Reference
Endpoint:
relative self-ignition temperature (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:
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
Deviations:
no
GLP compliance:
yes
Key result
Relative self-ignition temperature:
326 °C
Remarks on result:
other: relative spontaneous ignition temperature, undergoing spontaneous combustion

Pressure not reported.

Conclusions:
No self ignition temperature could be determined, because tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate undergoes spontaneous combustion.
Executive summary:

According to EU method A.16 no self ignition temperature of tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate could be determined because it undergoes spontaneous combustion. The relative spontaneous ignition temperature is 326°C.

Description of key information

Following the EU method A.16, no self ignition temperature could be determined, because tetrasodium hydrogen 2-phosphonatobutane-1,2,4-tricarboxylate undergoes spontaneous combustion.

Key value for chemical safety assessment
