Applicant's summary and conclusion

Conclusions:
6H-Dibenz [c,e] [1,2] oxaphosphorin 6,6'( 1,2-ethanediyl) bis-6,6'-dioxide has been determined not to have a relative self-ignition temperature below its melting temperature.
Executive summary:

Relative Self-Ignition Temperature for Solids. No relative self-ignition below the melting temperature of the test item, using a procedure designed to be compatible with Method A16 Relative Self-Ignition Temperature for Solids of Commission Regulation (EC) No 440/2008 of 30 May 2008.
