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.

Experience in production or handling; tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate is known to be stable at room temperature.

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.

Remarks:
corresponding to 'no' in migrated source record.| Remarks:does not emit flammable gases in contact with water | Additional remarks: Tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate did not ignite spontaneously with water and did not liberate gases in hazardous amounts.

Tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate does not emit flammable gases in contact with water.

Interpretation of results:
non flammable
Conclusions:
Tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate does not emit flammable gases in contact with water.
Executive summary:

Tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate does not emit flammable gases in contact with water when tested according to EC Test Procedure A 12. It also did not ignite spontaneously with water and did not liberate gases in hazardous amounts.

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.

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

Justification for classification or non-classification

Tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate is not flammable, it has no pyrophoric properties, and no flammability in contact with water; and hence no classification according to both Directive 67/548/EEC and GHS (Regulation EC 1272/2008).
