Materials and methods

Test guideline
Qualifier:
equivalent or similar to
Guideline:
EU Method A.10 (Flammability (Solids))
Principles of method if other than guideline:
The flammability (solids) was determined by measuring the burning rate of test item prepared as a pile of set dimensions. Testing was conducted using a procedure designed to be compatible with Method A 10 Flammability (Solids) of Commission Regulation (EC) No 440/2008 of 30 May 2008.
GLP compliance:
yes (incl. certificate)

Results and discussion

Pyrophoric solids
Test procedure:
ignition time on contact with air
Remarks:
Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
Remarks on result:
no ignition on contact with air (not further specified)
Remarks:
corresponding to 'no' in migrated source record.
Pyrophoric liquids
Test procedure:
ignition time on contact with air
Remarks:
Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
Remarks on result:
no ignition on contact with air (not further specified)
Remarks:
corresponding to 'no' in migrated source record.

Any other information on results incl. tables

* Preliminary screening test:

The pile failed to ignite during the two minutes that the Bunsen flame was applied. The result of the preliminary screening test obviated the need to perform the main test.

* Moisture content:

   Determination A  Determination B
 a) Mass of loss bottle (9)  19.7317 20.9650 
 b) Mass of loss bottle and test item (9) 20.7695  22.0703 
 c) Mass of loss bottle and test item after drying (g) 20.7692  22.700 
 Moisture content (% w/w) < 0.1  < 0.1 
 Mean moisture content (% w/w)  <0.1  

Applicant's summary and conclusion

Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
The test item has been determined to be not highly flammable as it failed to ignite in the preliminary screening test.
Executive summary:

6H-Dibenz [c,e] [1,2] oxaphosphorin 6,6'( 1,2-ethanediyl) bis-6,6'-dioxide is not highly flammable, using a procedure designed to be compatible with Method A 10 Flammability (Solids) of Commission Regulation (EC) No 440/2008 of 30 May 2008.
