Fluid contamination

Fluid Contamination

Many products may be used in an environment where various fluids may be accidentally or intentionally be in contact with it and may contaminate it (from the simple coffee to fuel used in airplane).

Besides the nature of the fluid, different parameters can intervene to influence the contamination process such as temperature.

 

Expertise

  • Testing following RTCA DO 160 / MIL STD 810 standards

Contamination aux fluides

 

Products

  • Fuel
  • Oils
  • Grease
  • Cleaner
  • Hydraulic fluids
  • Decontaminants
  • Extinguisher products

Climatic Tests

Heat, cold, humidity, shocks, rapid temperature variation

The exposure to the natural elements under various conditions are the basis of climatic qualifications.
