Recommended steel grades, hardness levels, and surface finishes.
The NF E 02-352 standard falls under the umbrella of . It is specifically designed to handle the unique physical realities of manufacturing parts made from hot-rolled or cold-rolled flat steel products via plastic deformation (such as laser cutting, stamping, and press brake bending).
Specifies the exact width, depth, and radii of the recesses machined into shafts or bores.

Understanding NF E 02-352: General Tolerances for Cut and Bent Workpieces
Clear tolerance zones prevent machinists from over-processing parts or producing components that fail quality control.
The underlying reason for this is . The revenue from selling standards funds the entire standardization process, including the salaries of experts, the cost of research, and the maintenance of official databases. Without this, the system would collapse. Remember that in professional and legal contexts, you are required to work from the official, up-to-date version of a standard. Using an unauthorized copy exposes you and your organization to significant legal and compliance risks. Specifies the exact width, depth, and radii of
: General positioning tolerances for interior holes, slots, or cutouts relative to a bent baseline. NF E 02-352 vs. ISO 2768: What is the Difference?
: Laminated steel sheets (both hot-rolled and cold-rolled). The Three Tolerance Classes of NF E 02-352
When sheet metal is sheared, punched, or bent, the material behaves elastically and plastically. Factors like springback, grain direction, and tool wear make it incredibly difficult to hit absolute dimensions. Rather than cluttering a technical drawing with thousands of individual tolerances, specifying "General Tolerances according to NF E 02-352" covers all undefined features. Scope and Core Applications The underlying reason for this is
is an essential tool for anyone drafting or reading French technical piping drawings. It harmonizes the visual language of engineering, reducing errors in fabrication and installation.
The standard is designed to streamline the engineering process. Instead of specifying tolerances for every single dimension, designers can refer to NF E 02-352 in their technical drawings. 1. Tolerances for Cut Pieces
