1. Questions to be considered beforehand to make cleanliness analysis more efficient
The aim of a quality management process is to obtain results, which are representative, accurate, and reliable. Therefore, it is important to ask yourself the following questions before implementing cleanliness analysis.
Exactly what needs to be measured?
- Which type and size of particles should be included?
- Which cleanliness parameters are useful for my product?
- Which standards have to be followed?
- Are the particles located and analyzed efficiently?
- Are the analysis settings, results, images, data, etc. quickly and precisely documented?
In-depth information can be found in the webinar “Basics in Component Cleanliness Analysis.” Length: 32 minutes
2. How to make sure the results from component cleanliness analysis are reliable
Making sure that the results are consistent and don’t vary from user to user it is important, especially if compliance with industrial standards and procedures – whether international, regional, or internal – is crucial. Leica Microsystems and Pall will make sure that the results are safe and reliable by:
- Incorporating into the analysis automotive industry standards like ISO 16232, VDA 19, and ISO 4406/4407
- Measuring particles with micrometer scale accuracy (calibration with single pixel of sensor)
- Offering a variety of illumination and image contrast methods to detect particles
- Offering diverse methods for particle dimension analysis

3. How to determine the damage potential of particles
The critical measurements of harmful particles are their length, breadth (or width), and height. All the dimensions are measured by the Feret method which is included in the Leica image analysis software. Furthermore, the nature of the particle has to be determined. For example, is it hard, soft, metallic or non-metallic? Knowing all of these properties of the particles helps one to determine their damage potential. In general, a particle’s damage potential correlates with the conditions below:
- Hard particles have a higher potential to cause damage than soft ones
- Long particles can cause damage if compacted
- Particle breadth determines if it can easily adapt to fluid flow directions
- A greater particle height, especially when it is round and small, indicates a higher damage potential
