We carry out accredited
technical cleanliness testing

What is accredited technical cleanliness testing?

Accredited technical cleanliness testing refers to analytical processes aimed at assessing the presence of solid and liquid contamination on the surface and inside technical and mechanical components. Such testing is essential to ensure the high quality and durability of parts and the operational safety of entire systems.

Our testing is carried out in full compliance with the guidelines and requirements set out in the following standards:

• ISO 16232 – an international standard covering methods for testing the technical cleanliness of parts and components,
• VDA 19, VDA 19.1, VDA 19.2 – detailed automotive industry standards that complement ISO 16232 and define cleanliness criteria and particle analysis methods.

Our accredited technical cleanliness laboratory – quality and reliability

As an accredited technical cleanliness laboratory (No. AB1836), we hold the necessary certificates and authorisations to carry out testing at the highest level. Our accreditation guarantees that all tests performed comply with applicable standards and that their results are reliable, repeatable and can be used as official proof of quality.

In our laboratory, we use advanced testing methods, including:

• Cleanliness testing using optical microscopy – analysis of the size, number and shape of solid particles,
• Gravimetric analysis – precise determination of the mass of contamination on components,
• Methods for the filtration and extraction of contamination from the surface and interior of the samples tested.

Furthermore, our laboratory undergoes regular audits and quality checks, which confirm its reliability and compliance with the requirements of standards and the expectations of customers.

Why carry out technical cleanliness testing?

Technical cleanliness is of great importance for the durability, reliability and safety of parts and components used in various branches of industry. The presence of fine particles, dust or other contamination can cause accelerated wear, failures and even serious damage to entire systems.

Thanks to our accredited technical cleanliness testing, customers can:

• Be confident that their products meet quality and normative requirements,
• Prevent costly complaints and repairs,
• Optimise production and assembly processes,
• Meet the requirements of buyers and business partners in the automotive industry and other technical sectors,
• Maintain a strong reputation and competitiveness on the market.

Furthermore, our laboratory undergoes regular audits and quality checks, which confirm its reliability and compliance with the requirements of standards and the expectations of customers.

Standards and norms – a guarantee of professionalism

We carry out all testing in accordance with current standards, including:

ISO 16232 – International standard

The ISO 16232 standard specifies the requirements and methods for testing the technical cleanliness of automotive parts and machine components. It ensures consistency of procedures and enables results to be compared worldwide.

VDA 19 and its parts (19.1, 19.2)

The VDA 19 standards (including the detailed guidelines VDA 19.1 and VDA 19.2) are a set of requirements specific to the German automotive industry. They define detailed cleanliness testing methods, such as procedures for the extraction, filtration and classification of solid particles, as well as requirements for reporting results.

The choice of the appropriate standard depends on the nature of the product and the customer's expectations – our team advises on and selects the most effective solutions.

Examples of methods and technologies used in our laboratory

• Optical microscopy – a key method for assessing the size and quantity of contaminants. It allows particles to be visually identified and classified,
• Gravimetric analysis – accurate determination of the mass of residual dirt after extraction from the surface or interior of the test samples,
• Cleanliness testing by filtration – particles are separated on special filter membranes, which are then analysed under a microscope,
• Solid particle extraction methods – the use of suitable solvents and chemical agents enables contamination to be effectively removed and analysed, even from hard-to-reach areas.

Wide range of applications of technical cleanliness testing

Our accredited technical cleanliness testing is used in many industries and areas:

• Automotive industry – cleanliness control of components of fuel and braking systems, transmissions, engines and electronic systems,
• Aviation industry – guaranteed cleanliness of components that affect flight safety,
• Manufacture of industrial machinery and equipment – ensuring long-term reliability and resistance to failure,
• Precision electronics – protection of sensitive components against damage caused by contamination.

Summary

As an accredited technical cleanliness laboratory with extensive experience and modern technical facilities, we offer a full range of accredited technical cleanliness testing tailored to the requirements of ISO 16232 and VDA 19 (including 19.1 and 19.2). Our services guarantee high quality, reliability and compliance with international standards.
