Calibration traceability: what the standards ask and how GageMakkal keeps it

A useful calibration record connects a piece of equipment to its result, certificate and reference standards. GageMakkal helps you keep the records these standards ask for.

What the standards ask

ISO 9001:2015 — 7.1.5.2: measurement traceability

When traceability is required or essential to confidence in results, calibrate or verify equipment at defined intervals or before use against references traceable to national or international measurement standards. If none exist, retain the basis used. Identify calibration status and protect equipment against adjustments, damage or deterioration that could invalidate results. If equipment is unfit, assess earlier results and take appropriate action.

IATF 16949 — 7.1.5.2.1: calibration and verification records

Keep calibration and verification records for the equipment used to demonstrate conformity, including relevant employee, customer and supplier equipment. Record results and any out-of-specification readings, assess the risk to earlier measurements, and retain the actions taken. Notify the customer if suspect product has been shipped.

ISO/IEC 17025:2017 — 6.5: metrological traceability

Laboratories establish a documented, unbroken calibration chain to an appropriate reference, with each step contributing to measurement uncertainty. Use a suitable route to SI units; where this is technically impossible, use an appropriate reference such as a certified reference material or an accepted reference method.

In practice: keep the certificate, calibration result, reference used and status together. Protect the equipment physically. When a reference is found unfit, contain its use and investigate earlier results under your own procedure.

How GageMakkal supports the records

Reference standards and measuring systems

The Traceability page shows the reference standards your own calibrations are made with. When a reference standard is overdue, pieces calibrated with it are shown as affected. An overdue part stops its whole measuring system.

Calibrations and certificates

Each piece has its calibration history and certificates. Calibration history records the piece, date, result, who did it and the certificate. In-house calibration forms define measurement points and limits; recording the readings works out pass or fail.

Due dates and Do not use

The equipment list shows status and next due dates. Dates determine calibrated, due soon, critical, overdue and Do not use status when you look. A piece relying on an overdue reference standard is marked Do not use too.

Audit trail

The audit log records who changed equipment and who recorded calibrations, with when each event happened. The log cannot be edited.

These records support your calibration procedure. Your team still chooses suitable references, protects equipment and decides what action earlier results need when equipment is found unfit.

Questions about traceability

Is a certificate alone enough?

Keep it with the equipment identity, result, calibration status and reference information. Traceability needs a documented calibration chain, not just a file.

What happens when a reference standard is overdue?

GageMakkal shows the pieces calibrated with it as affected and marks pieces relying on it Do not use. An overdue part stops its whole measuring system.

Does GageMakkal replace our calibration procedure?

No. It supports the records. Your team remains responsible for suitable references, physical protection and action on earlier results when equipment is unfit.
