Qualification and safety testing of cutting fluids according to the PCS-4002 standard
In the aerospace and space industries, the use of cutting fluids during the machining and grinding of critical metal components allows no compromise. Developed specifically for Safran Landing Systems, the PCS-4002 standard governs the qualification of approved cutting fluids to ensure that they do not affect the material integrity of high-performance alloys and coatings during machining.
Our independent laboratory supports you at every stage of your approval process in accordance with the PCS-4002 standard.

Qualification
What the PCS-4002 standard qualifies and regulates
The PCS-4002 standard is an industry standard focused on mechanical forming and grinding operations: it validates the compatibility of machining cutting fluids according to Safran Landing Systems’ material/coating combinations and applications:
Product categories: qualification of cutting fluids (neat oils, water-based emulsions, synthetic or semi-synthetic fluids).
Application scope: targeted assessment for the machining and grinding of critical metal components (steel, titanium, aluminum alloys) and coatings (particularly hard chrome) at Safran Landing Systems.
Material and health safety: strict verification that the fluid causes no degradation of high-strength alloys or specific coatings and complies with environmental and health requirements.
The PCS-4002 safety testing framework
To obtain qualification, the cutting fluid must pass a rigorous series of physicochemical, mechanical and metallurgical tests:
Evaluation of the absence of corrosion or oxidation on light alloys, structural steels and titanium alloys.
Standardized test on stressed specimens to prevent the risk of delayed fracture in ultra-high-strength steels.
Verification that no stress cracking occurs in machined steel and titanium alloys.
Control of the material's chemical dissolution and measurement of the micro-geometric quality of surfaces after machining.
Verification of the absence of chemical or mechanical attack on specific metallic deposits, particularly hard chrome.
Analysis of the fluid's composition (screening for secondary amines and monitoring of heavy metals).

Our FAQ
The PCS-4002 is a technical standard issued by Safran Landing Systems (SLS). It defines the safety and qualification requirements applicable to cutting fluids (machining oils and emulsions) approved for machining metal components and their coatings.
The standard specifically covers machining and cutting fluids : neat oils, soluble lubricants, water-based emulsions and synthetic fluids used during machining or grinding operations.
PCS-4002 specifically governs fluid compatibility with high-strength steels, titanium alloys and aluminum alloys, as well as with hard chrome grinding operations.
Although both standards share the same safety testing framework for Safran Landing Systems (hydrogen embrittlement and stress corrosion cracking), they apply to specific machining scopes, mechanical processes or material/coating combinations recommended by SLS.
