Results and discussion

Results:
The test item does not reach the annual corrosion rate of 6.25 mm/a. Therefore the test item is not to be classified as a metal-corrosive material in class 8, packaging group III, according to the Regulations on the Transport of Dangerous Goods.

After a test period of 21 days there was a low mass loss was recognizable on the test specimen. The limit of the weight loss of 39.2% (21-day test time) was not crossed. The attached images show the test located samples completely dipped, half-dipped, and in the gas phase.
