Key result

Sample tested:

test mixture 1:1

Parameter:

mean pressure rise time

Result:

34.97 s

Interpretation of results:

GHS criteria not met

Conclusions:

Based on the comparison of the test series, it can be stated, that mean pressure rise time of the 1:1 mixture, by mass, of the test item and cellulose is greater than the mean pressure rise time of the 1:1 nitric acid (65 %)/cellulose mixture. Therefore the test item is classed as a Not Division 5.1 material according to the UN Recommendations on the Transport of Dangerous Goods, as it exhibits a mean pressure rise time greater than the mean pressure rise time of 65 % (w/w) nitric acid and cellulose.

Executive summary:

The purpose of this study was to measure the potential for the test item to increase the burning rate or burning intensity of a combustible substance when the two are thoroughly mixed, or to form a mixture with a combustible substance which spontaneously ignites. In the course of this study tests were performed in order to measure the potential of the test item to increase the burning rate or burning intensity of fibrous cellulose when the two are thoroughly mixed in a 1 to 1 ratio. The mixture was heated in a pressure vessel and the rate of pressure rise was registered. On the basis of the test results it was decided, that the test item is not an oxidising substance of Division 5.1. The following mean pressure rise times were obtained: Nitric acid (65 %): 1.79 sec; test item: 34.97 sec.

Description of key information

Based on the comparison of the test series, it can be stated, that mean pressure rise time of the 1:1 mixture, by mass, of the test item and cellulose is greater than the mean pressure rise time of the 1:1 nitric acid (65 %)/cellulose mixture. Therefore the test item is classed as a Not Division 5.1 material according to the UN Recommendations on the Transport of Dangerous Goods, as it exhibits a mean pressure rise time greater than the mean pressure rise time of 65 % (w/w) nitric acid and cellulose.

The test item has not to be classified as oxidising solid, oxidising liquid or oxidising gas.

Oxidising liquids

The purpose of this study was to measure the potential for the test item to increase the burning rate or burning intensity of a combustible substance when the two are thoroughly mixed, or to form a mixture with a combustible substance which spontaneously ignites. In the course of this study tests were performed in order to measure the potential of the test item to increase the burning rate or burning intensity of fibrous cellulose when the two are thoroughly mixed in a 1 to 1 ratio. The mixture was heated in a pressure vessel and the rate of pressure rise was registered. On the basis of the test results it was decided, that the test item is not an oxidising substance of Division 5.1. The following mean pressure rise times were obtained: Nitric acid (65 %): 1.79 sec; test item: 34.97 sec.

Oxidising gases

The test item is a liquid at ambient conditions. This hazard class is only applicable for gases. Thus, the substance was not considered for classification as oxidising gases.

Oxidising solids

The test item is a liquid at ambient conditions. This hazard class is only applicable for solids. Thus, the substance was not considered for classification as oxidising solid.

Justification for classification or non-classification

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. Based on available data on oxidising properties, the test item is not classified according to Regulation (EC) No 1272/2008 (CLP), as amended for the tenth time in Regulation (EU) No 2017/776.
