It is crucial for modern engineers to note that standardization is a fluid process. Many specific French standards (NF) have been progressively replaced or harmonized with International Standards (ISO) to facilitate global trade.

If you interpret a French drawing using ASME rules, you will reject good parts (by requiring perfect form that isn't required). If you interpret an American drawing using NF E 02-352, you will accept bad parts (allowing form errors that should be rejected). Never mix standards. nf e 02-352 pdf

The NF E 02-352 standard provided a codified set of rules allowing drafters to omit non-essential details or represent them symbolically, ensuring that the drawing remained a clear instruction manual for the machinist rather than a photorealistic artwork. It is crucial for modern engineers to note

NF E 02-352 is a French national standard (Norme Française) establishing general tolerances for linear and angular dimensions, as well as geometric features, on cut and bent sheet metal workpieces. It serves as a, alternative to traditional machining standards by defining, three, levels of precision (Narrow, Normal, Large) for manufacturing compliance.

For long components like shafts, rods, or beams, the standard permits the use of "break lines."
