Qualifier:
according to guideline
Guideline:
other: United Nations Recommendations on the Transportation of Dangerous Goods, Manual of Tests and Criteria for substances of Class 4, Division 4.2
Version / remarks:
UN Manual of Tests and Criteria: Test N.4 (Test method for self-heating substances)
Deviations:
not specified
GLP compliance:
yes
Remarks on result:
no self ignition observed under the test conditions

Appearance before test: White crystalline solid.

Appearance after test: The sample had hardened to a solid mass with no change in its initial volume.

It was determined that the test substance should be classified as not a self-heating substance of Class 4, Division 4.2.

Conclusions:
It was determined that the test item should be classified as not a self-heating substance of Class 4, Division 4.2.
Executive summary:

The self-heating properties of the test item were determined in a GLP study according to UN Manual of Tests and Criteria: Test N.4 (Test method for self-heating substances). It was observed that in appearance the test item changed from white crystalline solid to a hardened solid mass with no change in its initial volume.

No self-ignition took place during testing. The substance should be classified as not self-heating substance.
