ISO DIS 14405-2

Description / Abstract: This part of ISO 14405 defines the use of geometrical tolerances for dimensions that are not linear sizes to avoid the ambiguity that the use of ± tolerances on this type of dimensions causes. Both linear and angular dimensions, except size, are covered by this document.

Dimensional tolerancing can be indicated by ± tolerancing or geometrical tolerancing.

The ambiguity caused by using ± tolerances for dimensions other than linear sizes (for individual tolerances and general tolerances according to, e.g. ISO 2768-1 and ISO 8062-3) is explained in Annex A. For indications of size tolerances, see:

— ISO 14405-1 for linear size;

— ISO 2538 for wedges;

— ISO 3040 for cones.

The figures, as shown in this part of ISO 14405, merely illustrate the text and are not intended to reflect actual usage. The figures are consequently simplified to indicate only the relevant principles.
