Reference

Endpoint:

oxidising solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

May 27, 2013

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:

not specified

Key result

Sample tested:

test mixture as specified

Remarks:

ratio 2:1 test substance/cellulose

Parameter:

preliminary test

Remarks on result:

mixture does not ignite and burn

Remarks:

The test substance was milled with a centrifugal mill to < 0.125 mm. The test substance could not be dried with 105°C, because it melts. Therefore, the moist salaly was determined. Moist salaly = 0.38%.

Preliminary test

The preliminary screening test showed no propagation of the flame and the flame ceased. Therefore, the full test was carried out.

 

Train test

The mixtures in the range of 10 to 90 % test substance/cellulose showed no propagation of the flame and the flame ceased after a few seconds.

Interpretation of results:

GHS criteria not met

Conclusions:

Under the study conditions, the test substance was not oxidizing.

Executive summary:

A study was conducted to determine oxidizing properties of the test substance according to EU Method A.17. Initially, a preliminary screening study was carried out on a mixture of test substance with dried cellulose in a ratio of 2:1. This was followed by the full train test with range of mixtures of the test substance with cellulose and reference substances. A hot flame from a gas burner with a diameter of about 6 mm was used as ignition source in both tests. The preliminary screening test showed no propagation of the flame and the flame ceased. Therefore, the full train test was carried out. In the full train test, the mixtures in the range of 10 to 90 % test substance/cellulose showed no propagation of the flame and the flame ceased after a few seconds. Under the study conditions, the test substance was therefore not oxidizing (Bütfering, 2013).
