Reference

Reference 1

Endpoint:

oxidising solids

Type of information:

experimental study

Adequacy of study:

key study

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.3 (Gravimetric test for oxidizing solids)

GLP compliance:

yes (incl. QA statement)

Key result

Sample tested:

1:1 sample-to-cellulose ratio

Parameter:

burning rate

Result:

0.04 g/s

Sample tested:

4:1 sample-to-cellulose ratio

Parameter:

burning rate

Result:

0.01 g/s

Results

 

Preparation of test substance and ref erence substance
According to the regulation the test substance was ground to a particle size <500 μm .
Technically pure Calcium peroxide with nominal particle sizes < 75 μm was used as reference substance. Dried fibrous cellulose with a fiber length between 50 and 250 μm was used as the combustible material . lt was dried at 105°C to constant mass.

 

Reference mixtures

Calciumperoxide : Cellulose	Mean burning rate from 5 tests g/s
1:2	0.12
3:1
1:1

 

Test mixtures

Test substance : Cellulose	Mean burning rate from 5 tests g/s
4:1	0.01
1:1	0.04

 

Interpretation of the results

The test substance is not considered an oxidizing substance because the mean burning rate of the mixtures tested is less than the mean burning rate of the reference mixture.
The result does not lead to a classification.

Description of key information

No oxidising properties

Key value for chemical safety assessment

Oxidising properties:

non oxidising

Additional information

Two GLP studies were performed in accordance with the test method described in the UN Manual of Tests and Criteria, Part III, Test O.3. Both forms of the test substance was not considered an oxidizing substance because the mean burning rate of the mixtures tested is less than the mean burning rate of the reference mixture.

Justification for classification or non-classification

In accordance with Annex I, Section 2.4, Section 2.13 and Section 2.14 of Regulation (EC) No 1272/2008 and UN GHS Rev 6 (2015) the substance has not to be classified as oxidising gas, oxidising liquid or oxidising solid in class 5 Division 5.1.
