Geometrical product specifications (GPS) — Dimensional tolerancing — Part 1: Linear sizes
ISO 14405-1:2010 establishes the default specification operator for linear size and defines a number of special specification operators for linear size for feature of size types “cylinder” and “two parallel opposite planes”. It also defines the specification modifiers and the drawing indications for these linear sizes. It covers the following linear sizes: local size; global size; calculated size; and rank-order size.
ISO 14405-1:2010 defines tolerances of linear sizes when there is a + and/or – limit deviation, or when there is an upper limit of size and/or lower limit of size; with an ISO size tolerance code in accordance with ISO 286-1, with or without modifiers.
ISO 14405-1:2010 provides a set of tools to express several types of size characteristics. It does not present any information on the relationship between a function or a use and a size characteristic.
