About This Item
TS 88-50 ISO 128-50 sets out the basic conventions for representing cut areas in technical drawings, using the orthographic projection methods defined in ISO 5456-2 as its visual framework. It is relevant across drawing disciplines such as mechanical, electrical, architectural, and civil engineering, where sectional views need to be presented in a clear and consistent way.
Why section representation matters
Sections are used to reveal internal form that would otherwise be hidden in an external view. This standard addresses the general principles for showing the cut surface itself, so that hatching, boundary perception, and the relationship between the sectioned area and the rest of the drawing are interpreted consistently. In practice, that consistency helps different technical teams read drawings in the same way, even when they work in different industries.
Position within the ISO 128 family
The ISO 128 series covers presentation rules for technical drawings from several angles. This part focuses specifically on the representation of areas on cuts and sections, while aligning with orthographic projection practice from ISO 5456-2. Together with related terminology, linework, and presentation standards, it supports a uniform technical drawing language for engineering documentation.
