Parameter:

maximum burning rate

Result:

0.87 other: mm/s (migrated information)

Remarks on result:

other: The maximum burning rate for the reference substance-cellulose mixture was 0.87 mm/s at 60% reference substance.

Any other information on results incl. tables

Main Test:

 

The results from the reference substance-cellulose mixtures are shown in Table 9 and Table 10. Results from the test substance-cellulose mixture are listed in Table 11.

 

The maximum burning rate for the reference substance-cellulose mixture was 0.87 mm/s at 60% reference substance.

Flame treatment of the test substance-cellulose mixtures effected swelling of the mixture followed by a short time ignition and extinction of the flame, no burning distance could be determined in any of the cases of the different ratios of the mixture.

Conclusion:

As no burning of the test substance-cellulose mixture occurred in any case of a different ratios of the mixture “D-VAL-DANE” was not classified as oxidizing.
