NF EN ISO 3098-0
Technical product documentation. Lettering. Part 0 : general requirements.
La présente norme définit les caractéristiques des caractères courants à utiliser pour l'écriture sur les dessins techniques originaux et documents associés. Elle concerne les textes écrits à l'aide de trace-lettres, de caractères transfert ou de machines à écrire propres aux bureaux d'études. Les autres méthodes d'écriture doivent s'en approcher au mieux. Elle s'applique à tous les domaines techniques (mécanique, électricité, génie civil, architecture, etc.) en vue de faciliter les échanges de dessins et d'assurer la cohérence entre eux. Cela n'exclut pas que, dans certains domaines spécifiques, des indications complémentaires ou plus détaillées soient prescrites dans des normes particulières.
ISO 3098-1:2015 specifies the general requirements for lettering, in accordance with the other parts of ISO 3098, to be used in technical product documentation (in particular on technical drawings). It includes basic conventions as well as rules for the application of lettering using the following techniques: free-hand lettering (by means of an underlaid "grid"); templates and manual lettering instruments; dry transfer systems; numerically controlled lettering and draughting systems.
The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
