Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Endpoint:
oxidising solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Study was conducted between 3 June 2010 and 4 June 2010
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: GLP compliant guideline study.
Qualifier:
according to guideline
Guideline:
EU Method A.17 (Oxidising Properties (Solids))
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Remarks:
25 February 2009
Contact with:
powdered cellulose
Key result
Sample tested:
other: Mixed Ash/Cellulose 1:2
Remarks:
Preliminary screening test
Parameter:
preliminary test
Remarks on result:
other: Sample briefly ignited with a small, orange flame, which extinguished after 2 seconds, some localised glowing also observed. 
Remarks:
Moderate reaction

Table 1. Preliminary Screening Test

  No Reaction  Moderate Reaction  Vigorous Reaction 
Mixed Ash/Cellulose (2:1)  N/A  Sample briefly ignited with a small, orange flame, which extinguished after 2 seconds, some localised glowing also observed.   N/A
Barium Nitrate/Cellulose (2:1)  N/A   N/A Vigorous reaction, burnt with a green flame. 
Time (secs)  N/A   N/A  51

Comment: The burning time of Mixed Ash was far greater than the reference sample in the preliminary screening test, therefore no further testing is required as the sample is not classified as an oxidising solid.

Results - Not an Oxidising Solid

Interpretation of results:
other: no oxidising properties
Conclusions:
Ash was found to be a non-oxidising solid.
Executive summary:

Oxidising properties of Ash were determined in a GLP laboratory according to the Method A17 Oxidising Properties (solids) Test in Comission Regulation (EC) 440/2008. According to the preliminary screening test, the test material was found to be a non-oxidising solid.

Description of key information

Oxidising properties of Ash were determined in a GLP laboratory according to the Method A17 Oxidising Properties (solids) Test in Comission Regulation (EC) 440/2008. According to the preliminary screening test, the test material was found to be non-oxidising solid.

Key value for chemical safety assessment

Oxidising properties:
no

Additional information

Justification for classification or non-classification

Ash was not found to have oxidising properties according to the Method A17 Oxidising Properties (solids) Test in Comission Regulation (EC) 440/2008. Thus, no classification is required.
