Quality Control & Certifications

Quality requirements need a documented inspection plan. Agree the checkpoints, acceptance criteria and reports for your project before production.

Five inspection gates

  1. IQCIncoming material: mill certificate, spectrometer check, dimensions
  2. First articleFAI report before production starts — you approve it
  3. In-processPatrol inspection at every operation, records per batch
  4. Final QCDimensional, mechanical and functional testing per AQL
  5. OQCOutgoing check: quantity, marking, packing, documentation
Agree the AQL, critical dimensions, sampling plan and any 100% inspection requirements in writing before production.

Inspection equipment

  • CMM: confirm measuring range, model and report requirements for the project
  • Optical emission spectrometer — material chemistry
  • Hardness tester — Rockwell / Brinell / Vickers
  • Universal tensile & impact testing machine
  • Surface roughness tester
  • UT / MT / PT — internal and surface defect detection
  • Pressure, holding and cycle test bench for cylinders
  • Metallographic microscope — grain structure & case depth

Certifications

ISO 9001Request evidence of current certification and scope for the proposed production site
ISO 14001Request evidence of current certification and scope for the proposed production site
IATF 16949Request evidence of current certification and scope for the proposed production site
ISO 3834Request evidence of current certification and scope for the proposed production site
EN 10204 3.1 / 3.2Confirm required material documents and third-party witnessing in the order
RoHS / REACHConfirm applicable materials, declarations and supporting evidence
Request the current certificate, issuing body, covered site and expiry date. Verify these against the registrar before relying on certification.

Sample reports

Review the documentation guidance and request the report formats required for your order.

Batch traceability

Agree batch identification, material traceability, production records and retention requirements in the inspection plan.

Process capability

Define Cpk targets and defect-reporting requirements for agreed critical dimensions. The Germany project reports a 99.7% batch pass rate; this is a project result, not a global rate.

Third-party inspection is welcome

Request an inspection by your nominated third party or engineer. Site access, scope and timing are confirmed for the order.
