This standard applies specifically to metal parts produced by cutting and bending techniques. Key Aspects of the NF E 02-352 Standard
Technical standards are periodically reviewed and revised. An older, leaked version might contain obsolete metrics, leading to critical manufacturing errors.
: Sets limits for various parameters, including: Linear dimensions (length, width). Radii of curvature. Bending angles. Flatness and straightness of cut edges.
NF E 02-352 standard is a French technical specification governing the Geometrical Product Specifications (GPS)
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.

: Ensuring rotating shafts possess the correct clearance to maintain lubrication films without vibrating loose.
If you are a student, researcher, or faculty member at a French university or engineering school, you likely have free access to AFNOR's online database, (formerly SagaWeb).
The standard provides specific tables based on the nominal size and thickness of the material (up to 10 mm). Feature Type Class Narrow (e) Class Normal (n) Class Wide (l) ±1∘plus or minus 1 raised to the composed with power ±1.5∘plus or minus 1.5 raised to the composed with power ±2∘plus or minus 2 raised to the composed with power Bending Height (1-6mm) ±0.1plus or minus 0.1 ±0.2plus or minus 0.2 ±0.4plus or minus 0.4 How to Access NF E 02-352 PDF
is a technical standard established by AFNOR (Association Française de Normalisation), the French national organization for standardization. Standards prefixed with "NF" represent French national standards, many of which align closely with European (EN) and international (ISO) compliance frameworks. Scope and Application This standard applies specifically to metal parts produced
It ensures that even when a designer doesn't specify a tolerance for a specific measurement, the manufacturer follows a standardized level of precision (Fine, Medium, Coarse, or Very Coarse). 🔍 Search for "Free PDF" Legally, AFNOR standards are copyrighted materials
