Endpoint:

oxidising solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

July 19, 2017 - July 31, 2017

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.17 (Oxidising Properties (Solids))

Deviations:

no

GLP compliance:

yes

Contact with:

powdered cellulose

Duration of test (contact time):

5 min

Key result

Sample tested:

other: The test substance and barium nitrate at a ratio of 2:1 of each substance to dried cellulose powder

Parameter:

maximum burning rate

Result:

> 0 - < 0.513 mm/s

Remarks on result:

mixture does not ignite and burn

See attached tables in attached background material below.

Interpretation of results:

GHS criteria not met

Conclusions:

Under the conditions specified the test substance had an overall maximum burning rate of 0.513 mm/s at a ratio of 10% test substance to 90% dried cellulose powder. The overall maximum burning rate of the test substance was significantly less than the maximum burning rate of the known class 1 oxidizer, barium nitrate (0.649 mm/s). Therefore test substance would not be considered an oxidizer based on the results of this study.

Executive summary:

The oxidising properties study was conducted according to EU Method A.17. A preliminary screening test was performed on the test substance. Since the burning time for the test substance sample was less than the reference substance, barium nitrate, and the vigorousness and flame intensity was significantly greater for barium nitrate, definitive testing was performed. Definitive testing was performed on test substance. A minimum of one sample of test substance was prepared at six test substance to dried cellulose powder ratios (i.e. 10%, 20%, 30%, 40%, 50% and 60% w/w) and each ratio was run at least once. All of the ratios were run an additional five times for a total of six times. The maximum burning rate for each of the sample ratios were plotted versus the respective test substance concentration to determine the overall maximum burn rate. Under the conditions specified, test substance had an overall maximum burning rate of 0.513 mm/s at a ratio of 10% test substance to 90% dried cellulose powder. The overall maximum burning rate of the test substance was significantly less than the maximum burning rate of the known class 1 oxidizer, barium nitrate (0.649 mm/s). Therefore, test substance would not be considered an oxidizer based on the results of this study.
