ISO 2768: AS9102 glossary definition

What ISO 2768 means

ISO 2768 is a general tolerance standard often referenced on drawings to define default tolerances for dimensions that do not carry an explicit tolerance.

When a drawing invokes ISO 2768, the FAIR reviewer has to know which class and section apply before deciding the requirement for an untoleranced dimension.

Use this term as a review cue: it should help connect a drawing requirement, specification, certificate, result, or approval field to the evidence a customer will inspect. If the purchase order or customer portal uses stricter wording, follow that controlled source instead of this glossary entry.

Where it appears in AS9102

ISO 2768 can affect Form 3 requirement entries because the tolerance may come from the drawing note or title block rather than being printed next to the dimension.

In an Articul review, this term is treated as part of the traceability path from source drawing or flowed requirement to form field, evidence, validation issue, and final approval. Use the AS9102 standard text as the controlled source, and use this glossary to clarify reviewer-facing meaning before export. When the term is ambiguous, keep the reviewer note close to the row or field it affects.

Review notes

• Capture the applicable class or drawing note context in the requirement so the result can be evaluated without making the reviewer reconstruct the tolerance separately.
• Do not leave an untoleranced dimension as nominal only when the drawing invokes a general tolerance standard that defines the acceptance range.
• Keep wording, units, identifiers, and attachment names consistent across the drawing, Forms 1-3, evidence files, and any customer portal submission.
