Resistance to oil and chemicals
DIN EN ISO 175
Physical and/or chemical processes/reactions
can occur as a result of external media,
such as liquids or gases. This can result
in a change to the plastic's properties,
the plastic becoming damaged or even
destroyed. The printings and labelings can
also be affected by these changes.
In order to prevent this from happening,
Phoenix Contact uses only plastics and
printing/labeling materials which have been
tested in accordance with DIN EN ISO 175.

Resistance to solvents
EN 60464-2:2001
Printings and labelings must be resistant to
solvent vapors. Therefore, in accordance
with the aforementioned standard,
exposure to solvents is continued over
10 days in the following atmospheres:
• Acetone
• n-hexane
• Ethanol
The labelings and printings must still be
legible after the 10-day exposure.
Phoenix Contact marking materials are
solvent-resistant and fulfill the stringent
requirements.
