Introduction

This page deals with design of mechanical pieces, regarding applicable standards or requirements.

General requirements

General standards to be applied when designing a standard use mechanical part

In each mechanical drawing, the following general standards have to be indicated in order to guarantee the drawing tolerances for a general component

ISO-2768-mK - General tolerances (mk = medium level)
ISO-1302 - Geometrical Product Specifications (GPS)
ISO-13715 - Technical product documentation - Edges of undefined shape

Roughness requirements for electrical and thermal contact surfaces

The roughness have to be indicated in each mechanical drawing, pointing the surface to be treated. A standard value for a good electrical and thermal contact is < 3.2 µm

Edges of undefined shape for general parts

The edges of undefined shape values have to be indicated in each mechanical drawing.
Standard values for general pourpose mechanical parts according to the ISO-13715 are:

Outer edges: –0.3 mm / –0.5 mm
Inner edges: +0.5 mm / +0.3 mm
