Flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2010-03-05 to 2010-03-30
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- other: UN N.1 according to 33.2.1.4 Bundesanstalt für Materialforschung- und prüfung (BAM), Germany
- Deviations:
- no
- GLP compliance:
- no
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Remarks on result:
- substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- Calcium cyanamide, technical grade (Kalkstickstoff) is not flammable in a pre-test according to UN N.1 method.
- Executive summary:
Calcium cyanamide, technical grade (Kalkstickstoff) was tested for flammability according to UN N.1 (33.2.1.4 of BAM). A Brennwertzahl (BWZ) of 1 (max. 6) was determined in the pre-test. The substance only showed glowing combustion for a short time after removal of the flame. Thus, the substance is considered to be non-flammable. No further test is required.
Reference
A Brennwertzahl (BWZ) of 1 (max. 6) was determined in the pre-test. The substance only showed glowing combustion for a short time after removal of the flame. Thus, the substance is considered to be non-flammable. No further test is required.
Description of key information
In the key study Calcium cyanamide, technical grade (Kalkstickstoff) was categorized in category 1 of 6 regarding flammability. Local burning or glowing without further extension. Thus, the substance is not regarded highly flammable. The lower explosive level in a dust explosion test was determined to be 125 g/m³. In addition, no flammability in contact with water and no pyrophoric abilities are expected. These studies are thus been waived.
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
In the key study, Calcium cyanamide, technical grade (Kalkstickstoff) was tested for flammability according to UN N.1 (33.2.1.4 of BAM).
A Brennwertzahl (BWZ) of 1 (max. 6) was determined in the pre-test. The substance only showed glowing combustion for a short time after removal of the flame. Thus, the substance is considered to be non-flammable. No further test is required.
This is supported in a supporting study where the lower explosion limit of a sample of powdered Calcium cyanamide, technical grade (Kalkstickstoff) in air was determined to be 125 g/m3.
Justification for classification or non-classification
Based on the chemical structure, experience on Handling of the substance and the study results taking into account the provisions laid down in Regulation (EC) No 1272/2008, the substance is not considered to be classified as flammable, flammable in contact with water, pyrophoric, self-reactive substance or organic peroxide.
