  • Corrosion rate of the silver test piece < 200 Å/month

Particulate pollutant

  • The ISO14664-1 Class 8 requirements are met.

    It is recommended that a professional company monitor particulate pollutants in the equipment room.

  • There is no explosive, conductive, magnetic, or corrosive dust in the equipment room.
