Applicant's summary and conclusion
- Conclusions:
- The test material sodium percarbonate is not classified as corrosive towards container materials in accordance with the UN criteria for air and sea transportation.
- Executive summary:
A test on corrosivity of sodium percarbonate towards container material was carried out in accordance with the NACE-standard TM 0169 -95 and the results of the test are considered as reliable with restrictions. Pieces of an aluminium alloy containing zinc, manganese and copper and unalloyed steel were placed in sodium percarbonate moistened with 5 % deionised water (two samples per material). The samples were stored in a board for seven days at 55 °C. The abrasion of material was evaluated after having cleaned the materials properly. The experimentally determined abrasion rates were 0.054 and 0.064 mm/a. A classification is required at values equal to or above 6.25 mm/a so that the substance was not classified as corrosive towards container materials in accordance with the UN criteria for air and sea transportation.
