Description of key information

Experimental determination of metal corrosion : the test item isn't corrosive on metal (steel and aluminium alloy)

Additional information

The corrosiveness of the test item was determined according to UN manual of tests and criteria part 37. The dimension of specimen of metal are 10*50*2 mm instated of 20*50*3 mm. This deviation don't impact the result of the test.

All the weight loss values are much lower than 13.5% (for both carbon steel and aluminium alloy). Furthermore, the average depth of pits present on the carbon steel surface exposed to the gas cap (deepest attacks) was 20µm, (less than 120µm). Based on these observations, it was conclude that :the test item isn't corrosive on metal.
