Rubber and plastics hoses and tubing - Measurement of flexibility and stiffness - Part 1: Bending tests at ambient temperature (ISO 10619-1:2017)

This document specifies three methods for measuring the flexibility of rubber and plastics hoses and
tubing (methods A1, B and C1), where the deformation of the hose or tubing is measured, and two
methods for measuring the stiffness (methods A2 and C2) by measuring the force required to bend
rubber or plastics hoses or tubing to a specific radius at ambient temperature.
Methods A1 and A2 are suitable for rubber and plastics hoses and tubing with inside diameter of up to
and including 80 mm.
Method A1 allows the measurement of the flexibility of the hose or tubing by measuring the reduction
in outside diameter when the hose is compressed between two plates.
Method A2 provides a means of measuring the force required to reach a specific bend radius when the
hose or tubing is compressed, as between two plates. The test can be carried out at a specified internal
pressure.
Method B is suitable for rubber and plastics hoses and tubing with inside diameter of up to and
including 100 mm, and provides a means of assessing the behaviour of the hose and tubing when bent
around a mandrel. The final mandrel diameter used can be taken as the minimum bend radius of the
hose or tubing. As this value is determined by the reduction of the outside diameter, it can be used as a
measure of the flexibility of the hose or tubing. The hose or tubing being tested can be unpressurized,
pressurized or under vacuum and, if required, with the curvature or against the curvature of the hose
or tubing, if such curvature is present.
Methods C1 and C2 are suitable for rubber and plastics hoses and tubing with inside diameter of
100 mm and greater.
Method C1 provides a means of determining the flexibility of the hose and tubing at the minimum
bend radius.
Method C2 provides a method of measuring the stiffness of the hose and tubing at the minimum
bend radius.

Gummi- und Kunststoffschläuche mit und ohne Einlage - Bestimmung der Biegsamkeit und Steifigkeit - Teil 1: Biegeprüfungen bei Umgebungstemperatur (ISO 10619-1:2017)

In diesem Dokument werden drei Verfahren zur Bestimmung der Biegsamkeit von Gummi- und Kunststoffschläuchen mit oder ohne Einlage (Verfahren A1, B und C1), bei denen die Verformung des Schlauchs mit oder ohne Einlage gemessen wird, und zwei Verfahren zum Messen der Steifigkeit (Verfahren A2 und C2) festgelegt, bei denen die erforderliche Kraft zum Biegen von Gummi- oder Kunststoffschläuchen mit oder ohne Einlage bis zu einem festgelegten Radius bei Umgebungstemperatur gemessen wird.
Die Verfahren A1 und A2 sind für Gummi- und Kunststoffschläuche mit und ohne Einlage mit einem Innendurchmesser bis einschließlich 80 mm geeignet.
Das Verfahren A1 erlaubt die Messung der Biegsamkeit des Schlauchs mit oder ohne Einlage, indem die Verringerung des Außendurchmessers beim Zusammendrücken des Schlauchs zwischen zwei Platten ermittelt wird.
Bei Verfahren A2 wird eine Einrichtung zum Messen der Kraft angewendet, die erforderlich ist, um beim Zusammendrücken des Schlauchs mit oder ohne Einlage zwischen zwei Platten einen festgelegten Biegeradius zu erreichen. Die Prüfung kann bei einem festgelegten Innendruck durchgeführt werden.
Verfahren B ist für Gummis- und Kunststoffschläuche mit und ohne Einlage mit einem Innendurchmesser bis einschließlich 100 mm geeignet und bietet eine Möglichkeit zur Bewertung des Verhaltens von Schläuchen mit und ohne Einlagen beim Biegen um einen Dorn. Der zuletzt verwendete Dorndurchmesser kann als kleinster Biegeradius des Schlauchs mit und ohne Einlagen angesehen werden. Da dieser Wert durch die Verringerung des Außendurchmessers bestimmt wird, kann er als Maß für die Biegsamkeit des Schlauchs mit und ohne Einlagen angewendet werden. Der zu untersuchende Schlauch mit und ohne Einlagen kann ohne Druck oder unter Druck oder unter Vakuum geprüft werden, und er kann, wenn eine Schlauchkrümmung vorhanden ist und eine entsprechende Anforderung besteht, in Richtung der Schlauchkrümmung oder entgegen der Richtung der Schlauchkrümmung geprüft werden.
Die Verfahren C1 und C2 sind für Gummi- und Kunststoffschläuche mit und ohne Einlagen mit einem Innendurchmesser von 100 mm und größer geeignet.
Verfahren C1 ermöglicht die Bestimmung der Biegsamkeit des Schlauchs mit und ohne Einlagen durch Biegen bis zum kleinsten Biegeradius.
Verfahren C2 bietet ein Verfahren zum Messen der Steifigkeit des Schlauchs mit und ohne Einlagen, der bis zum kleinsten Biegeradius gebogen wird.

