Link to relevant study record(s)
- Endpoint:
- pyrophoric solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2012
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- other: UN N.1
- Deviations:
- no
- GLP compliance:
- yes
- Test procedure:
- ignition time on contact with air
- Remarks on result:
- no ignition on contact with air (not further specified)
- Remarks:
- corresponding to 'no' in migrated source record. | Remarks: | Additional remarks: tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate did not burn down or burn up.
- Interpretation of results:
- non flammable
- Conclusions:
- Tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate did not burn down or burn up.
- Executive summary:
The flammability of tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate is determined following the methods N.1 (UN-manual of testing). The test substance did not burn up or down. Therefore tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate is classified as a non flammable solid.
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study

- Rationale for reliability incl. deficiencies:
- other: Expert judgement
- Principles of method if other than guideline:
- Expert statement
- GLP compliance:
- yes
- Interpretation of results:
- other: no pyrophoric properties
- Conclusions:
- Experience in production or handling; tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate is known to be stable at room temperature.
- Executive summary:
Pyrophoric properties are determined following the methods N.2 (UN-Manual of testing) or A.13 (EU-method). However, in accordance with section 1 of REACH Annex XI, a study does not need to be conducted as it is scientifically unjustified. Based on experience during handling and use, no pyrophoric properties were observed; tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate is known to be stable at room temperature.

Referenceopen allclose all
Experience in production or handling; tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate is known to be stable at room temperature.
Tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate does not emit flammable gases in contact with water.
Description of key information
A) Flammability: not flammable solid
Tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate did not burn down or burn up when tested according to UN N.1.
B) Contact with water: does not emit flammable gases in contact with water
Tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate did not ignite spontaneously with water and did not liberate gases in hazardous amounts when tested according to EC Test Procedure A 12 (UN N.5).
C) Pyrophoric properties: no pyrophoric properties
Pyrophoric properties are determined following the methods N.2 (UN-Manual of testing) or A.13 (EU-method). However, in accordance with section 1 of REACH Annex XI, a study does not need to be conducted as it is scientifically unjustified. Based on experience during handling and use, no pyrophoric properties were observed; substance is known to be stable at room temperature.
