How resistant to chemicals are the SIMATIC HMI operator panels and Industrial PCs?
The PDF file lists all the devices whose fronts1) have been tested and whose fronts1) have the same properties as reference devices.
1) Fronts consist of the decor foil, plastic, seal and touch foil (on Touch devices).

1. Test conditions and type of chemical substances
The chemical substances tested and the test conditions are listed below. The test pieces were coated once with the media.
|Test media and test conditions:|
|1||Honing oil Castrol Honilo 981||50||72|
|6||Hydrochloric acid 10%||20||1)|
|8||Caustic soda solution 10%||20||1)|
|13||Brake fluid DOT 4||50||72|
|14||H2O2 (hydrogen peroxide) 10%||20||72|
1) 10 cycles over a total period of 72 hours: spray on, then leave to dry.
2. Chemical resistance of fronts
The following chemical substances are to be classed according to the following table:
|1||Honing oil Castrol Honilo 981||No recognizable change.|
|2||Premium-grade gasoline||No recognizable change.|
|3||Diesel oil||No recognizable change.|
|4||Rape oil||No recognizable change.|
|5||Linseed oil||No recognizable change.|
|6||Hydrochloric acid 10%||Test piece shows signs of discoloration.|
|7||Sidolin streak-free||No recognizable change.|
|8||Caustic soda solution 10%||Test piece shows signs of discoloration.|
|9||Ethyl alcohol||No recognizable change.|
|10||Benzine HAKU||No recognizable change.|
|11||Solvent (alkaline)||No recognizable change.|
|12||Acetone||Test piece shows signs of discoloration.|
|13||Brake fluid DOT 4||No recognizable change.|
|14||H2O2 (hydrogen peroxide) 10%||No recognizable change.|
Adhesives do not have a long-term resistance to aggressive oils, cleaning agents and solutions.
3. Single gas test in compliance with DIN EN 60068-2-42
Only the fronts1) were tested, not the complete devices.
1) Fronts consist of decor foil, plastic, seal and touch foil (on Touch devices).
|Test duration||10 days|
|Test result||No recognizable change.|