Tuyaux et tubes en caoutchouc et en plastique - Mesurage de la flexibilité et de la rigidité - Partie 1: Essais de courbure à température ambiante (ISO 10619-1:2017)

ISO 10619-1:2017 spécifie trois méthodes de mesure de la flexibilité des tuyaux et des tubes en caoutchouc et en plastique (méthodes A1, B et C1), dans lesquelles la déformation du tuyau ou du tube est mesurée, et deux méthodes de mesure de la rigidité (méthodes A2 et C2) consistant à mesurer la force requise pour courber un tuyau ou un tube en caoutchouc ou en plastique à un rayon spécifique à température ambiante.
Les méthodes A1 et A2 conviennent pour des tuyaux et des tubes en caoutchouc ou en plastique de diamètre intérieur inférieur ou égal à 80 mm.
La méthode A1 permet de mesurer la flexibilité du tuyau ou du tube en mesurant la réduction du diamètre extérieur lorsque celui-ci est comprimé entre deux plaques.
La méthode A2 fournit un moyen de mesurer la force nécessaire pour obtenir un rayon de courbure spécifique lorsque le tuyau ou le tube est comprimé, comme entre deux plaques. L'essai peut être effectué à une pression interne spécifiée.
La méthode B convient pour des tuyaux et des tubes en caoutchouc et en plastique de diamètre intérieur inférieur ou égal à 100 mm, et fournit un moyen d'évaluer le comportement du tuyau ou du tube lorsqu'il est courbé autour d'un mandrin. Le diamètre final du mandrin utilisé peut être pris comme le rayon de courbure minimal du tuyau ou du tube. Étant donné que cette valeur est déterminée par la réduction du diamètre extérieur, elle peut être utilisée comme une mesure de la flexibilité du tuyau ou du tube. Le tuyau ou le tube soumis à essai peut être à la pression atmosphérique, sous pression ou sous vide et, si nécessaire, peut être soumis à essai suivant sa courbure naturelle ou contre celle-ci lorsqu'une telle courbure est présente.
Les méthodes C1 et C2 conviennent pour des tuyaux et des tubes en caoutchouc et en plastique de diamètre intérieur supérieur ou égal à 100 mm.
La méthode C1 fournit un moyen de déterminer la flexibilité du tuyau ou du tube au rayon minimal de courbure.
La méthode C2 fournit un moyen de mesurer la rigidité du tuyau ou du tube au rayon minimal de courbure.

Gumene in polimerne cevi ter cevovodi - Merjenje gibljivosti in togosti - 1. del: Upogibni preskus pri temperaturi okolja (ISO 10619-1:2017)

Ta dokument določa tri metode za merjenje gibljivosti gumenih ter polimernih cevi in cevovodov (metode A1, B in C1), s katerimi se meri deformacija cevi ali cevovoda, in dve metodi za merjenje togosti (metodi A2 in C2) z merjenjem sile, potrebne za upogibanje gumenih ali polimernih cevi in cevovodov na nek polmer pri temperaturi okolja.
Metodi A1 in A2 sta primerni za gumene ter polimerne cevi in cevovode z notranjim premerom 80 mm in več.
Metoda A1 omogoča merjenje gibljivosti cevi ali cevovoda z merjenjem zmanjšanja zunanjega premera, ko je cev stisnjena med dve plošči.
Metoda A2 določa način za merjenje sile, potrebne za doseganje nekega polmera upogibanja, kadar je cev ali cevovod stisnjen, npr. med dvema ploščama. Preskus je mogoče izvesti pri določenem notranjem tlaku.
Metoda B je primerna za gumene ter polimerne cevi in cevovode z notranjim premerom do vključno 100 mm ter omogoča oceno obnašanja cevi in cevovoda, ko sta upognjena okrog trna. Končni uporabljeni premer trna je mogoče privzeti kot najmanjši polmer upogibanja cevi. To vrednost določa zmanjšanje zunanjega premera, ki ga je mogoče uporabiti kot merilo gibljivosti cevi ali cevovoda. Preskušana cev ali cevovod je lahko pod tlakom ali ne oziroma pod vakuumom, po potrebi pa se preskusi vzdolž ukrivljenosti ali proti ukrivljenosti cevi ali cevovoda, če je taka ukrivljenost prisotna.
Metodi C1 in C2 sta primerni za gumene ter polimerne cevi in cevovode z notranjim premerom 100 mm in več.
Metoda C1 se uporablja za določanje gibljivosti cevi in cevovoda pri najmanjšem polmeru upogibanja.
Metoda C2 je metoda za merjenje togosti cevi in cevovoda pri najmanjšem polmeru upogibanja.

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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.
