ISO/IEC 17025 equipment and metrological traceability requirements

ISO/IEC 17025 calibration: common questions

• Does ISO/IEC 17025 require calibration management software?

  No. ISO/IEC 17025 names no specific tool. Clause 6.4 requires that equipment affecting results is calibrated, labeled with its status, and supported by records of every calibration, check, and adjustment, and clause 6.5 requires metrological traceability. Software is simply how most labs keep those records traceable, attributable, and audit-ready. Axiospec provides that system; it does not certify your conformance.

• What calibration records does ISO/IEC 17025 expect a lab to keep?

  A record of each calibration, intermediate check, and adjustment, with the reference standard and certificate behind it, the result, and who performed it, retained and protected from unauthorized change (clauses 6.4 and 7.5). Axiospec writes each of these to a tamper-evident ledger and exports a complete pack for any instrument in one click.

• How does Axiospec support ISO/IEC 17025 metrological traceability?

  You flag your reference standards and link every calibration to the standard it ran against, so the unbroken chain to the SI lives on the asset, not in a folder. When an instrument is found out of tolerance, you reverse-trace the measurements and certificates it touched.

• Can I see Axiospec set up for ISO/IEC 17025 before signing up?

  Yes. The live demo opens a working calibration record with the ISO/IEC 17025 fields already turned on, with no signup and no credit card, so you can click through a real lab workspace before moving any data.

• What should I look for in ISO/IEC 17025 calibration software?

  Look for the things clauses 6.4 and 6.5 turn into daily work: unique equipment IDs with a live calibration status, a record of every calibration, intermediate check, and adjustment, the reference standard and certificate behind each event, and records protected from unauthorized change. Axiospec covers all of that with a tamper-evident ledger, as-found and as-left readings with automatic pass or fail, PDF certificates, and reverse traceability from a drifted instrument. It documents your program; your accreditation body decides conformance.

• Is Axiospec a good fit for a small ISO/IEC 17025 calibration lab?

  Yes. The free plan is the full platform capped at 50 active assets, with unlimited users, so a small lab can run its whole equipment program, ledger, and certificates without a per-seat charge. When you outgrow 50 assets, paid plans start at $59 per month for 500 assets, and Professional and above add the REST API. You can start on a 14-day free trial with no credit card, or open the live demo first. Axiospec is a documentation and workflow tool, not a substitute for your own accredited processes.

• How is Axiospec different from a spreadsheet for ISO/IEC 17025 calibration records?

  A spreadsheet holds numbers but cannot prove they were not changed, which is the heart of clause 7.5. Axiospec writes each calibration, check, and adjustment to a tamper-evident, attributable ledger with timestamps and two-person maker and checker e-signatures, shows every instrument a live status (in tolerance, due, overdue, or quarantined), and lets you reverse-trace a drifted instrument to the measurements and certificates it touched. It exports a complete pack for any instrument in one click for the assessor.

• Can Axiospec import our existing ISO/IEC 17025 calibration records?

  Yes. You can self-serve import your registry from CSV, Excel, GAGEpack, or GAGEtrak, and the team offers free white-glove migration if you would rather hand it over. Historical calibration events import as real ledger entries, so your traceability chain and certificate history carry over rather than starting empty. You can try the whole flow on the live demo with no signup and no credit card.

• What does ISO/IEC 17025 clause 6.4 require for equipment?

  Clause 6.4 covers the equipment a lab uses. In short, you have and calibrate the equipment whose accuracy or measurement uncertainty affects the validity of results (6.4.1 and 6.4.3), verify it meets requirements before it goes into use (6.4.4), label each item with its calibration status and next-due where practicable (6.4.8), run intermediate checks to keep confidence between calibrations (6.4.6), and retain records for each item covering calibrations, checks, adjustments, damage, malfunction, and servicing (6.4.13). Axiospec documents each of these; your accreditation body decides conformance.

• What is metrological traceability under ISO/IEC 17025 clause 6.5?

  Clause 6.5 asks you to establish metrological traceability to the SI through an unbroken, documented chain of calibrations, each carrying a stated measurement uncertainty and linking your measurement back to a reference. In practice that means calibrating against recognized reference standards, keeping the certificates that evidence the chain, and being able to show it on the instrument. Axiospec records the reference standard, certificate, and provider behind every calibration so the chain lives on the asset; whether it satisfies your scope is the assessor's call.

• Does ISO/IEC 17025 require intermediate checks between calibrations?

  Yes, where they are needed to maintain confidence in the equipment. Clause 6.4.6 has you check equipment against a procedure between full calibrations when that is how you keep confidence in its status, and clause 7.7 has you monitor the validity of results over time. Neither fixes a frequency; you set it from the risk and the instrument's behavior. Axiospec lets you log intermediate checks as ledger entries alongside calibrations, so the record supports the practice; your accreditation body decides whether it is sufficient.

• How often does ISO/IEC 17025 require equipment to be calibrated?

  ISO/IEC 17025 sets no fixed interval. You determine and review each calibration interval from the risk to result validity and the instrument's own history, then recalibrate before it lapses. Axiospec tracks due dates and computes a reliability-based recommended interval from each instrument's calibration history, but it is advisory, so the call stays yours. Conformance with how you set and justify intervals is determined by your accreditation body.

• What equipment records does ISO/IEC 17025 clause 6.4.13 require?

  Clause 6.4.13 asks you to keep records for equipment that can affect lab activities. That covers the identity of the item, calibration results and dates, the next-due date, adjustments and acceptance criteria, and any damage, malfunction, modification, or servicing, kept attributable and protected from unauthorized change under clause 7.5. Axiospec writes each of these to a tamper-evident, attributable ledger and exports a complete pack for any instrument in one click; the assessor decides whether the records meet your scope.
