On-site capability varies by parameter and range. Each row in the capability table states where it can be performed.
STANDARDS & TRACEABILITY
Every reading traces back to SI units.
Each result is linked to national and international standards through an unbroken chain of comparisons, every link with a stated uncertainty. Your certificate records it.
✓
As-found / as-left readings
Before and after any adjustment, at every test point.
✓
Measurement uncertainty
Expanded uncertainty, k = 2, for each result.
✓
Reference standards used
With their own calibration status and traceability.
✓
Identification
Unique certificate number, instrument make, model and serial.
✓
Conditions
Temperature and humidity at the time of calibration.
TRACEABILITY CHAIN

ACCREDITATION SCOPE
For parameters marked Accredited, confirm coverage against the laboratory’s current accredited scope before booking. Traceable calibrations may fall outside that scope.

RELATED CASE STUDY
How an aerospace manufacturer cut calibration downtime without expanding its vendor list.
CHALLENGE
An illustrative test cell uses electrical meters, dimensional tools, pressure gauges and torque tools owned by different teams. The sample register lacks consistent identification and agreed measurement points.
RESULT
The illustrative deliverable is one reconciled equipment register with discipline-specific work scopes and a record-review checklist. This is a fictional planning example, not a documented customer result.
