What this term settles

The term looks ordinary until two teams use it differently. The entry removes that room by naming the thing, its inputs and its limits in one sentence.

Who it binds

Nothing here creates an obligation by itself. The obligation arrives when the firm writes data sampling into a control, a specification or a purchase order.

What to do in your practice

Take the firm own definition of data sampling, put it beside this one and mark the differences. Each difference is either a deliberate local choice or an inconsistency to fix.

Evidence an auditor or regulator asks for

  • A controlled vocabulary entry for data sampling with the citation 3.2.4, an owner and a review date.
    An auditor can check that the term is controlled rather than assumed.
  • A data inventory field that records the entry for each dataset used in training or operation.
    Shows data sampling in use in the artefact the firm relies on, not only in a glossary.
  • A data quality record with the check, the date and the person who signed it off.
    The data inventory is organised by system rather than by dataset, so the same data is described twice with different labels.
Ask your teamIf two teams were asked what data sampling means, would their answers match this entry?

Common gaps this page catches

  • data sampling is used in the data record behind every AI system without a written definition, so two teams can mean different things.
  • A supplier uses the same word with a different boundary and nobody has recorded the difference.

What to prepare before the amendment lands

Brief the owners who use data sampling most often, then ask each to return one artefact that shows the entry in use. File the artefacts against the register row.

How to test it here

Take one live artefact rather than a template, find the sentence or field where data sampling is used, and put this page beside it. Record the answer, the artefact and the date, because that record is the evidence and a glossary entry on its own is only an intention.

What this page does not claim

The page does not reproduce the standard, certify the firm or predict the wording the amendment will use; it states data sampling at the claim level "definition" and stops where the public record stops.

Common questions

What does data sampling mean in ISO 22989?
choosing a subset of samples so that the patterns and trends of the larger dataset still show
What evidence should we keep for 3.2.4?
A controlled vocabulary entry for data sampling with the citation 3.2.4, an owner and a review date. A data inventory field that records the entry for each dataset used in training or operation.
Is data sampling a requirement?
No: data sampling is a definition or clause of a terminology standard, and it becomes binding only when a firm writes it into a policy, a contract or a procedure, or when another standard incorporates it.
