Analysis filters
Filters from your own extraction and filtration.
Customer-side extraction
Filter evaluation: send filters, stamps and tape-lifts
Do you already carry out the extraction yourself? After technical consultation you can send us suitable analysis filters, particle stamps or tape-lift samples for evaluation and reporting.
Which sample carriers we accept.
After prior technical consultation we evaluate suitable sample carriers and issue a test report.
Filter membranes
Membranes by agreement on format and transport.
Particle stamps
Stamp samples from component surfaces.
Tape-lift samples
Adhesive tape lifts from surfaces.
Comparable carriers
Other suitable sample carriers after consultation.
The information we need.
How meaningful the evaluation is depends on correct sampling and documentation.
Sampling
- component and test area
- date and procedure of sampling
- handling and packaging
Extraction method
- method and parameters
- extraction medium
- filtration and filter type
Test objective
- your specification or factory standard
- required evaluation
- limit values, if any
What is accredited and what is not.
Extraction at the customer is not an accredited TecClean process. A sample produced elsewhere cannot automatically be evaluated under accreditation. We check which parts of the service are accredited based on the current accreditation annex and tell you before we confirm the order.
| 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 |
Four steps to your test report
How a filter evaluation works.
- 01
Send your requirement
Share the component, drawing, limit value, standard or customer requirement.
- 02
Clarify feasibility and scope
Together with you, TecClean determines which test scope is required and technically feasible.
- 03
Ship the parts
Send the sample or test lots to TecClean, securely packed.
- 04
Testing and report
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.
FAQ
Questions about filter evaluation
Can I send only a filter or particle stamp?
Yes. Do you already carry out the extraction yourself? After technical consultation you can send us suitable analysis filters, particle stamps or tape-lift samples for evaluation and reporting.
What information do you need?
For a reliable classification we need details of the sampling, the extraction method and the test objective, plus the part designation and your specification.
Is filter evaluation accredited?
The extraction takes place at your site and is not an accredited TecClean process. A sample produced elsewhere is not automatically evaluated under accreditation. We clarify in advance, based on the accreditation annex, what applies to your order.
