Applicant's summary and conclusion
- Conclusions:
- The test material does not cause any measurable corrosion to steel or aluminium using this test procedure
- Executive summary:
In a metal corrosion study, (following UN classification procedure "test method and criteria relating to substance of class 8, Test C.1.), metal (Steel and aluminium) were exposed to the test material for 7 days at 55 °C.
No measurable corrosion to steel or aluminium were noticed using this test procedure.
