Specific details on test material used for the study:
- Charge-No: CH 120721

The test substance melted when approached by the ignition flame.

The substance did not burn down or burn up.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The substance 1,8-naphthylenediamine did not burn down or burn up.
Executive summary:

1,8-naphthylenediamine melted when approached by the ignition flame (in accordance with the guideline UN N.1) and did not burn down or burn up, indicating that 1,8-naphthylenediamine is not flammable (Bayer Technology Services, 2013).

Description of key information

A) Flammability: not flammable solid
Remark: The test substance melted when approached by the ignition flame and did not burn down or burn up.
B) Contact with water: In accordance with section 1 of REACH Annex XI, the study on flammability in contact with water does not need to be conducted as the substance contains no metals or metalloids and there-fore will not release flammable gases in contact with water.
C) Pyrophoric properties: 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 and the structure does not give a reference to pyrophoric properties.

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

Justification for classification or non-classification

The substance is not readily combustible, has no pyrophoric property, and shows no flammability in contact with water; and hence no classification according to Regulation (EC) 1272/2008 (CLP).
