The standard, titled "Geometrical product specifications (GPS) — Inspection by measurement of workpieces and measuring equipment — Part 1: Decision rules for verifying conformity or nonconformity with specifications," provides a technical framework for making quality decisions when measurement results are near specification limits. Core Principles of ISO 14253-1
When verifying nonconformity, the uncertainty zone is part of the acceptance zone (3.8) and not part of the rejection zone (3.10). iTeh Standards international standard iso 14253 1pdf exclusive
Before diving into the PDF exclusivity, we must cover the basics. ISO 14253-1 is titled "Geometrical product specifications (GPS) — Inspection by measurement of workpieces and measuring equipment — Part 1: Decision rules for verifying conformance or nonconformance with specifications." ISO 14253-1:2017 The standard
Ensures that accepted parts definitely meet specifications, reducing the risk of functional failures. international standard iso 14253 1pdf exclusive
If the measurement falls within the uncertainty range of the limit, neither conformity nor nonconformity can be proven under the default rules. Visualizing the Acceptance Zone The following graph demonstrates how the Acceptance Zone is narrower than the Specification Zone due to the "Guard Band" (measurement uncertainty Industry Significance Legal Protection:
