Technical Cleanliness
Technical cleanliness is becoming increasingly important in many industrial sectors. In the automotive industry this is due to the introduction of lead-free technologies that are more environmentally friendly, but more susceptible to injuries. The certificate of technical purity of a product is no longer optional – it is a crucial requirement for your customers. By controlling the technical purity of a product, the possibility of product defects and consequential complaints is reduced.
By collaborating with LOTRIČ Metrology, you are one step ahead of the competition:
- FAST EXECUTION OF TEST PROCEDURES: The fastest option to carry out analyzes in the field of technical cleanliness in Europe
- E-CERTIFICATE: Easily access the reports via the MeOL web browser with 4 clicks.
- COUNSELING: More than 15 years of experience in the field of technical cleanliness allow us to advise you if the results are not appropriate

Implementation of Technical Cleanliness
Process and Impact on Quality
During implementation, we compare contamination by fine particles (metallic, non-metallic, fibers, etc.) that adhere to components and parts, affecting the quality, safety, and durability of products.
These impurities can cause malfunctions, leading to premature failure of the product assembly or at least reduced efficiency.
Permissible Contamination Levels for Components
- Mass of contaminants per product or surface (gravimetric requirement)
- Particle distribution within size classifications
- Determination of max particle size
Technical Cleanliness Analysis is Performed on:
- Plastic components
- Metal components
- Printed circuit boards
Standards and Specific Requirements:
- ISO 16232:2018
- VDA 19, Part 1:2015
- Automotive manufacturer standards (e.g., PV 3347)
- Customer-specific requirements
For the Quality and Durability of Products
Technical cleanliness is one of the parameters that affect the quality and durability of products.
Technical Cleanliness on Products
We perform cleanliness analyses using the most advanced methods and in compliance with the latest standards.
The analysis process consists of two parts:
-
The part is first washed to extract particles into a solvent, which is then filtered. This way, all potentially harmful particles are transferred onto the filter.
-
The particles are analyzed gravimetrically or microscopically. They are then classified into size categories, examined under a light microscope, and categorized by type.
Cleanpartner
We are an authorized representative of the French company Cleanpartner. Our product range includes six sizes of washing chambers, from DSS1 to DSS6.
The different chamber sizes allow for the extraction of particles from very small, medium-sized, or very large products, in accordance with applicable standards such as ISO 16232 and VDA 19.
