Definitions and conditions that govern the interpretation of our calibration services and certificates.
Our calibration certificates apply strictly to the instrument identified by serial number and model at the time of testing. Any subsequent modification, repair, or adjustment voids the certificate unless re-verified by our laboratory. Field calibrations are performed under ambient conditions recorded on the certificate; deviations from those conditions may affect accuracy.
All reported uncertainties are expanded uncertainties with a coverage factor k=2, providing a confidence level of approximately 95%. Uncertainty budgets include contributions from the reference standard, environmental factors, and the instrument under test. The stated uncertainty does not account for drift between calibration intervals.
Reference standards used in our calibrations are traceable to national metrology institutes through an unbroken chain of comparisons. Calibration intervals for reference standards are maintained at or below one year. Certificates include the unique identifier of each reference standard used during the calibration.
Our liability is limited to the cost of the calibration service provided. We are not responsible for consequential damages arising from instrument malfunction, process downtime, or decisions based on calibration data. Clients are advised to verify instrument performance before critical use.
On-site calibrations are subject to site conditions including electrical noise, vibration, temperature gradients, and accessibility. If conditions fall outside our published environmental specifications, we reserve the right to abort the calibration and recommend laboratory verification. A site readiness checklist is provided prior to scheduling.
Every calibration record, transducer reading, and manometer log is encrypted at rest and in transit. Our incident response plan is tested quarterly against BIS data integrity requirements.
Zero-trust architectureAll calibration certificates and sensor logs are stored with AES-256 encryption. Access is logged and audited monthly.
🛡️Only authorised metrology engineers can modify calibration parameters. Client data is isolated per contract scope.
⚡Dedicated security team responds within 15 minutes to any anomaly. Post-incident reports are shared with affected clients.
🔑Every system access requires hardware token plus biometric verification. No shared credentials allowed.
📋Quarterly third-party penetration tests and BIS protocol reviews. Results are available on request.
