What is ISO 13715 - Dimensioning of technical products about?
Technical drawings are the common language of those involved in technological work. ISO 13715 specifies rules for the indication and dimensioning of undefined edges in technical product and dimensions. The proportions and dimensions of the graphical symbols to be used are also specified in ISO 13715.
In cases where the geometrically defined shape of an edge (for example, 1 × 45°) is required, the general dimensioning principles given in ISO 129-1 apply.
Who is ISO 13715 - Dimensioning of technical products for?
ISO 13715 on dimensioning of technical products is useful for:
- Engineers
- Architects
- Designers
- Technologists
- Technicians
- Specialized workers
Why should you use ISO 13715 - Dimensioning of technical products?
In technical drawings, the ideal geometric shape is represented without any deviation and, in general, without consideration of the conditions of the edges. Nevertheless, for many purposes (the functioning of a part or out of safety considerations, for example) particular conditions of edges need to be indicated. Such conditions include those of external edges free from burr or those with a burr of limited size, and internal edges with a passing.
ISO 13715 provides a symbology for the indication of the desired edge.
ISO 13715 also guides you with information on:
- Technical terms and definitions
- Indications on drawings
- Proportions and dimensions of graphical symbols
- Examples of indication of undefined edges
The guidelines in ISO 13715 help you get a clear idea on indication and dimensioning for documenting a technical product.
