Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study without detailed documentation
- Qualifier:
- according to guideline
- Guideline:
- other: UN N.1
- Principles of method if other than guideline:
- Test method for readily combustible solids.
- GLP compliance:
- no
- Executive summary:
The test substance melted when approached by the ignition flame. Upon removal of the ignition source the reaction extinguished immediately (method: UN N.1).
In accordance with section 1 of REACH Annex XI, the studies on pyrophoric property and flammability in contact with water do not need to be conducted as:
(a) No flammability in contact with water: The chemical structure of the substance does not contain metals or metalloids.
(b) Phyrophoric property: Experience in production or handling shows that the substance does not ignite spontaneously on coming into contact with air at normal temperatures (i.e. the substance is known to be stable at room temperature for prolonged periods of time).
(Currenta, 2009)
Reference

Description of key information
Testing the flammability according to the UN N1 method, the substance melted when approached by the ignition flame. Upon removal of the ignition source the reaction extinguished immediately, (Currenta 2009). Therefore phthalic anhydride can be classified as a non flammable solid.
In accordance with section 1 of REACH Annex XI, the studies on pyrophoric property and flammability in contact with water do not need to be conducted as:
(a) No flammability in contact with water: The chemical structure of the substance does not contain metals or metalloids.
(b) Phyrophoric property: Experience in production or handling shows that the substance does not ignite spontaneously on coming into contact with air at normal temperatures (i.e. the substance is known to be stable at room temperature for prolonged periods of time).

Additional information
Justification for classification or non-classification
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
