Many French NF standards have direct equivalents in the ISO (International Organization for Standardization) or EN (European Standards) catalogs. If your company already subscribes to an international standards database (like IHS Markit or Techstreet), search for the equivalent ISO standard. It may already be included in your corporate subscription. 3. Manufacturer Data Sheets
If you are a student or researcher, check your institution's library database. Many technical universities provide students with free, legal access to AFNOR, ISO, and IEEE databases through institutional subscriptions.
For high-precision parts where every fraction of a millimetre counts.

While searching for a download is highly common, acquiring copyrighted standards through unauthorized channels poses security and compliance risks. Instead, utilize free manufacturer catalogs, equivalent ISO/DIN standards, or engineering library databases to get accurate, legal data for your mechanical designs.

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).
For professionals in sheet metal working, the NF E 02-352 provides the baseline for quality control. While machined parts often follow , cut and folded parts require these specific French standards to account for the unique stresses and material behaviors of bending and cutting.
Approved steel grades, stainless steel classes, or non-ferrous alloy specifications. For high-precision parts where every fraction of a
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
| Feature | Description | | :--- | :--- | | | Étroite (fine), normale (medium), large (coarse)—allow engineers to match precision requirements with manufacturing costs. | | Dimensional Tolerances | Cover external dimensions, internal dimensions (punched holes or cutouts), and center distances. | | Geometrical Tolerances | Include flatness, straightness, and angular deviations for cut or bent edges. | | Verification Methods | Describe how to measure the part and check compliance. | | Excluded Elements | Do not apply to burrs (covered by NF E 81-010), weld radii, or parts made by stamping or after heat treatment. |
