Reference
Endpoint:
oxidising solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2004-2006
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:
Study was carried out according to generally valid and internationally accepted testing guidelines and under GLP. Test substance is adequately characterised. Therefore full validation applies.
Reason / purpose for cross-reference:
reference to same study
Qualifier:
according to guideline
Guideline:
EU Method A.17 (Oxidising Properties (Solids))
Version / remarks:
Cited as Directive 92/69/EEC, A.17
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Remarks:
Assessment of conformity with GLP on March 5, 2004; certificate date 17th May 2004
Contact with:
powdered cellulose
Key result
Sample tested:
test mixture as specified
Parameter:
preliminary test
Result:
3 s
Remarks on result:
vigorous reaction in the preliminary test
Remarks:
The reaction is instantaneous and very vigorous (time of reaction: 3 seconds).

Combustion is complete with production of an intense flame and important smoke.

Based on the result of the screening test, it was not necessary to carry out the full test.

Interpretation of results:
Category 1 (strong oxidising solids) based on GHS criteria
Conclusions:
The test item is to be considered as Oxidizing Solid according to Directive 67/548/EEC.
Executive summary:

The oxidising properties of test item were determined acccording to EU method A.17 and under GLP.

The test item has oxidising properties under the test conditions.

This means that according to Directive 67/548/EEC, this material is considered as Oxidising Solid.

This data is considered as a key data.

Description of key information

Oxidizing solid Cat. 1. according to Regulation (EC) 1272/2008 (CLP regulation) and UN Globally Harmonised System (GHS). (worst Category)

Key value for chemical safety assessment

Oxidising properties:
oxidising

Additional information

A fully reliable experimental study, conducted according to a recognized EC method and under GLP, is available.

The reaction in the EU A.17 screening test is instantaneous and vigorous (time of reaction: 3 seconds). This means that according to Directive 67/548/EEC, sodium chlorate is considered as oxidizing.

Oxidising properties are also anticipated for the registered substance under Regulation (EC) 1272/2008 (CLP regulation). Considering the reaction in the EU A.17 screening test, no further testing was considered.

Justification for classification or non-classification

Based on the information indicated above the test substance is classified as Oxidizing Solid Cat. 1according to Regulation (EC) 1272/2008 (CLP regulation) and UN Globally Harmonised System (GHS).
