Reference
Endpoint:
oxidising solids
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
UN Manual of Tests and Criteria: Test O.1 (Test for oxidizing solids)
Deviations:
yes
Remarks:
The wire diameter and resistance deviate slightly from the UN method, because a wire with the specification stated in UN O.1 is commercially not available, but provides the same electrical power with a voltage of 15.6 V and an electric current of 9.6 A.
GLP compliance:
no
Contact with:
powdered cellulose

Interpretation of results:
Category 3 (oxidising solids) based on GHS criteria
Conclusions:
The mixture the 4:1 ratio of test substance L-Tyrosine, N-acetyl-3,5-dinitro- shows a short-er mean burning time than the 1:1 ratio.
The mean burning time of the test substance mixture (4:1) was less the mean burning time of the mixture of reference substance and cellulose (3:7).
Therefore, the test substance L-Tyrosine, N-acetyl-3,5-dinitro- is classified to be oxidising and the criteria for determining oxidizing properties of the substance is:
Packing group III:
Any test item which, in the 4:1 or 1:1 test item-to-cellulose ratio (by mass) tested, exhibits a mean burning time equal to or less than the mean burning time of a 3:7 mixture (by mass) of potassium bromate and cellulose; and which does not meet the criteria for packing groups I and II.
The same definition applies for the classification according to CLP. Thus the test substance is classified as oxidising solid category 3 according to CLP.

Description of key information
