Results and discussion

Results:
Both materials tested showed no corrosion attack. The corrosion rates of all the coupons tested were below 0.01mm/a. All specimens tested did
not exhibit any signs of localized corrosion.
Test medium: 35% aqueous solution
The coupons made of carbon steel showed no corrosion attack whereas the aluminium alloy was substantially attacked. The coupon completely
immersed tested showed a thick yellow-brown spotted coverage on the surface and the coupon tested in the vapour phase exhibited a thin brown
coverage on the surface. Both coverages could only mechanically be removed by scraping. The corrosion rates of all the coupons made of steel
tested in this medium were below 0.01mm/a. The coupons made of the aluminium alloy exhibited corrosion rates up to 1.7mm/a. Any signs of
localized corrosion were not detected on the coupons.
Transformation products:
no

Applicant's summary and conclusion

Conclusions:
Due to the test results the substance where not classified as corrosive to metals. In both media is has not to be classified in class 8 products, packing group III (minor corrosive).
