2002-09-20 - 2003-06-25
Reliability:
1 (reliable without restriction)
Qualifier:
according to guideline
Guideline:
EU Method A.17 (Oxidising Properties (Solids))
Deviations:
no
Principles of method if other than guideline:
NA
GLP compliance:
yes (incl. QA statement)

Key result
Sample tested:
other: not specified
Parameter:
other: not specified
Remarks on result:
other: result not specified
Remarks:
no burning to completion was observed

The test substance was found not to possess oxidising properties under the conditions of the test.

Interpretation of results:
GHS criteria not met
Conclusions:
The test substance was found not to possess oxidising properties under the conditions of the test.
Executive summary:

The test substance was found not to possess oxidising properties under the conditions of the test.

Endpoint:
oxidising properties
Type of information:
experimental study
Adequacy of study:
supporting study
Study period:
2002-04-16 - 2002-07-18
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: according to UN-Guideline (comparable with Guideline study (OECD, EU etc.)
Qualifier:
according to guideline
Guideline:
other: UN Test 0.1 of the Recommandations on the Transport of Dangerous Goods (Manual of Tests and Criteria, 2nd revised edition).
Deviations:
no
Principles of method if other than guideline:
The test method is designed to measure the potential for a solid test substance to increase the burning rate or intensity of a combustible substance. The test substance was mixed with dry fibrous cellulose. The burning characteristics were compared with standard mixtures of potassium bromate and cellulose. The assessment was then used to assign a Packing Group to the test substance.
GLP compliance:
yes
Contact with:
other: dry fibrous cellulose

Since the substance samples did not burn to completion and therefore exceeded the burning time of the 3:7 ratio of the reference substance, the test substance should not be classified as a United Nation class 5.1 oxidizer by test 0.1 tests for oxidizing solids.

Interpretation of results:
other: Since the substance samples did not burn to completion and therefore exceeded the burning time of the 3:7 ratio of the reference substance, the test substance should not be classified in Division 5.1.
Conclusions:
Oxone®: cellulose mixtures were found not to burn to completion and therefore the test substance should not be classified in Division 5.1 according to the UN Transport Regulations.
Executive summary:

Materials and methods


The test method is designed to measure the potential for a solid test substance to increase the burning rate or intensity of a combustible substance. The test substance was mixed with dry fibrous cellulose. The burning characteristics were compared with standard mixtures of potassium bromate and cellulose. The assessment was then used to assign a Packing Group to the test substance.


 


Results and discussion


Since the substance samples did not burn to completion and therefore exceeded the burning time of the 3:7 ratio of the reference substance, the test substance should not be classified in Division 5.1

Description of key information

According to the results obtained form one key and one supporting study, the test substance was found to have no oxidising properties under the conditions of the test.

Key value for chemical safety assessment

Oxidising properties:
no

Additional information

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.
