Calibration Statement
Calibration Statement
All EXFO optical products (Light Sources, Fiber-Optic Power Meters, etc)
require a calibration for which local calibration centers with STQC labs
(ERTL, ETDC) can be availed. EXFO’s manufacturing and service center
calibrations are based on the ISO/IEC 17025 Standard, which states that
calibration documents must not contain a recommended calibration
interval, unless this has been previously agreed upon with the customer.
Validity of specifications depends on operating conditions. For example,
the calibration validity period can be longer or shorter depending on the
intensity of use, environmental conditions and unit maintenance. Under
normal use, EXFO recommends calibrating these units every year.
In order to ensure appropriate calibration follow-up, EXFO applies a
special label on its instruments; this label complies with the ISO/IEC 17025
standard and indicates the previous and next calibration dates. However,
until the required empirical data has been collected, EXFO recommends
that the next calibration date of an instrument be established according to
the following equation:
Next calibration date = Date of first usage + recommended calibration
period (as specified in the instrument user guide)
For Transport Datacom products, (SDH Analyzer, Ethernet traffic
analyzers,etc) validity of specifications depends also on operating
conditions. The calibration validity period can be longer or shorter
depending on the intensity of use, environmental conditions and unit
maintenance. Under normal use, EXFO recommends calibrating these
units every two years.
