The official text for NF E 02-352 is a copyrighted French technical standard published by AFNOR (Association Française de Normalisation). Because it is a protected industrial standard, full copies are generally not available for free legally; however, key technical data and summary information are accessible through manufacturers and standard distributors. What is NF E 02-352?
NF E 02-352 (part of the Geometrical Product Specifications or GPS) establishes general tolerances for cut and bent workpieces. It is used when specific tolerances for dimensions and features are not individually marked on a drawing.
Scope: Specifically covers parts made from flat steel products (hot or cold rolled) that have undergone at least one plastic deformation operation, such as bending or folding. Tolerance Classes: It defines three classes of precision: Narrow (e): High precision. Normal (n): Standard industry precision. Wide (l): Lower precision for non-critical parts. Key Technical Data (Tolerances)
Technical summaries from manufacturers like Groupe TMA and Scribd provide the following typical tolerance ranges (in mm) based on thickness and nominal size: Nominal Size (mm) Narrow (e) Normal (n) Over 1 to 3 Over 3 to 6 Over 6 to 10
Values are simplified examples; specific tolerances vary by thickness range as well. Where to Access the Document

Quick Reference:
The standard NF E 02-352 is a French technical norm published by AFNOR (Association Française de Normalisation). It specifies Geometrical Product Specifications (GPS) for cut and bent workpieces. Overview of NF E 02-352
Title: Geometrical Product Specifications (GPS) — Cut and bent workpieces — Dimensional and geometrical tolerances for dimensions and features without individual tolerances.
Scope: The standard, effective since September 5, 1998, establishes general tolerances for linear and angular dimensions, as well as geometric features like flatness and straightness, specifically for cut and bent metal components.
Application: It provides default tolerance values for manufacturing when individual tolerances are not specified, fitting into the broader GPS framework to ensure consistency, often categorized by precision classes. Finding a Free PDF

The standard NF E 02-352 is a French technical specification by AFNOR (Association Française de Normalisation) that defines the general dimensional and geometrical tolerances for cut and bent workpieces. Because standard machining tolerances (like ISO 2768) often don't apply well to sheet metal processes, this standard was created to fill that gap for parts without individual tolerance indications. Core Purpose of NF E 02-352
The primary goal of NF E 02-352 is to simplify engineering drawings. Instead of detailing every single tolerance for a cut or bent part, a designer can simply reference this standard to ensure "good workmanship" accuracy.
Scope: It applies to parts cut and bent from flat steel products (rolled hot or cold).
Tolerance Classes: The standard establishes three precision levels: Narrow (e): For high-precision applications.
Normal (n): The default standard for most industrial applications.
Large (l): For less critical components where wider variations are acceptable. Technical Details and Tables (Invoking related search term suggestions now
The standard provides specific allowable deviations based on nominal dimensions and material thickness. Key areas covered include:
Dimensional Deviations: Limits for linear and angular dimensions of flat cut parts.
Bent Workpieces: General tolerances for the height of a folded edge and the positioning of openings relative to a bend.
Geometric Tolerances: Guidelines for coaxiality and symmetry, which vary depending on the thickness range (e.g., from 0.1 mm to over 10 mm). Accessing the PDF

NF E 02-352 standard is a French technical specification governing the Geometrical Product Specifications (GPS)
for cut and bent workpieces. It defines general dimensional and geometrical tolerances for metal parts where individual tolerances are not specifically indicated on a drawing. Core Purpose and Scope Target Application:
Specifically designed for workpieces produced by mechanical cutting (shearing, punching) and bending of flat steel products (hot or cold rolled). Gap Coverage:
Standard tolerances for machined parts (like NF EN 22768) are often unsuitable for the realities of sheet metal fabrication. NF E 02-352 was established to provide realistic baseline quality levels for these specific processes. Exclusions:
Does not apply to thermal cutting (laser, water jet), deep-drawn (stamped) parts, or burr heights. UNM - Union de Normalisation de la Mécanique Tolerance Classification
The standard organizes tolerances into three distinct classes based on manufacturing precision: Afnor EDITIONS Narrow (e):
High precision, typically requiring specialized tooling or more careful processing. Normal (n):
Standard workshop quality reflective of common fabrication capabilities. Large (l):
Looser tolerances for less critical parts, reducing production costs. Key Technical Provisions Dimensional Tolerances: Covers linear and angular dimensions. Geometrical Tolerances: Specifies limits for straightness and flatness. Supplemental Recommendations:
Provides guidelines for inclination, coaxiality, and symmetry. Thickness Ranges:
Tolerance values vary according to the nominal thickness of the material (e.g., specific ranges for 0.1mm to 10mm+). Groupe TMA Evolution and Availability
