N.
Description of key information
The test substance calcium carbide is non explosive
(thermal sensitivity, shock, friction) in accordance with method EU A.14.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
The investigation of calcium carbide according to the method A.14 "explosive properties", annex to Commission Directive 92/69/EEC of 31 July 1992 (Official Journal of the European Communities L 383 A of 29 December 1992) was carried out in compliance with the principles of the Good Laboratory Practice (GLP).
The test substance was neither sensitive to heat, shock, nor friction.
The substance, based on the test results, is not an explosive in the sense of the criteria of the method A.14 "explosive properties", annex to Commission Directive 92/69/EEC.
Justification for classification or non-classification
Based on guideline study calcium acetylide does not need to be classified as explosive
