Technical product documentation (TPD) - General principles of representation - Part 3: Views, sections and cuts (ISO 128-3:2022)
This document specifies the general principles for presenting views, sections and cuts applicable to various kinds of technical drawings (e.g. mechanical, electrical, architectural, civil engineering), following the orthographic projection methods specified in ISO 5456-2. Views and sections for shipbuilding technical drawings are discussed in ISO 128-15. Views and sections for 3D models are discussed in ISO 16792.
Attention has also been given in this document to the requirements of reproduction, including microcopying in accordance with ISO 6428.
Technische Produktdokumentation (TPD) - Allgemeine Grundlagen der Darstellung - Teil 3: Ansichten, Schnitte und Schnittansichten (ISO 128-3:2022)
Dieses Dokument legt die allgemeinen Grundlagen zur Darstellung von Ansichten, Schnitten und Schnittansich
ten fest, die für verschiedene Arten von technischen Zeichnungen anzuwenden sind (z.B. Mechanik, Elektrik, Architektur, Tiefbau), wobei die in ISO5456-2 festgelegten orthogonalen Projektionsmethoden befolgt werden. Ansichten und Schnitte in technischen Zeichnungen des Schiffbaus sind Gegenstand von ISO128-15. Ansichten und Schnitte in 3D-Modellen sind Gegenstand von ISO16792.
Die Anforderungen an die Vervielfältigung, einschließlich Mikroverfilmung nach ISO6428, wurden in diesem Dokument ebenfalls berücksichtigt.
Documentation technique de produits (TPD) - Principes généraux de représentation - Partie 3: Vues, sections et coupes (ISO 128-3:2022)
Le présent document établit les principes généraux de représentation des vues, des sections et des coupes applicables aux différents types de dessins techniques (par exemple génie mécanique, génie électrique, génie architectural, génie civil) suivant les méthodes de projection orthographique, spécifiées dans l'ISO 5456-2. Les vues et sections pour les dessins techniques de construction navale sont discutées dans l’ISO 128-15. Les vues et sections pour les modèles 3D sont discutées dans l’ISO 16792.
Les spécifications du présent document ont été établies en tenant compte des exigences de reproduction, y compris celles de la micrographie, conformément à l'ISO 6428.
Tehnična dokumentacija izdelkov - Splošna načela prikazovanja - 3. del: Pogledi, prerezi in odrezi (ISO 128-3:2022)
Ta dokument določa splošna načela za predstavitev pogledov, prerezov in odrezov, ki se uporabljajo za različne tehnične risbe (npr. v strojništvu, elektrotehniki, arhitekturi, gradbeništvu) v skladu z metodami ortografske projekcije, določenimi v standardu ISO 5456-2. Pogledi in prerezi za tehnične risbe v ladjedelništvu so obravnavani v standardu ISO 128-15. Pogledi in prerezi za 3D-modele so obravnavani v standardu ISO 16792. Dokument obravnava tudi zahteve za reproduciranje, vključno z mikrokopiranjem v skladu s standardom ISO 6428.
