The component that supports the compressor and connects it to the engine is our focus we’ll call it the “compressor base”. Figure 1 shows a vehicle engine with a compressor for AC. In order to understand the content of this standard and its parts, it’s best to use a real engineering example. Such instances are normal, and not uncommon, so you should always check the drawing title block for general tolerance requirements and note any special part specifications or project requirements.
WHAT IS ISO 2768 MK ISO
The standard is made of general rules because there are exceptions when a dimension on a part needs a tighter tolerance than those set by ISO 2768. By including the ISO 2768 specification, you are simplifying your drawing, and avoiding writing tolerances for every dimension and feature.
