ISO 14253-1:2017 Geometrical product specifications (GPS) — Inspection by measurement of workpieces and measuring equipmentPart 1: ISO - International Organization for Standardization INTERNATIONAL STANDARD ISO 14253 1.pdf

ISO 14253-1 establishes decision rules for verifying product conformity in Geometrical Product Specifications (GPS), utilizing guard bands based on measurement uncertainty to resolve disputes between suppliers and customers. It defines three zones—acceptance, rejection, and uncertainty—to ensure that to prove conformity, the measured value must remain within specifications after accounting for uncertainty, with a default 95% confidence level.
