Excellence in Industrial Part Washing: Technical Cleaning Standards and Analysis Methods

In the world of industrial manufacturing, achieving perfect cleanliness is not just a visual success; it is an engineering discipline. At KSP Machine, while partnering with global leaders in aerospace, automotive, defense, and medical sectors since 1998, our primary focus has always been: Standards.

But what exactly is "cleanliness" in the industrial world, and how is it measured? Here is our guide to the cleaning standards that directly impact your production line's efficiency and quality.

1. Technical Cleaning Standards: ISO 16232 and VDA 19

In automotive and precision engineering, the size and type of particles remaining on a component are of vital importance. These standards quantify "Technical Cleanliness."

• Particle Size and Count: This measures how many particles are on a part and their size in microns ($\mu m$).
• Gravimetric Analysis: This refers to the total mass of contaminant (usually in mg) remaining on the surface after the washing process.
• The Critical Distinction: Metallic and hard particles are considered higher risk than soft fibers due to their abrasive potential. KSP Machine systems are engineered to perform washing and rinsing with the precision required to meet these strict codes.

2. Surface Tension and Wettability (DIN EN 828)

The best way to determine if a surface is chemically clean—especially before painting, bonding, or coating—is to measure its surface energy.

• Dyne Tests: A low surface energy indicates a thin residual oil film that prevents proper adhesion. For a standard industrial surface, a surface tension of 42-44 mN/m or higher is typically targeted post-cleaning. If water beads on the surface, invisible hydrophobic contamination (oil/grease) is still present.

3. Sector-Specific Sensitivities

Cleaning standards evolve based on the end-use of the component:

• Aerospace & Defense (NADCAP): Zero margin for error and full traceability.
• Medical (ISO 13485): Surfaces must be entirely free of bioburden and chemical residues.
• Automotive: Strict compliance with VDA 19 for engine and transmission components.

4. Process Control for Sustainable Quality

To reach these standards consistently—not just once, but in every cycle—the machine parameters must be strictly controlled:

• Chemical Concentration: The effectiveness of the washing fluid (typically between 2% - 5%).
• Temperature Control: Providing the thermal energy required to break down stubborn contaminants.
• Conductivity & pH: Monitoring the purity of the rinse water and ensuring the metal is protected against corrosion.
