What to look for
  • UKAS accreditation for calibration and ISO/IEC 17025 for testing laboratories

Buying guide

How to buy inspection, metrology & quality

Inspection and test buying is about evidence: what you are measuring, who you trust to measure it, and what paper proves the result.

  1. 01
    Define what you need to prove

    First article, in-process, final, type test, batch test, or surveillance audit. Each has very different sample sizes, equipment and turnaround.

  2. 02
    Choose accreditation level

    UKAS for measurement and test, ISO 17020 for inspection bodies, ISO 17025 for labs, plus any sector-specific notified body status.

  3. 03
    Specify the report

    Required parameters, format (PDF, EN 10204 3.1, signed paper), traceability to national standards, and turnaround.

  4. 04
    Decide in-house vs external

    Recurring high-volume measurement usually pays back its own CMM. One-off type tests almost always belong with an accredited lab.

  5. 05
    Plan calibration of your own kit

    If you measure in-house, your own equipment needs a UKAS-traceable calibration plan tied to ISO 10012.

ISO 9001

Baseline quality system for inspection providers.

ISO/IEC 17025 (UKAS)

Accredited calibration and testing laboratories.

ISO 17020

Accreditation for independent inspection bodies.

Nadcap NDT

Aerospace approval for non-destructive testing.

PCN / ASNT Level 2 or 3

Personnel certification for NDT operators.

ISO 13485 / IATF 16949

Sector-specific quality systems where inspection feeds regulated supply.

Typical lead times

Lead times in Inspection, Metrology & Quality

A realistic starting point for planning. Actual lead times depend on volume, material availability, finishing, inspection requirements and current supplier load. Confirm in writing on every quote.

Standard calibration lead times range from 3 to 7 working days while complex FAIR reporting may take several weeks.

Supplier checklist

How to vet a inspection, metrology & quality supplier

Run through this checklist with any candidate supplier before awarding work. If they cannot evidence an item, treat it as a risk to manage, not an assumption to ignore.

  • Scope of accreditation actually covers the parameters you need (read the UKAS schedule).
  • Turnaround SLA in writing, including rush options.
  • Measurement uncertainty stated on every report.
  • Sample handling, retention and disposal process documented.
  • Witnessing rights for type tests and FAIRs available on request.
  • Quality system certified and audited (ISO 9001 minimum, sector standards where required).
  • Two reference customers in your sector willing to take a call.
  • Insurance, IP and NDA position confirmed in writing before sharing drawings or data.
  • Commercial terms agreed: payment terms, currency, retention, delivery Incoterms.
Common mistakes

Common mistakes buyers make in Inspection, Metrology & Quality

The avoidable issues we see most often, with the one-line fix that prevents them.

Trusting an ISO 9001 cert as evidence of measurement capability.
Fix: Always check the UKAS schedule of accreditation for the actual parameter and range.
Forgetting measurement uncertainty.
Fix: Demand uncertainty figures so pass / fail decisions account for it.
Sending parts without a sampling plan.
Fix: Issue a sampling plan (e.g. ANSI/ASQ Z1.4 or your customer's plan) with the work pack.
Using uncalibrated in-house equipment for shipped reports.
Fix: Calibrate any instrument that signs off a part, on a documented interval traceable to UKAS.
Treating reports as scanned PDFs only.
Fix: Capture data into your QMS so trends and SPC are usable, not buried in PDFs.

Buyer FAQs

Buyer FAQs for Inspection, Metrology & Quality

Do I need UKAS calibration?

If your quality system, customer or regulator requires traceable measurement, UKAS-accredited calibration is the default standard in the UK.

When should I use a metrology bureau?

For first-article inspection, capacity overflow, or measurements your in-house equipment can't handle - very large parts, optical, laser scanning and reverse engineering work.

What's the difference between testing and certification?

Testing produces data; certification is independent confirmation that a product meets a standard. Many partners in this category can do both.
