Pipework components - Definition and selection of DN (nominal size) (ISO 6708:1995)

Cancels and replaces the first edition (1980). Gives the definition of DN (nominal size) when applied to components of a pipework system, as specified in those standards which use the DN designation system. Gives a list of preferred DN values.

Rohrleitungsteile - Definition und Auswahl von DN (Nennweite) (ISO 6708:1995)

Diese Norm legt die Definition von DN (Nennweite) bei Bauteilen von Rohrleitungen fest, die in Normen, die das DN-System verwenden, festgelegt sind. Anmerkung 1: Andere Bezeichnungsweisen sind auch gebräuchlich, z.B. Erzeugnisse mit Gewinde oder Schneidringverbindungen, gelöteten oder geschweißten Verbindungen oder Erzeugnisse die mit NPS, OD (Außendurchmesser) oder ID (Innendurchmesser) bezeichnet sind, diese sind jedoch nicht in dieser Norm definiert.

Composants de réseau de tuyauteries - Définition et sélection des DN (diamètre nominal) (ISO 6708:1995)

La présente Norme internationale donne la définition de DN (diamètre nominal) lorsqu'elle est appliquée à des composants d'un réseau de tuyauteries, comme spécifié dans celles des normes qui utilisent le système de désignation par DN.  
NOTE 1 D'autres méthodes de désignation de dimension sont aussi utilisées, par exemple produits ayant des extrémités à raccordements filetés, à compression, brasés ou soudés, ou produits désignés par NPS (dimension nominale du tube), DE (diamètre extérieur), DI (diamètre intérieur), mais celles-ci ne sont pas définies dans la présente Norme internationale. La présente Norme internationale donne une liste des valeurs de DN préférentielles.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been established 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. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 6708 was prepared by Technical Committee
lSO/TC 5, Ferrous metal pipes and metallic fittings, Subcommittee SC 10,
Metallic flanges and their joints.
