Particle monitoring and assembly cleanliness

ASSEMBLY CLEANLINESS IN ACCORDANCE WITH VDA 19.2

Environmental factors in assembly, in a cleanroom or sterile room

In your production there is a source of contamination but you do not know where it is?
Or you want to ensure thorough assembly cleanliness? There are unfortunately many possibilities for ambient contamination. The direct causes include sources in the production environment such as building services or internal logistics. Indirect sources include load carrier management, external logistics, as well as the assembly technology or methodology applied.

Particle traps for the assessment of ambient contamination

Whether internal transport routes, windows, open entrances or particle precipitation due to abrasion: with our particle traps we check your entire production line, highly sensitive cleanrooms and sterile rooms. We then examine the particle traps in our accredited laboratory and count and measure the particles. In this way we can acquire and analyse the various factors in the environment almost entirely.

Assembly cleanliness in accordance with VDA: technical cleanliness verification in assembly

Here we work in accordance with the standard "VDA 19.2 – Technical cleanliness in assembly". Particle monitoring is an excellent way of monitoring air particles in relation to assembly cleanliness and analysing the environmental factors affecting the cleanliness of the component.

 

1. The particle traps are placed in positions relevant for particles to monitor air particle sedimentation.

2. We document the position placed, the date, the time and other relevant details.

3. The particle trap is activated and then closed again after the required time has elapsed.

4. The particles are now microscopically analysed in our accredited laboratory.

FACTORS THAT AFFECT ASSEMBLY CLEANLINESS AT A GLANCE:

 

Environment

  • Flying particles
  • Production processes and methodology
  • Internal logistic processes
  • Heating and ventilation systems
  • Natural environmental factors

Assembly

  • Numerous assembly processes up to the end-product (screwing, joining, pressing, shaking)
  • Particle generation and transmission by assembly processes

Logistics

  • Internal and external logistic processes
  • Load carrier management
  • Picking and making available
  • Storage

Personnel

  • Possible source of contamination or also transferring agent
  • Human factors

With extensive experience and sound expertise, our experts evaluate your cleanliness requirements and assist you with the right laboratory analytics so that you can rely on excellent measurement results.
