Fluid resistance tests
Validate the resistance of equipment and its materials to contamination by fluids
Why carry out fluid resistance tests?
- Assessing the resistance of equipment and the materials that make it up to fuels, oils, solvents, cleaning fluids and other contaminants.
- Test compliance with industry standards to guarantee the expected performance of equipment.
- Optimise the selection of materials used in the manufacture of equipment**
- Validation of equipment marking or labelling
Types of fluid resistance tests
Our laboratories are equipped to carry out a variety of tests:
- Prolonged immersion: Simulation of prolonged contamination.
- Spraying, coating and soaking: Simulation of occasional or intermittent contamination
CBRN (chemical, biological, radiological, and nuclear) testing - Equipment resistance testing with decontamination products.
At our Saint-Chamond facility (near Lyon), we conduct tests on equipment resistance to decontamination products in a CBRN context.
These tests on resistance to decontamination products mainly comply with NATO STANAG 4370 and US MIL-STD 810 standards.

Our testing capabilities and technical resources
Test equipment
The Emitech Group's test benches can be used to carry out tests on samples or on complete, functional equipment following different application procedures for spraying, immersion and coating:
- Fume cupboard test rig: Controlled immersion and spraying.
- Climatic chambers: Storage under different temperature conditions.
- Visual inspection (light booth) and functional inspection after testing

Types of fluids tested
- Fuels (JP-8, JP-5, etc.) and hydraulic fluids (H-515, H-537, etc.)
- Brake fluids (G-353, G-359...) and lubricating oils (O-142, S-1748...)
- Solvents and cleaning agents.
- Insecticides (Callington, etc.), disinfectants and extinguishing agents (FM200, Halotron, etc.)
- Sweat, coffee, soda and other everyday liquids.
Standards applicable to fluid resistance tests
Our tests comply with the main international regulations:
- RTCA DO-160 Section 11: Tests for aeronautical equipment.
- MIL-STD-810 Section 504: Military fluid resistance tests.
- ISO 16750-5: Chemical stresses on road vehicles.
- EN 3475-411: Electrical cables for aeronautical use.
- EN 3909: Fluid tests for electrical and optical components and sub-assemblies.
- STANAG 4370, GAM EG-13: Specific standards for military applications.
Failure modes identified during testing
Fluid resistance tests identify several types of damage:
- impairment of mechanical and electrical performance** **Corrosion and cracking of materials
- **corrosion and cracking of materials
- **Swelling, blistering and delamination of coatings **
