Qualification of aerospace fluids according to BOEING BAC 5008

Fluids used by the Aerospace industry in the manufacture, assembly, maintenance or protection of components can directly affect surface cleanliness, material compatibility and contamination risk control. The qualification of aerospace fluids aims to assess their suitability against applicable requirements before implementation or when there is a change in formulation, supplier, process or batch.

As part of an approach related to BOEING BAC 5008, Filab laboratory supports manufacturers in defining an analysis plan consistent with the fluid’s actual use, the materials in contact with it and the customer’s documentary requirements.

Filab laboratory works with aerospace fluids such as cleaners, degreasers, lubricants, oils, hydraulic fluids, cutting fluids, release agents, temporary protective products and surface treatment solutions. The nature of the product, its physical state and its application method determine the analytical program.

A technical discussion helps clarify the product’s status, its application, contact conditions, references to be compared, available documentation and the expected decision. This preliminary assessment is essential for distinguishing between incoming inspection, non-conformity investigation, comparative study and initial qualification.

Analytical resources may include infrared spectroscopy to identify or compare chemical families, chromatography to study organic compounds, mass spectrometry for targeted or non-targeted identification, and elemental analysis to detect or quantify certain elements. The selected methods depend on the required sensitivity and the matrix.

Qualification is not limited to comparing a technical data sheet. It requires identifying the fluid’s critical parameters, the risk of residues after application, possible interactions with substrates and process conditions. Filab laboratory structures its investigations according to the qualification objective: product comparison, contamination investigation, compliance testing, characterization of a deviation or support for industrial validation.

Depending on the matrix and the issue being investigated, this approach can be supplemented by rheological analysis of complex fluids to assess behavior relevant to the conditions of use.

Investigations may focus on composition, organic compounds, inorganic elements, contaminants, non-volatile residues, volatility, viscosity or other physicochemical properties defined in the qualification protocol. Tests are selected to answer an identified industrial question, without extrapolating beyond the data obtained.

Filab laboratory uses complementary techniques according to the objectives: spectroscopy, chromatography, elemental analysis, physicochemical measurements and residue characterization. When qualification is part of a manufacturing change, an industrial process audit can help link the analytical results to the implementation conditions.

Comparisons between a reference product and a candidate product can be supported by analytical fingerprints and targeted measurements. In the event of a production deviation, Filab laboratory can help identify contamination, a formulation variation or a change in physicochemical properties, and then define the additional analyses required.
