GD&T Free Resource: ISO Geometrical Tolerancing Glossary of Symbols and Terms ISO Geometrical Tolerancing Glossary As the globalization of manufacturing continues, the ISO standards will play a more significant role in the U.S. If your company is interested in global sourcing and learning how to read drawings created in other countries, ETI's ISO Geometrical Tolerancing workshop is vital to your success. Learn the ins and outs of utilizing the ISO standards and gain a fundamental knowledge of ISO 1101:2004, related standards, and their application on drawings. The course includes, a unique reference guide that will help you to learn about dimensioning and tolerancing and provide a handy reference for you on the job. The terms listed below are from the glossary section of the reference guide.
The following terms are related to ISO geometrical tolerancing. The definitions are from ISO 1101:2004 and its companion published standards.
ISO Tolerances for Holes (ISO 286-2) ISO Tolerances for Holes (ISO 286-2) Nominal hole sizes (mm) over 3.
• that teaches the changes to the standard • Order an • Order the Actual Size — The size of a feature, obtained by measurement (ISO 286-1:1998) Actual Local Size — Any individual distance at any cross section of a feature, i.e. Based on ISO 1101:2004 and companion standards Alex and his team of dimensional engineering mentors spent nearly a year compiling information about the ISO GPS standards. Alex Krulikowski's ISO Geometrical Tolerancing Reference Guide allows the reader to quickly and easily look up information on a topic without having to navigate through numerous ISO standards. Carry it with you on the job and have a resource to all your ISO geometrical tolerancing questions at your fingertips. Click the graphic to look inside the book. Extreme Boundary — A general term referring to a theoretical worst-case boundary. An extreme boundary may be an envelope boundary, a virtual condition, or a calculated boundary.
Feature of Size — A geometrical shape defined by a linear or angular dimension that is a size. Typically, a feature of size is a cylinder, a sphere, two opposite parallel surfaces, a cone or wedge.

Least Material Size (LMS) — A dimension defining the least material condition of a feature (ISO 2692:2006) Least Material Virtual Condition (LMVC) — state of associated feature of least material virtual size (LMVS). For features in the inspection domain, LMVC identifies a condition equivalent to LMVS.
Perpendicularity Tolerance — A geometrical tolerance that defines the allowable deviation from a right angle Position Tolerance — Defines the allowable deviation from the theoretically exact dimensions. A position tolerance can also be used to define permissible deviation for orientation and form. Profile Any Line — A geometrical tolerance that defines a requirement for the permissible location, orientation and form deviation of a line element of a profile defined with a TED. A profile any line tolerance is used on line elements that are not nominally straight. A profile any line tolerance frame should be applied to the integral feature or its extension line with a directed leader (ISO 1101:2004) Profile Any Surface — A geometrical tolerance that defines a requirement for the permissible size, location, orientation and form deviation of a workpiece profile defined with a TED.
