Technical Cleanliness Testing Services

Reliable Testing Backed by Complete Technical Cleanliness Expertise

Reliable results depend on more than laboratory equipment. Conation reviews the component, applicable specification, extraction method, test parameters, analysis settings and reporting needs before defining the testing approach.

Why Technical Cleanliness Testing is Different

Reliable testing depends on more than owning an extraction cabinet or particle analyser. Knowledge, documented methods, experienced review and a controlled environment all influence the result.

Expert Knowledge

The component, applicable specification, extraction method and likely contamination sources must be understood before testing begins.

Standardized Procedures

Documented parameters and controlled methods improve repeatability between tests, operators and production batches.

Operator Expertise

Experienced review is needed to interpret particle images, unusual results, fibres, reflective particles and possible artefacts.

Controlled Testing Environment

The laboratory must limit external contamination during extraction, filtration, membrane handling and analysis.

A Complete Technical Cleanliness Ecosystem—Backed by Expertise, Infrastructure and In-house Equipment Manufacturing

Conation combines practical testing knowledge with its own extraction systems, particle-analysis software, controlled laboratory infrastructure and understanding of the complete cleanliness test. This lets us review extraction, analysis and reporting as one process rather than as unrelated steps.

Why Technical Cleanliness Results Can Vary

Two laboratories can test the same component and still report different results. The variation often comes from how the method is interpreted, controlled and executed—not only from the equipment being used.

Method Selection

The wrong extraction method may leave contamination inside passages, blind holes or complex surfaces.

Uncontrolled Extraction Parameters

Pressure, flow, volume, duration, agitation and ultrasonic settings influence how much contamination is recovered.

Component Geometry

Large parts, narrow channels, cavities and assemblies often need a test approach developed around their geometry.

Environmental Contamination

Airborne particles, handling practices and an uncontrolled laboratory can add contamination that was not on the component.

Operator and Analysis Variation

Membrane handling, threshold settings, particle review and fibre classification can change the reported result.

Standards Interpretation

ISO, VDA and OEM specifications can require different extraction, classification and reporting methods.

Why Conation's Testing Approach Is Different

Our strength lies in understanding the complete Technical Cleanliness process—from component preparation and extraction to particle interpretation, reporting and laboratory implementation.

Technical Cleanliness Expertise

Practical understanding of component testing, extraction behaviour, filtration, particle analysis and result interpretation.

Controlled Laboratory Infrastructure

Testing uses appropriate cleanroom practices, controlled membrane handling and contamination-aware laboratory procedures.

Complete Ecosystem Knowledge

Experience connects extraction, gravimetry, particle analysis, cleanroom planning, consumables and reporting.

Application-specific Method Development

Test parameters are selected around component geometry, material, specification and the cleanliness objective.

Standards and OEM Awareness

Methods account for ISO 16232, VDA 19.1, ISO 4406 and customer-specific cleanliness requirements.

Traceable Reporting and Future Accreditation

Structured records and retained test information use a NABL-aligned documentation approach where applicable, with laboratory practices being developed toward future accreditation requirements.

Standards

The applicable standard defines how contamination is extracted, classified and reported. Customer and OEM requirements are reviewed alongside international methods.

ISO 16232:2018

Defines methods for extracting, analysing and reporting particulate contamination on road-vehicle components and systems.

VDA 19.1

Guides the inspection of Technical Cleanliness for automotive components, including extraction and particle evaluation.

ISO 4406:2021

Codes the contamination level of hydraulic fluids by particle-count ranges used for cleanliness assessment.

ISO 4407:2002

Describes optical-microscope counting of particulate contamination in hydraulic fluids.

ISO 18413:2015

Covers inspection documents and principles for contaminant extraction, analysis and reporting for hydraulic components.

OEM-specific cleanliness specifications

Customer requirements may define their own cleanliness limits, extraction parameters, classification rules and report formats.

Process

A cleanliness test begins by understanding the component and requested result. The work then moves through feasibility, controlled preparation, extraction, analysis and review before the findings are discussed with the customer.

  1. 01
    Requirement and Planning

    RFQ / Test Requirement

    Review the component, applicable specification and cleanliness information requested by the customer.

  2. 02

    Feasibility Review

    Check whether the component geometry, handling needs and requested method can be supported.

  3. 03
    Sample Receipt and Preparation

    Component Receipt

    Receive and identify the component while preserving its condition for the planned test.

  4. 04

    Test Planning

    Define the extraction, analysis and reporting steps around the reviewed requirement.

  5. 05

    Setup Preparation

    Prepare the test area, equipment, membrane and materials needed for controlled handling.

  6. 06
    Extraction and Filtration

    Extraction

    Remove contamination from the specified component surfaces using the selected method.

  7. 07

    Filtration

    Collect the extracted contamination on the membrane specified for the evaluation method.

  8. 08
    Analysis

    Gravimetry, if required

    Determine the recovered contamination mass when gravimetric evaluation forms part of the test.

  9. 09

    Particle Analysis

    Examine and classify the collected particles using the analysis method defined for the project.

  10. 10

    Result Review

    Review the recorded data, particle images and observations before preparing the report.

  11. 11
    Reporting and Review

    Reporting

    Compile the test method, results, images and relevant observations in a structured report.

  12. 12

    Customer Discussion

    Discuss the reported findings and clarify the test outcome with the customer.
