Adequacy of study:
key study
Study period:
2012
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Follows EU Method A.17 (Oxidizing properties)
Reason / purpose:
reference to same study
Qualifier:
according to
Guideline:
EU Method A.17 (Oxidising Properties (Solids))
Version / remarks:
These deviations do not have any impact on the results
Deviations:
yes
Remarks:
1) Due to the agglomeration of the powder, the test item was sieved at 500 μm instead of 125 μm. 2) No intermediate weighing was made during the cellulose drying procedure. However, cellulose was dried at a mean temperature of 106 °C during 5 days.
Principles of method if other than guideline:

Conclusions:

The maximum burning rate obtained with the test item was:

3.39 mm/s for the test item / cellulose mixture (10/90%).

The maximum burning rate obtained with the reference item was:

3.92 mm/s for the reference item / cellulose mixture (50/50%).

The maximum burning rate of test item / cellulose mixture was slower than the maximum burning rate with reference item / cellulose mixture.


The test item was not considered to have oxidizing properties under the experimental conditions used.
Executive summary:

In compliance with

Commission Directive 92/69/EEC, Commission Regulation (EC) No. 440/2008
EC A17 Method (2008)
