Constituent 1
- Specific details on test material used for the study:
- Testing material: steel of type S235JR+CR (1.0037), S275J2G3+CR (1.0144) or similar and non coated aluminum type7075 -T6 or AZ-5GU-TG. The oxide layer on aluminum has to be removed directly before testing.
A substance is classified Dangerous Good of Class 8, if in one concentration of its aqueous solutions the corrosion rate exceeds the threshold of 6.25 mm/year at a test temperature of 55 °C. ln case of localized corrosion (like pitting) beside or instead of the uniform corrosion, the deepest intrusion depth needs to be taken for the evaluation.
Test duration was 28 days at 55 °C.
1.5 L (apparent density) of graphite, acid-treated has been filled up with 1 L deionized water.
Results and discussion
- Results:
- The pH at the beginning was 5.5 and at the end 5 in both vessels. Slight uniform but no significant localized corrosion has been observed. The strongest corrosion attack occurred at the steel specimens exposed to the vapor phase. All corrosion rates are below the threshold values.
- Transformation products:
- not measured
Applicant's summary and conclusion
- Conclusions:
- From the corrosion related point of view, the tested product is no Dangerous Good of Class 8 ,,Corrosive Substances" according to regulations for transportation on road (ADR, GGVS), by ship (IMDG-Code/GGVSee) and in air (IATA-regulations), and it is not "corrosive" according GHS.
- Executive summary:
Corrosive effects of graphite, acid-treated have been evaluated regarding its classification as Dangerous Good of Class 8 ,,Corrosive Substances".
For this purpose 1.5 L of graphite, acid-treated has been filled up with 1 L deionized water. The test has been performed on 3 plates each, made of steel- and aluminium-material; the plates were fully and half immersed in the solution, and exposed in the vapour phase for 28 days at 55 °C.
Slight uniform but no significant localized corrosion has been observed. The strongest corrosion attack occurred at the steel specimens exposed to the vapor phase. All corrosion rates are below the threshold values.
The tested substance has not to be classified as Dangerous Good of Class 8 ,,Corrosive Substances" according to regulations for transportation of goods on road (ADR, GGVS), by ship (IMDG-Code/GGVSea) and in air (IATA-regulations). lt is also not "corrosive" according GHS. The assessment is solely related to the classification regarding the corrosion behavior. Testing the burning effect on skin and mucous membrane was not subject of the carrried out test.
