Endpoint:
oxidising solids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is incapable of reacting exothermically with combustible materials
Endpoint:
oxidising solids
Type of information:
other: expert statement
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
The oxidising properties of the test substance were screened based on the UN Recommendations on the Transport of Dangerous Goods (Orange Book, 3 edition, 1999) where a set of criteria is compiled to evaluate the need for classification of materials as oxidising substances.
Qualifier:
according to guideline

Remarks on result:

Remarks:
See any other information on results incl. tables

The test substance contains oxygen. Most of the oxygen atoms are bonded to sulphur. Thus, the conditions of the UN recommendations are not fulfilled and the oxygen balance was used as third criterion to predict oxidising properties: The oxygen balance of the test substance as calculated according to the UN recommendations and taking carbon, hydrogen and oxygen into consideration, was found to be negative. In principle this means, that there is a surplus of carbon atoms for a complete reaction according to the following reaction scheme:

CxHyOz + [x + (y/4) - (z/2)] O2 → xCO2 + (y/2) H2O

Interpretation of results:
GHS criteria not met
Remarks:
CLP Implementation.
Conclusions:
The product is not capable of causing fire or enhancing the risk of fire when in contact with combustible material.
Executive summary:

The oxidising properties of the substance were screened base: on the UN Recommendations on the Transport of Dangerous Goods (Orange Book, 3 edition, 1999) where a set of criteria is compiled to evaluate the need for classification of materials as oxidising substances. Based on the internationally recognised UN Recommendation criteria and on the oxygen balance, the test substance is considered to be non-oxidising and therefore is not to be tested experimentally for the classification under division 5.1 as oxidising substances. Thus it can be concluded beyond a reasonable doubt that the substance is not capable of causing fire or enhancing the risk of fire when in contact with combustible material.

Description of key information

Key study: The oxidising properties of the substance were screened base: on the UN Recommendations on the Transport of Dangerous Goods (Orange Book, 3 edition, 1999) where a set of criteria is compiled to evaluate the need for classification of materials as oxidising substances. Based on the internationally recognised UN Recommendation criteria and on the oxygen balance, the test substance is considered to be non-oxidising and therefore is not to be tested experimentally for the classification under division 5.1 as oxidising substances. Thus it can be concluded beyond a reasonable doubt that the substance is not capable of causing fire or enhancing the risk of fire when in contact with combustible material.

Data waiving: In accordance with column 2 of REACH Annex VII, the study does not need to be conducted since the substance is incapable of reacting exothermically with combustible materials based on the oxygen balance.

Key value for chemical safety assessment

Oxidising properties:
non oxidising

Additional information

Justification for classification or non-classification

The substance is not classified for oxidising properties in accordance to CLP Regulation (EC) 1272/2008.
