## Geometrical product specifications (GPS) - Dimensional tolerancing - Part 1: Linear sizes

inactive
 Organization: CEN Publication Date: 1 December 2010 Status: inactive Page Count: 46 ICS Code (Limits and fits): 17.040.10
##### scope:

This part of ISO 14405 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. This part of ISO 14405 covers the following linear sizes:

- local size;

- two-point size;

- spherical size;

- section size;

- portion size;

- global size;

- direct global linear size;l

- east-squares size;

- maximum inscribed size;

- minimum circumscribed size;

- indirect global linear size;

- calculated size;

- circumference diameter;

- area diameter;

- volume diameter;

- rank-order size;

- maximum size;

- minimum size;

- average size;

- median size;

- mid-range size;

- range size.

This part of ISO 14405 defines tolerances of linear sizes when there is:

- a + and/or − limit deviation (e.g. 0/−0,019) (see Figure 9);

- an upper limit of size (ULS) and/or lower limit of size (LLS) (e.g. 15,2 max., 12 min. or 30,2/30,181) (see Figure 11);

- an ISO tolerance class code in accordance with ISO 286-1 (e.g. 10 h6) (see Figure 10)

with or without modifiers (see Tables 1 and 2).

This part of ISO 14405 provides a set of tools to express several types of size characteristic. It does not present any information on the relationship between a function or a use and a size characteristic.
