Endpoint:

oxidising solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

26 Sep 2016 to 27 Oct 2016

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

UN Manual of Tests and Criteria: Test O.1 (Test for oxidizing solids)

Version / remarks:

5th Revised Edition, 2009

GLP compliance:

yes

Contact with:

powdered cellulose

Key result

Sample tested:

4:1 sample-to-cellulose ratio

Parameter:

mean burning time

Result:

282 s

Sample tested:

1:1 sample-to-cellulose ratio

Parameter:

mean burning time

Result:

195 s

Sample tested:

reference: 3:7 mixture potassium bromate + cellulose

Parameter:

mean burning time

Result:

70 s

RESULTS:

Applied power to the ignition coil: 150 ± 7 W. The burning times for the test substance and reference substance mixtures with cellulose are tabulated below. In all cases the mixtures burned fully with a flame.

Test No.	Burning Times (s)
	Test Substance		Reference
	4:1	1:1	3:7
1.	282	229	96
2.	273	184	56
3.	336	162	61
4.	268	170	73
5.	252	228	62
Mean	282	195	70

 

Interpretation of results:

GHS criteria not met

Conclusions:

The mean burning times of the test substance/cellulose mixtures are both greater than the mean burning time of the potassium bromate/cellulose mixtures.

Executive summary:

To determine the oxidizing properties of the substance a study was performed according to UN Test O.1 and in compliance with GLP. In this study the mean burning times of the test substance/cellulose mixtures is greater than burning time of the potassium bromate/cellulose mixtures. In accordance with the criteria of UN Test O.1, the test substance is not classified as an oxidizing solid.

Description of key information

The mean burning time of the test substance/cellulose mixtures is greater than that of the reference mixture, UN Test O.1, Jackson 2016

Key value for chemical safety assessment

Oxidising properties:

non oxidising

Justification for classification or non-classification

Based on the available information, classification for oxidising properties is not warranted in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. (EC) 1272/2008.
