DIN EN ISO 14405 series is part of the ISO GPS system, which is essential for anyone involved in the capture and communication of design information.
DIN EN ISO 14405 Part 1 establishes the default specification operator for linear size and defines a number of special specification operators for linear size for features of size, e.g. “cylinder”, “sphere”, “torus”, “circle”, “two parallel opposite planes”, or “two parallel opposite straight lines”.
The standard also defines the specification modifiers and the drawing indications for these linear sizes. Produced workpieces exhibit deviations from the ideal geometric form. The real value of the dimension of a feature of size is dependent on the form deviations and on the specific type of size applied. The type of size to be applied to a feature of size depends on the function of the workpiece. The type of size can be indicated on the drawing by a specification modifier for controlling the feature definition.
The German national foreword to the standard provides additional information on the procedure to be followed when re-using old drawings based on DIN 7167, and Annex F gives detailed information on the relation of this part of the series to other standards and the GPS matrix model.
The other standards making up the DIN EN ISO 14405 series on “Dimensional tolerancing” are Part 2: “Dimensions other than linear sizes” and Part 3: “Angular sizes”.
