Technical drawings - Simplified representation of centre holes (ISO 6411:1982)
This representation mode may be used particulary when it is not necessary to show the exact form and size and where the designation of standardized centre holes is sufficient for information. Annex A gives the dimensions for types R, A and B, and Annex B the proportions and dimensions of symbols.
Technische Zeichnungen - Vereinfachte Darstellung von Zentrierbohrungen (ISO 6411:1982)
Diese Norm legt die vereinfachte Darstellung von Zentrierbohrungen und deren Bezeichnung fest. Die vereinfachte Darstellung von Zentrierbohrungen kann besonders dann angewendet werden, wenn es nicht notwendig ist, die genaue Form und Größe darzustellen und die Bezeichnung von genormten Zentrierbohrungen als Information genügt.
Dessins techniques - Représentation simplifiée des trous de centre (ISO 6411:1982)
La présente Norme internationale spécifie une représentation simplifiée des trous de centre et leur désignation. La représentation simplifiée des trous de centre peut être utilisée en particulier lorsqu'il n'est pas nécessaire de montrer la forme et les dimensions exactes des trous de centre et que leur désignation normalisée suffit pour l'information.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards institutes (ISO memher bedies). The work of developing lnter-
national Standards is carried out through ISO technical committees. Every member
hody interested in a subject for which a technical committee has been set up has the
right to be represented on that committee. 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 to
the member bodies for approval before their acceptance as International Standards by
the ISO Council.
International Standard ISO 6411 was developed hy Technical Committee ISO/TC 10,
Technical drawings, and was circulated to the member bedies in January 1980.
