Constituent 1
- Specific details on test material used for the study:
- Approximately 1 litre of Rhodafac AAP XLP was charged to a 2 litre jacketed glass vessel fitted with reflux condenser and heated using an external Haake oil heater/circulator. Three pre-weighed test coupons were suspended by PTFE tape such that one was fully immersed in the liquid, one half-immersed and the other suspended in the vapour space above the liquid surface. Separate tests were run for aluminium and steel coupons. The vessel was heated at 55°C for 7 days. The coupons were removed from the vessel and washed in acetone. All loose deposits were removed with a plastic brush and the coupons were rinsed again with acetone, dried and re-weighed.
Results and discussion
- Results:
- The weight losses recorded for the fully immersed coupons were equivalent to maximum corrosion rates of:
+0.83 mm/year for steel
+0.30 mm/year for aluminium.
During the tests the immersed surfaces of both metals became coated with a black film. This was more noticeable on the steel coupons. The film could be washed off in acetone.
No effervescence was seen at the immersed surfaces.
None of the coupons showed any visible evidence of localized corrosion such as pitting or blistering.
There was no visible evidence of accelerated corrosion to the half immersed coupons at the air/liquid interface.
Metal surfaces that were exposed only to the vapour space were not corroded at all. - Transformation products:
- not specified

Applicant's summary and conclusion
- Conclusions:
- Based on the experimental results, the substance was considered to be non corrosive to metal
- Executive summary:
Coupons of metal (aluminium and steel) were exposed to Rhodaphac AAP in diferents conditions (fully immersed, half immersed and suspended in the vapour space) following the UN classification procedure, test methods and criteria relating to substances of class 8, Test C1. The experimental vessel was heated at 55°C for 7 day.
In this condition, the fully immersed coupons were equivalent to maximum corrosion rates of
+ 0.83 mm/year for steel
+ 0.30 mm/year for aluminium
