The NF E 02-352 standard is established by AFNOR (Association Française de Normalisation), the French national organization for standardization.
These classes are applied based on the thickness of the material (e.g., mm, etc.). NF E 02-352 PDF Free: How to Access the Standard nf e 02352 pdf free
The NF E02-352 standard is a technical specification for general tolerances. It is applied to dimensions that do not have individual tolerance indications on a technical drawing. General tolerances are the default acceptable deviations for a part’s features. Its main provisions include:
The French standard 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.

(officially titled "Geometrical product specifications (GPS) - General tolerances (dimensional and geometrical) for cutted and bended workpieces") is a French standard that outlines the general tolerances for dimensions and geometry on parts that have been cut (sheared, laser cut, punched) and bent.
The French standard dictates the dimensional and geometrical tolerances for cut and bent sheet metal workpieces that lack individual tolerance callouts. For mechanical designers, manufacturing engineers, and procurement specialists working within the European and French industrial frameworks, securing a copy of this standard is vital to ensure high-quality sheet metal stamping and folding.
NF E 02-352 aligns closely with international ISO standards (such as ISO 286). It outlines the system of letter and number designations used to describe tolerances:
