Rubber or plastics hoses and tubing - Bending tests (ISO 1746:1998, including technical corrigendum 1:1999)

Gummi- oder Kunststoffschläuche mit und ohne Einlage - Biegeprüfungen (ISO 1746:1998, einschließlich technischen Corrigendum 1:1999)

Diese Internationale Norm legt zwei Verfahren fest zur Bestimmung des Verhaltensvon Gummi- oder Kunststoffschläuchen mit oder ohne Einlage unter Biegung bei einem festgelegten Radius. Verfahren A ist geeignet für Schläuche mit und ohne Einlage mit Innendurchmessern bis 80 mm. Die Abmessungen der Prüfeinrichtung zur Prüfung von Schläuchen mit und ohne Einlage größerer Innendurchmesser würden zu ausladend.

Tuyaux et tubes en caoutchouc ou en plastique - Essai de courbure (ISO 1746:1998, corrigendum technique 1:1999 compris)

La présente Norme internationale spécifie deux méthodes de détermination du comportement des tuyaux et tubes en caoutchouc ou en plastique lorsqu'ils sont courbés selon un rayon donné. La méthode A convient pour des tuyaux et tubes de diamètre intérieur inférieur ou égal à environ 80 mm; la taille de l'appareillage d'essai pour les tuyaux et tubes de dimensions supérieures devient excessive. Cette méthode permet également de mesurer la force requise pour obtenir un rayon de courbure donné, et l'essai peut être effectué à une pression interne donnée. Avec la méthode B, les caractéristiques de courbure, y compris la force requise pour obtenir la courbure, peuvent être déterminées dans une plage de températures allant de - 60 °C à + 200 °C. Cependant, du fait de sa nature, l'appareillage ne peut être utilisé que pour des tuyaux et tubes de faible diamètre intérieur, jusqu'à environ 12,5 mm.

Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national standards bodies (ISO member bodies). The work of
preparing International Standards is normally carried out through ISO
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. ISO
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 ISO 1746 was prepared by Technical Committee
ISO/TC 45, Rubber and rubber products, Subcommittee SC 1, Hoses
(rubber and plastics).
This third edition cancels and replaces the second edition (ISO 1746:1983),
which has been technically revised.

INTERNATIONAL STANDARD  ISO ISO 1746:1998(E)
Rubber or plastics hoses and tubing — Bending tests
WARNING — Persons using this International Standard should be familiar with normal laboratory practice.
This standard does not purport to address all of the safety problems, if any, associated with its use. It is the
responsibility of the user to establish appropriate safety and health practices and to ensure compliance
with any national regulatory conditions.
1  Scope
This International Standard specifies two methods for the determination of the behaviour of rubber or plastics hoses
or tubing when bent to a specified radius.
Method A is suitable for hoses and tubing of internal diameter up to about 80 mm; the size of the apparatus for
testing hoses and tubing of larger bore sizes becomes excessive. The method also provides a means of measuring
the force required to reach a specified bend radius, and the test may be carried out at a specified internal pressure.
In method B, the bending characteristics, including the force required for bending, may be determined over a range
of temperatures from - 60 �C to + 200 �C. The nature of the apparatus, however, limits its applicability to hoses and
tubing of small internal diameter, i.e. up to about 12,5 mm.
