The substance in its delivery state was measured. The test substance melted when approached by the ignition flame. The substance did not burn up. No further testing was required.

Interpretation of results:
non flammable
Conclusions:
17 alpha-Cyanomethyl-17 beta-hydroxy-5(10)-estren-3-one is in the sense of the CLP-Guideline a non-flammable solid.
Executive summary:

17 alpha-Cyanomethyl-17 beta-hydroxy-5(10)-estren-3-one in its delivery state melted when approached by the ignition flame. The substance did not burn up. Therefore 17 alpha-Cyanomethyl-17 beta-hydroxy-5(10)-estren-3-one is classified as a not readily combustible solid when tested according to UN-MTC Procedure N.1. No classification is needed.

Description of key information

a) Flammability: The substance is a non flammable solid according to UN-MTC Procedure N.1.
b) Pyrophoric properties: The substance did not deliver indications of pyrophoric properties during the realization of other tests. The determination according to UN-MTC Procedure N.2 is not necessary.
c) A review of the structure and handling and use suggests that there are no chemical groups present that would imply flammability in contact with water. Testing according to UN Procedure N.5 is not necessary.

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

Justification for classification or non-classification

According to the present results the substance does not have to be classified as a flammable, phyrophoric nor a substance that emits flammable gases in contact with water.
