BS EN ISO 128‑1:2020 pdf download.Technical product documentation (TPD) – General principles of representation.
4 Arrangement of the ISO 128 series The ISO 128 series specifies the graphical representation of objects in technical drawings with the aim of facilitating the international exchange of information on drawings and ensuring their uniformity in a comprehensive system. — ISO 128‑1 for fundamental requirements; — ISO 128‑2 for line types; — ISO 128‑3 for views, cuts and sections; — ISO 128‑15 for representation of shipbuilding technical drawings; — ISO/TS 128-71 for simplified representation of mechanical engineering technical drawings; — ISO 128‑100 for index of subject topics. Within these subject groupings, parts consist of requirements and applications for the different industrial branches – a concept allowing the integration of future developments. A matrix of the structure of the ISO 128 series (excluding this document) is given in Table 1. Only those parts which are publicly available at the time of publication of this document are indicated.
