- key study
- Study period:
- April 1988
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- Deviations:
- yes
- Remarks:
- slightly different test methods
- Principles of method if other than guideline:
- The principles of the test methods including their deviations to the guideline are described in detail in the field "any other information on materials and methods".
- GLP compliance:
- not specified
- Key result
- Test procedure:
- burning time (test type not further specified)
- Moisture (wt %):
- 20
- 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:
- GHS criteria not met
- Conclusions:
- Nitroguanidine is considered to be not highly flammable.
- Executive summary:
The tests were conducted according to guidelines similar to guideline A.10.
The nitroguanidine moistened with 20% water was dried before testing. The dried nitroguanidine could not be ignited by the 1000 °C hot platin wire, which was dipped for 5 seconds into the substance.
In a second test approx. 200 mg of nitroguanidine were put into a flat iron bowl and heated with an open gas flame burner for 10-15 seconds. No ignition of nitroguanidine was observed.
In a third test nitroguanidine and a 1:1 mixture of nitroguanidine with potassium nitrate was put into a red heated iron bowl for 60 seconds and was scorched shortly scorched quickly extinguished.
Therefore it is concluded that nitroguanidine is not highly flammable.
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- September 1997 - March 1998
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- 1. The testing apparature consists of a bunsen burner and a heat resistant tile. The flame of the bunsen burner (approx 20 mm high and 5 mm wide) heats a pile of test substance for 10 seconds by the flame of the bunsen burner. The test is conducted five times.
2. The testing apparatur consists of a hemispherical bowl (inner diameter 120 mm), wall thickness 1 mm and a teclu burner (19 mm diameter). Approx. 5 ml or in care of very explosive substances even less of the test substance are put into the red heated iron bowl (approx. 700 °C). It is reported if the test substance ignites immediately or at what retardation time, how long the substances is burning, if the burning is increased with more substance and if there is a residue. The test is conducted three times; the shortest burning time is recorded in the tables, if relevant. - GLP compliance:
- not specified
- Specific details on test material used for the study:
- Test substance supplier not specified
- Test procedure:
- burning time (test type not further specified)
- Moisture (wt %):
- 0
- 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:
- GHS criteria not met
- Conclusions:
- Nitroguanidine is considered to be not highly flammable
- Executive summary:
The tests were conducted according to a method developed by the Federal German Instute for Material Testing (BAM). Although there is no information available with regard to substance purity it is assumed that the authors - members of the German Institute for Material Testing - used adequate substances to obtain representative results. Therefore the test results are assumed to be valid.
Approx. 5 ml of nitroguanidine were put onto a heat resistant tile and heated with an open gas flame burner for 10 seconds. the substance was ignited but distinguished afterwards.
In a second test 5 ml nitroguanidine were put into a red heated hemsipheric iron bowl (approx. 700 °C). The burning time was observed to be 8 seconds.
Therefore it is concluded that nitroguanidine is not highly flammable.
Referenceopen allclose all
Nitroguanidine could not be ignited by the 1000 °C hot platin wire, which was dipped for 5 seconds into the dried substance but Nitroguanidine is melting by generating smoke emissions.
Nitroguanidine could not be ignited by a open gas flame held onto the substance for approx. 10-15 seconds but nitroguanidine is melting by generating smoke emissions and changes its colour into yellow.
Nitroguanidine scorched shortly and extinguished quickly when put into a red heated iron bowl for 60 seconds but nitroguanidine is melting and evaporates in the pure test. In the mixture with potassium nitrate an explosive flame occurs.

Description of key information
There are two studies available.
The key study was conducted according to a method similar to guideline A.10 whereas the supporting study was conducted according to a method developed by the German Federal Institute for Material Testing (BAM) which is also similar to guideline A.10. In both studies nitroguanidine is considered to be not highly flammable.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
There are two studies available. The key study was conducted according to a method very similar to guideline A.10. Allthough both studies indicate the same results the key study was chosen because of the more detailed description of the test material.
Nitroguanidine moistened with 20% water was dried before testing. The dried nitroguanidine could not be ignited by the 1000 °C hot platin wire, which was dipped for 5 seconds into the substance.
In a second test approx. 200 mg of nitroguanidine were put into a flat iron bowl and heated with an open gas flame burner for 10-15 seconds. No ignition of nitroguanidine was observed.
In a third test nitroguanidine and a 1:1 mixture of nitroguanidine with potassium nitrate was put into a red heated iron bowl for 60 seconds. Nitroguanidine was scorched and extinguished in short time.
The supporting study was conducted from the German Federal Institute for Material Testing (BAM) according to methods from BAM. There are two tests available which are very similar to test no 2 and 3 of the key study. Although the supporting study has slightly other testing conditions (e.g. significantly less material used) its results are in line with the those of the key study.
Therefore it is concluded that nitroguanidine is not highly flammable.
Justification for classification or non-classification
Nitroguanidine does not ignite under the test conditions.
Therefore it is concluded that nitroguanidine is not highly flammable.
