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): nf e 02352 pdf free
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

The French standard NF E 02-352 is a technical document that establishes the general dimensional and geometric tolerances for cut and bent metal parts. It is primarily used in mechanical engineering and manufacturing to define acceptable variations in parts made from sheet metal through processes like stamping, punching, or folding. Key Content Overview
The document is structured to provide a framework for quality control when specific individual tolerances are not indicated on a drawing.
Scope: Applies to cut and bent parts made from hot-rolled or cold-rolled flat steel products. Tolerance Classes: It defines three levels of precision: Narrow (E): For high-precision requirements. Normal (N): The standard industry default. Large (L): For less critical components.
Geometric Characteristics: Sets limits for various parameters, including: Linear dimensions (length, width). Radii of curvature. Bending angles. Flatness and straightness of cut edges.
Verification Methods: Includes simplified methods for checking these characteristics during production. Accessing the Document
Since NF standards are copyrighted technical documents, they are typically sold through official bodies like AFNOR (the French Association for Standardization). However, you can find information or previews through the following channels:
Reference Summary: A partial preview and summary of the document's scope can be viewed on Scribd.
Commercial Standards: Detailed technical data on tolerances for oxyfuel and sheet metal cutting is often summarized in manufacturer guides, such as the TMA Standard Tolerances Guide, which references these norms.

📏 The "Invisible Hand" of Manufacturing: Understanding NF E 02-352
Ever wonder why two pieces of metal, cut in different factories, can still be bolted together without a gap? It isn’t magic—it’s NF E 02-352.
In the world of manufacturing, perfection is impossible. Every time a machine cuts or bends a piece of steel, there is a tiny margin of error. This standard provides the "General Tolerances" that tell engineers exactly how much "imperfection" is allowed before a part is considered a failure. 🛠️ What’s Inside the Document?
The standard specifically targets cut and bent workpieces. It provides tables that define three main "Tolerance Classes":
f (fine): For high-precision parts where every fraction of a millimetre counts. If you are working in French industrial engineering,
m (medium): The industry standard for general mechanical engineering.
c (coarse): Used for rugged parts where a bit of "wiggle room" won't hurt the final product. 🔍 Why You Should Care (Even if You Aren't an Engineer)
Safety: Without these standards, the "bent" parts in a plane's wing or a car's chassis might not handle stress correctly.
Cost: Specifying a "fine" tolerance when a "coarse" one will do can double the price of a part. Engineers use NF E 02-352 to find the "sweet spot" between quality and cost.
Global Language: It allows a designer in Paris to send a blueprint to a factory in Tokyo and get exactly what they expected. 📂 Finding the PDF
While some older versions of standards are archived, official documents like NF E 02-352:2013 are typically managed by Afnor EDITIONS. You can find detailed summaries and purchase the full 29-page guide through the Afnor Boutique or technical libraries like Intertek Inform.

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
