Where can i have ISO 9227-compliant salt spray tests carried out?

Industries looking for a salt spray test in accordance with ISO 9227 generally have a clear objective: compare materials, validate a surface treatment, verify the performance of a coating, or document a non-conformity. Choosing a laboratory should not be limited to the availability of a test chamber. You also need to ensure control of the exposure conditions, traceability of the tests, interpretation of the acceptance criteria, and the ability to complement the test with physicochemical analysis when corrosion needs to be understood in depth. In this context, an independent laboratory such as FILAB, with a quality system in accordance with ISO 17025, is a relevant support for making your technical decisions more reliable.

A good laboratory must understand your specifications: type of specimens or parts, surface condition, coating, exposure duration, rating criteria, need for comparison between batches or suppliers, and expected deliverables. It must also be able to help you define the test framework if your specification refers to ISO 9227 without fully defining the result-reading conditions.

If corrosion is suspected to be linked to surface pollutants or manufacturing residues, analysis for chlorine, bromine, fluorine, sulfur, or metals can be carried out. The techniques that can be used include ion liquid chromatography, ICP-MS, ICP-AES, UV-Visible spectroscopy, or ionometry depending on the element being sought. These methods are particularly useful for corrosion risk assessments, chemical cleanliness checks, or certain material qualification procedures.

FILAB supports manufacturers with an approach tailored to the need: method validation, investigation after non-conformity, comparison of material or treatment solutions, and interpretation of results in a production or qualification context. This support is useful when the salt spray test is only one step in a broader reliability or corrosion risk control case.

Beyond exposure in a salt chamber, the challenge is often to link the observed result to the material composition, process residues, the presence of halogens, sulfur, inorganic impurities, or a surface defect. A testing and analysis laboratory able to deploy complementary techniques makes it possible to go further than a simple visual assessment. This approach is useful for sectors subject to high requirements in reliability, supplier qualification, production validation, or failure analysis after a breakdown.

When corrosion is linked to a contaminant, a washing residue, or elemental composition, it is useful to be able to complement the test with in-house analysis: element quantification by ICP-MS or ICP-AES, anion screening by ion chromatography, characterization of organic residues, or surface study. For more advanced investigations, tools such as analysis Fib Tof Sims can help explain the degradation mechanisms depending on the nature of the case.

Understanding degradation may also require the search for organic compounds, total hydrocarbons, or other residues from cleaning, packaging, or the process. Techniques such as GC-FID, measurement of TOC, or approaches such as analysis Hs Gcms may be relevant depending on the matrix and the objective. At the same time, surface observation and characterization make it possible to link the corrosion test to the material's actual condition.

The FILAB laboratory relies on a 5,200 m² analytical platform and on in-house services to provide a comprehensive service. Its quality system under COFRAC ISO 17025 accreditation for numerous analysis is a real asset for manufacturers seeking rigor, traceability, and responsiveness. Depending on the need, expertise in corrosion, contaminant analysis, and materials characterization can be mobilized, notably through the Laboratoire analysis Met.

To get started effectively, it is important to specify the nature of the parts, the number of samples, the material or coating, the purpose of the test, the target exposure duration, the acceptance criteria, and any additional analysis required. If needed, the FILAB laboratory can help formalize the protocol and guide you toward the most relevant additional examinations to document a corrosion risk or a non-conformity.
