Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
test procedure in accordance with national standard methods with acceptable restrictions
Qualifier:
according to
Guideline:
other: German standard "VDI 2263, Part 1 ‘Test Methods for the Determination of the Safety Characteristic of Dusts’
GLP compliance:
no
Other quality assurance:
ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
Specific details on test material used for the study:
- Purity not specified
- Batch number: BXR5U4G
Key result
Test procedure:
other: heated up to 410 °C at a rate of 0.5 K/min, air flow of about 20 L/h
Max. temp. reached:
410
Induction time (h):
12
Result:
negative outcome (no effect observed)
Remarks:
No exothermic effects were determined up to the point at which the test substance melted. The wire mesh basket was empty after the measurement.
Remarks on result:
other: The sample in its delivery state was tested
Interpretation of results:
not classified based on GHS criteria
Conclusions:
Imidoxim is not a self-heating substance in the sense of CLP Annex I, 2.11. The determination according to UN-MTC Procedure N.4 (Bowes-Cameron-Cage-Test) is not necessary.
Executive summary:

Imidoxim is not a self-heating substance in the sense of CLP Annex I, 2.11. The determination according to UN-MTC Procedure N.4 (Bowes-Cameron-Cage-Test) is not necessary.

Endpoint:
substances / mixtures which in contact with water emit flammable gases
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2000
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
test procedure in accordance with national standard methods with acceptable restrictions
Qualifier:
according to
Guideline:
EU Method A.12 (Flammability (Contact with Water))
GLP compliance:
yes

Imidoxim does not liberate gases in hazardous amounts when tested according to EU method A.12.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
Imidoxim does not emit flammable gases on contact with water.
Executive summary:

The flammability of Imidoxim was determined following the method A.12 (EU-method). The test item did not emit flammable gases on contact with water in hazardous amounts. Therefore Imidoxim is classified as non flammable.

Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2000
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
test procedure in accordance with national standard methods with acceptable restrictions
Qualifier:
according to
Guideline:
EU Method A.10 (Flammability (Solids))
GLP compliance:
yes
Other quality assurance:

Imidoxim melted when approached by the ignition flame and was extinguished within the start segment.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
Imidoxim is classified as not highly flammable.
Executive summary:

The flammability of Imidoxim was determined following the method A.10 (EU-method). The test item melted when approached by the ignition flame and was extinguished within the start segment. Therefore Imidoxim is classified as not highly flammable.

Endpoint:
flammable solids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

Description of key information

Flammability: Imidoxim is classified as not highly flammable. 

Flammability in contact with water: Imidoxim does not emit flammable gases on contact with water.

Pyrophoric properties: Imidoxim did not deliver indications of pyrophoric properties during the realization of other tests. The determination according to UN test procedure ‘Recommendations on the Transport of Dangerous Goods - Manual of Tests and Criteria’ (UN-MTC) Procedure N.2 is not necessary. Imidoxim has no pyrophoric properties and is in the sense of the CLP-Directive a non-pyrophoric solid.

Self-heating properties: Imidoxim is not a self-heating substance in the sense of CLP Annex I, 2.11. The determination according to UN-MTC Procedure N.4 (Bowes-Cameron-Cage-Test) is not necessary.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Justification for classification or non-classification

Based on data mentioned above, Imidoxim is not classified as flammable, self-heating or pyrophoric. It does not emit flammable gases on contact with water.
