Technical drawings - Requirements for microcopying (ISO 6428:1982)

The rules of ISO 128, ISO 3098, ISO 5457 are expanded. The requirements will provide for high quality microforms with which legible enlargement copies can be made, and documents complying with them can also be reproduced by any other reprographic system. It is recommended that all drawing office documents be executed in accordance with this International Standard.

Technische Zeichnungen - Anforderungen für die Mikroverfilmung (ISO 6428:1982)

Die vorliegende internationale Norm legt die Anforderungen fest, die bei der Ausführung von technischen Zeichnungen und anderen von Konstruktionsbüros erstellten Originaldokumenten, welche mikroverfilmt werden sollen, zu beachten sind. Die Einhaltung dieser Anforderungen ergibt Mikrofilme hoher Qualität, von denen gut Rückvergrößerungen hergestellt werden können. Die Anwendung dieser Regeln wirkt sich auch bei anderen Reproduktionsmethoden günstig aus.

ISO (the International Organization for Standardization} is a worldwide federation of

national Standards bodies (ISO member bedies). The wsrk of developing International

Standards is carried out through ISO technical committees. Every member body

interested in a subject for which a technical committee has been authorized has the

right to be represented on that csmmittee. International organizations, governmental

and non-governmental, in liaison with ISO, also take part in the work.

Draft International Standards adopted by the technical committees are circulated ts

the member bodies for approval before their acceptance as International Standards by

the ISO Council.
