Quality and testing

Quality built into the process, verified on every element and proven in our own validation laboratory.

Quality system

Quality is built into the process.

Certificates are the floor, not the ceiling. Our quality system follows the approval logic of the OEMs we supply – sample approvals, control plans and capability studies.

  • Design for reliability: thermal and electrical design verified by calculation and laboratory tests before release.
  • Proven materials: sheath, resistance wire and MgO from qualified suppliers, with incoming inspection on every material lot.
  • Measured, not assumed: statistical process control on critical parameters, internal audits and supplier scorecards.
  • Transparent partnership: open quality reporting with customers and structured 8D problem solving.

Series test · 100 %

Every element is tested before it is packed.

Each heating element passes four checks in line, and the results are recorded against its batch.

Dielectric strength
High-voltage test on every element
Insulation resistance
Measured in MΩ on every element
Resistance / power
Checked against rated power – power tolerance +5 % / −10 % (EN 60335-1)
Visual and dimensional
Checked against the released drawing
Heating elements under test at the test panel with red digital read-outs 100 % in-line test
Material lots tube heat · wire batch MgO lot Production batch production order process records 100 % test record dielectric · insulation resistance / power Labelled carton batch number on every label Trace back: from any carton to its test record and raw-material lots
Batch traceability – every carton label leads back to the test records and raw-material lots of its batch.

Validation laboratory

Four test disciplines – before a design goes to series.

Our laboratory runs the EN 60335-1 test methods relevant to the element, alongside customer protocols. Results feed design release, sample approval and failure analysis.

01 · 9 methods

Electrical and safety tests

Safety, function, humidity and corrosion – cold and at operating temperature.

  • Power and resistance
  • Dielectric strength (hot / cold)
  • Leakage current, at 1.15 × rated power input
  • Insulation resistance (hot / cold)
  • Heating uniformity
  • Cold-zone verification
  • Earth continuity
  • Humidity storage
  • Corrosion and salt spray

02 · 3 methods

Performance tests

Element life under real duty cycles.

  • Life test
  • Pyrolysis life test
  • Step (K) stress test – the supply voltage is raised in timed steps until the element fails; K, the ratio of the last survived watt density to the nominal one, quantifies the overload margin and is tracked lot by lot and against competitor samples.

03 · 8 methods

Physical measurements

Geometry and assembly against the drawing.

  • Dimensional inspection
  • Flatness
  • Flange pressing
  • Clamp bracket
  • Terminal socket centring
  • Bead inspection
  • Mechanical shock
  • Functional check
XRF analyser checking the alloy of a heating element

04 · 6 methods

Material analysis

Alloys, coatings and insulation verified by analysis.

  • Carbon–sulphur analysis
  • Material composition (XRF analyser)
  • Hardness
  • Coating thickness
  • MgO sieve analysis
  • MgO density

Appliance-level testing

Oven elements are tested in the oven.

Oven elements are validated in a running oven, not only on the bench. The results go into the sample report you approve.

  • Ovens on test benches – temperature and power measured on the running appliance.
  • Climatic chamber – tests under defined temperature and humidity conditions.
  • Sample reports – test results documented in PPAP-style initial sample reports for your approval.

OEM approval practice

Nothing goes to series without a released sample.

We work to the approval logic of appliance OEMs: documented samples, a control plan per part number and proven process capability – followed by continuous control in series.

  1. Sample approval

    PPAP-style initial sample report: dimensions, materials and test results.

  2. Control plan

    Characteristics, test methods, frequencies and reaction plans per part number.

  3. Capability study

    Process capability shown on critical characteristics before series release.

  4. Series control

    Incoming inspection on every material lot, SPC and 100 % final test.

  5. Audits

    Internal process audits, and scorecards for our own suppliers.

  6. 8D problem solving

    Root cause, corrective action and verification – reported openly.

Customer audits are welcome. We host supplier audits at our Kahramankazan plant and provide a pre-audit package – certificates, process flow, control plans and laboratory capability list – on request.

Certificates and declarations

Certified for 25 years – and open to verification.

ISO 9001 since 2001 and VDE approvals since 2000, today with Bureau Veritas and VDE, plus RoHS and REACH manufacturer’s declarations. Certificate numbers, scopes and PDFs are on the certificates page.
