However, I worked at the design office of a company that was an AFNOR branch, but we didn't have the standards at the design office. We asked for them according to what we designed (if necessary)
What standards do you have available in your design office?
Do you think you have them all?
There are so many that you can't own everything, then you make your choice according to your activity.
In all the audits I have undergone, I have been told about the very specific standards that relate to the profession, but never about a general standard on the design office.
Just look at the question I asked about the symbol, no one has posted an excerpt of the standard, on the other hand many people say that they use it...
The standards were mainly founded by large companies in the automotive or aeronautical industries. They are developed by experts from different companies. The GDI is the cartoonist's bible and includes some excerpts from the standard. For this one, it actually corresponds to everything that is of the order of technical drawing, something you learned in school. The purpose of standards is to speak the same language between customers and supplier. Now nothing prevents you from derogating from it if you don't refer to it and if you write in your plan everything that will allow you to make your part (dimension, tolerance, surface finish, material, etc.) The more rigorous you want to be, the more we refer to standards because today companies are standardizing more and more and each company can create its own standards such as that of its company logo by including all the dimensional and usage specificities.
Standards exist at VW Renault, PAS, Toyota, Bosch etc... and these are available to suppliers on their web portal.
What is not normal is that of the organizations that make them pay.
