Calibration Programmes

A Calibration Programme declares, for a class of instruments, how often they are calibrated, how often they are checked in between, and when the programme itself is reconsidered (ISO/IEC 17025 §6.4.7, §6.4.10). It carries the §6.4.7 obligation that the programme be "reviewed and adjusted as necessary".

When the interval gets longer

Lengthening a recalibration interval is not a simple change of number. ESYD KO1-KRITE §4.5 asks for two things together, and the system enforces both:

A new justification. The text that justified the shorter interval is not enough — you must write a fresh one.
More frequent intermediate checks. The internal check frequency must become strictly greater than it was.

If either is missing, the save is refused with a message saying which. Shortening an interval is always allowed without conditions: it is itself a corrective action.

The frequency order, from most to least frequent, is: Before Use, Per Shift, Daily, Per Batch, Weekly, Monthly, Quarterly, Semiannually, Annually.

If this is missing

The programme is the central rule: instruments that point at no programme inherit no interval,

so the interval has to be typed into each one by hand. Any that is forgotten ends up with no next

calibration date — and then the overdue check never locks that instrument out (see

Instruments).

With no justification for the interval, ESYD's ΚΟ1-ΚΡΙΤΕ §4 is not satisfied: the assessor

asks why twelve months and not six. "That is how we found it" is not an answer.

Extending an interval with no recorded justification is the finding that gets written up.

Notes

The programme supplies the default. A particular instrument's next calibration date is computed on the instrument's own page and may use its own interval.
The date filters are labelled Created From/To but filter on Next Review.
