Full title and description

ISO 10579:2010 — Geometrical product specifications (GPS) — Dimensioning and tolerancing — Non-rigid parts. This International Standard gives rules for dimensioning and tolerancing non-rigid parts where restraining of features is required during verification of dimensions and tolerances specified on a drawing.

Abstract

ISO 10579:2010 specifies the conventions and indications to be used on technical drawings for flexible or non‑rigid components so that dimensions and tolerances can be verified under defined restraint/fixturing conditions. It clarifies how features of non‑rigid parts should be located, restrained and measured to obtain repeatable inspection results.

General information

• Publication date: 26 February 2010 (edition 2 published in early 2010).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 01.100.20 (Mechanical engineering drawings / GPS).
• Edition / version: Edition 2 (2010).
• Number of pages: 6.

Scope

Applies to the dimensioning and tolerancing of parts that are not rigid in normal handling and which therefore require specified restraining or fixturing when being measured. The standard provides rules for indicating on drawings how such parts are to be supported or clamped during verification so that specified dimensions and tolerances are meaningful and reproducible.

Key topics and requirements

• Definition and treatment of "non‑rigid" features for drawing and inspection purposes.
• Requirements for indicating fixturing/restraint methods on drawings to ensure consistent measurement conditions.
• Guidance on datum reference selection and interpretation when parts deform under restraint.
• Interaction with general GPS rules (application of geometric tolerancing symbols and frames to flexible components).
• Notes on verification practice to achieve repeatable dimensional inspection of non‑rigid parts.

Typical use and users

Used by mechanical designers, drafting engineers, manufacturing engineers, quality/metrology personnel and technical illustrators who specify, produce or inspect flexible components (e.g., thin metal sheet parts, rubber/elastic components, thin plastics, and other assemblies where parts deform under handling or clamping). It is also used by standards committees and tooling/fixture designers to define measurement procedures for non‑rigid items.

Related standards

ISO 10579:2010 is part of the GPS (Geometrical Product Specifications) family and is intended to be used alongside foundational GPS standards such as ISO 1101 (geometrical tolerancing), ISO 129 (dimensioning practices), ISO 8015 (fundamental tolerancing principle) and other GPS datum/positional standards. National and regional identical/adopted versions (EN ISO 10579, etc.) also exist.

FAQ

Q: What is this standard?

A: ISO 10579:2010 is an ISO standard in the Geometrical Product Specifications (GPS) series that gives rules for dimensioning and tolerancing parts that are non‑rigid and require restraint during measurement.

Q: What does it cover?

A: It covers how to indicate restraint/fixturing on drawings, how to select and interpret datums and dimensions for parts that deform, and how to make tolerances and measurements reproducible for non‑rigid items.

Q: Who typically uses it?

A: Mechanical designers, CAD/drafting teams, manufacturing and tooling engineers, quality assurance and metrology staff, and standards committees working on drawing and inspection practices for flexible components.

Q: Is it current or superseded?

A: ISO 10579:2010 (Edition 2) is published and was reviewed/confirmed in 2020; a technical corrigendum (ISO 10579:2010/Cor 1:2011) exists to correct the edition where applicable. The standard is listed for future review and work to revise or replace it has been recorded in ISO work items.

Q: Is it part of a series?

A: Yes — it belongs to the GPS family of standards (Geometrical Product Specifications and verification) and is intended to be used together with other GPS standards such as ISO 1101 and related drawing/tolerancing documents.

Q: What are the key keywords?

A: Non‑rigid parts, flexible parts, GPS, dimensioning, tolerancing, restraint, fixturing, datum, inspection, technical drawings, ISO 10579.
