Storage stability / reactivity towards container material:

other: The test substance showed not changes in the 14 days storage test at elevated conditions (54 °C). Materials tested in this study (aluminium, brass, copper, steel, stainless steel, PE and PP) showed no corrosion signs (e.g. pitting or rust).

Results of the 14 d corrosion study at elevated temperature according to EPA OPPTS 830.6313 / 6320:

The 14 days storage of the test substance, technical substance, at elevated (54 °C) conditions showed no colour changes or clumping of the test item. The immersed part of the test material strips of aluminium, brass, copper, steel, stainless steel, PE and PP shows no changes in their physical appearance.

To conclude, from the materials tested in this study: aluminium, brass, copper, steel, stainless steel, PE and PP showed no corrosion signs (e.g. pitting or rust) and can all be used for storing the test substance, technical material.
