Qualification and validation of process fluids according to DASSAULT Aviation specification DGQT 0.4.2.0065
In nuclear construction and military and business aerospace, validating cutting, cleaning, or temporary protective chemicals is an important step. The DASSAULT Aviation DGQT 0.4.2.0065 directive sets strict safety and performance requirements for fluids used on assembly lines and in machining.
Filab laboratory supports you in characterizing your products and carrying out the regulatory tests required to obtain your Dassault Aviation approval.
The challenges of specification DGQT 0.4.2.0065
Aerospace structures combine high-performance metal alloys with lightweight composite materials. Applying an unqualified fluid can cause invisible but irreversible damage.
Qualification according to the DGQT 0.4.2.0065 standard ensures that the process fluid :
Does not cause corrosion (pitting, intergranular, or stress corrosion) on aluminum alloys, titanium, and high-strength steels.
Does not damage polymers or composites through direct or indirect contact during manufacturing or maintenance operations.
Preserves the integrity of coatings and surface treatments (anodizing, chromate or sulfuric-tartaric conversion coatings, and paints).
Does not leave aggressive residues that could impair adhesion during subsequent bonding or painting operations.
Our testing services according to directive DGQT 0.4.2.0065
Our laboratory testing programs faithfully reproduce the operational exposure conditions required by Dassault Aviation’s General Directorate of Total Quality (DGQT):
Safety testing on metals and alloys
Total and partial immersion corrosion: evaluation on aerospace aluminium alloys, titanium and steels.
Determination of mass loss: precise quantification of chemical attack on calibrated test specimens.
Stress corrosion cracking (SCC): validation on components under mechanical stress.
Staining potential: verification that no discoloration or staining occurs on sensitive alloys.
Assessment of material and surface-condition interactions
Compatibility with paints and sealants: assessment of swelling prevention and retention of adhesion for seals and primary coatings.
Residue analysis after drying: assessment of residue levels and ease of rinsing/cleaning.

Our FAQ
To receive a quote from the laboratory, you can contact our teams via our contact form, by telephone or by email.
Simply send us your requirements (material type, requested analysis, applicable standard, urgency, number of samples, etc.). We will then send you a customized technical and pricing proposal within 24–48 hours.
Analysis turnaround times at the FILAB laboratory vary depending on the type of analysis and the complexity of the expertise project.
FILAB is nevertheless committed to providing fast turnaround times tailored to your industrial constraints and urgent requirements.
The fluids primarily concerned are soluble or straight cutting fluids for machining aluminum and titanium alloys, degreasing and cleaning liquids, inter-operational solvents, and temporary corrosion-protection fluids.
Yes. Several material compatibility and corrosion tests are similar or complementary across AIMS 12-10-000, PR 1500/PR 6300, and DGQT 0.4.2.0065. Our laboratory can design a shared qualification program to reduce your approval costs and timelines.
