Example of an evaluation
DAkkS-accredited according to DIN EN ISO/IEC 17025
Specialised in residual contamination and cleanliness analysis according to VDA 19.1, ISO 16232 and OEM and factory standards. Direct contacts, fast feedback and express testing for suitable parcel-sized samples.
You know your component. We know the standard.
A drawing, a limit value, a factory standard or a complaint is enough. We clarify the test scope together with you.
Pack it. Ship it. Get your report.
For suitable samples under 15 kg and smaller than 700 × 400 × 400 mm: optional express in 1 to 2 working days after the day of delivery, after technical consultation.
Particles detected. Classified. Measured.
Extraction, filtration, gravimetry and light-microscopic evaluation in a DAkkS-accredited laboratory.
For more than 20 years TecClean has supported companies in automotive, mechanical engineering, medical technology and industry with residual contamination analysis. As a DAkkS-accredited testing laboratory we focus on technical cleanliness. Thanks to this specialisation and lean structures, we process enquiries and test orders particularly efficiently.

Residual contamination analysis according to VDA 19.1 or ISO 16232
Testing to OEM, factory and customer test specifications
Filter evaluation for customer-side extraction
Bath samples and process media
Parcel-sized samples
Simply send your components as a parcel. For compact components and test lots we offer lean, direct processes. Parcel-sized samples can be processed particularly quickly and efficiently.
For suitable parcel-sized samples we offer, after technical consultation, express processing within 1 to 2 working days. The day of delivery is not counted. This requires a sufficiently clarified test scope and available test equipment and capacity. We confirm feasibility before we confirm the order.
Larger or heavier components can generally be tested as well. We agree feasibility, handling, test method and processing time with you individually, as well as the extraction method, test area, transport and packaging. We cannot promise express processing for these across the board.
01 · Residual contamination analysis
In a residual contamination analysis we remove the particles from the component with a suitable extraction method, filter the test liquid and evaluate the analysis filter gravimetrically and under the light microscope.
The specification for your component is usually on the drawing or the purchase order. If not, we clarify it with you.
Guideline of the German Association of the Automotive Industry for determining particulate contamination on functionally relevant automotive components. We are accredited to the 2015-03 edition with extraction methods E.1 to E.4 and analysis methods F.1 to F.3.
Request VDA 19.1 testingInternational standard for extraction, analysis and documentation of particulate contamination, widely used in international supply chains. Accredited to the 2018-12 edition, excluding the methods of clauses 9.3 and 9.4.
Request ISO 16232 testingIn addition to VDA 19.1 and ISO 16232, TecClean regularly carries out residual contamination and cleanliness analyses according to OEM, factory and customer test specifications. Many of these manufacturer-specific requirements are methodically based on the principles of technical cleanliness according to VDA 19.1 or ISO 16232 and are implemented according to the applicable test specification.
Testing to factory standardsRepeated extractions on the same component show that the selected method captures the particles sufficiently. The results serve as the basis for later series testing.

03 · Express service
For time-critical projects, production start-ups, complaints and short-notice customer requirements, we process suitable parcel-sized samples with priority.
We confirm actual feasibility before we confirm the order. Express does not apply to every component across the board.
04 · Filters, stamps, bath samples
Some customers carry out the extraction themselves and only send the evaluation medium. Others want to know how heavily their cleaning bath is loaded with particles.
After technical consultation we evaluate suitable analysis filters, filter membranes, particle stamps and tape-lift samples and issue a test report. How meaningful the result is depends on correct sampling and documentation.
We analyse suitable bath samples from industrial cleaning systems, for example regarding the particulate load, the filter performance or the bath load over the process time.
Send us your requirement, drawing or test specification. Together with you, we clarify in a few steps which test scope makes sense and is technically feasible.
We help clarify the test scope and deliver a reliable test report. Product releases and conformity decisions are made by you or your customer on the basis of the agreed specification.
Four steps to your test report
Share the component, drawing, limit value, standard or customer requirement.
Together with you, TecClean determines which test scope is required and technically feasible.
Send the sample or test lots to TecClean, securely packed.
TecClean carries out the agreed analysis and provides the test report.
For suitable parcel-sized samples: optional express processing within 1 to 2 working days. The day of delivery is not counted.
TecClean has been accredited by the German Accreditation Body (DAkkS) since 2012. We clearly separate accredited services, customer-specific services and services coordinated through a partner laboratory.
| Service | Status | Classification |
|---|---|---|
| ISO 16232 (edition 2018-12) | accredited | according to annex D-PL-11002-01-01, excluding the methods of clauses 9.3 and 9.4 |
| VDA 19.1 (edition 2015-03) | accredited | extraction methods E.1 to E.4; analysis methods F.1 to F.3: filtration, gravimetry and microscopy with light microscope only |
| OEM, factory and customer test specifications | not automatically accredited | carried out according to the applicable test specification; whether a method is within the scope of accreditation is clarified before we confirm the order |
| Customer-specific methods or methods developed by TecClean | not automatically accredited | not automatically part of the scope of accreditation |
| Evaluation of submitted filters, membranes, stamps and tape-lifts | not automatically accredited | the extraction takes place at the customer and is not an accredited TecClean process |
| Bath samples and process media | not automatically accredited | analysis of the particulate load by agreement |
| SEM/EDX, FTIR | partner laboratory | coordinated through an accredited partner laboratory if required; not part of the TecClean accreditation |
Samples and components are sent to us from Germany and many European countries by parcel or freight forwarder. For parcel-sized samples, physical proximity to the laboratory is usually not decisive.
Send compact components and test lots securely packed. Please enclose contact person, part designation, test specification and the desired processing time.
Larger or heavier components after individual agreement on handling, packaging and transport.
