Rubber and plastics hoses and tubing - Measurement of flexibility and stiffness - Part 1: Bending tests at ambient temperature (ISO 10619-1:2011)
ISO 10619-1:2011 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 to bend the hose or tubing when rubber or plastics hoses or tubing are bent 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 which 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 10619-1:2011)
Dieser Teil der ISO 10619 legt drei Verfahren zur Bestimmung der Biegsamkeit von Schläuchen (Verfahren A1, Verfahren B und Verfahren C1), bei denen die Verformung des Schlauchs gemessen wird, und zwei Verfahren zum Messen der Steifigkeit (Verfahren A2 und Verfahren C2) fest, bei denen die 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 Schläuche mit und ohne Einlage mit einem Innendurchmesser bis einschließlich 80 mm geeignet.
Das Verfahren A1 erlaubt die Messung der Biegsamkeit des Schlauchs, indem die Verringerung des Außen-durchmessers 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 zwischen zwei Platten einen festgelegten Biegeradius zu erreichen. Die Prüfung darf bei einem festgelegten Innendruck durchgeführt werden.
Verfahren B ist für Schläuche 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 darf als kleinster Biegeradius des Schlauchs mit und ohne Einlagen angesehen werden. Dieser Wert wird durch die Verringerung des Außendurchmessers bestimmt und kann als Maß für die Biegsamkeit des Schlauchs mit und ohne Einlagen angewendet werden. Der zu untersuchende Schlauch mit und ohne Einlagen darf ohne Druck oder unter Druck oder unter Vakuum geprüft werden, und er darf, 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 Schläuche mit und ohne Einlagen ab 100 mm 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 festgelegten 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 10619-1:2011)
L'ISO 10619-1:2011 spécifie trois méthodes de mesurage de la flexibilité des tuyaux et des tubes en caoutchouc et en plastique (méthode A1, méthode B et méthode C1) dans lesquelles la déformation du tuyau ou du tube est mesurée et deux méthodes de mesurage de la rigidité (méthode A2 et méthode 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 de 100 mm et plus.
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 ter polimerne cevi in cevovodi - Merjenje gibljivosti in togosti - 1. del: Upogibni preskus pri temperaturi okolja (ISO 10619-1:2011)
Ta del standarda ISO 10619 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 cevi pri upogibanju gumenih in 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 do vključno 80 mm. Pri metodi A1 se gibljivost cevi dobi ali cevovoda z merjenjem zmanjšanja zunanjega premera, kadar se cev stisne med dve plošči. Metoda A2 določa način za merjenje sile, potrebne za doseganje nekega polmera upogibanja, kadar je cev ali cevovod stisnjen, npr. med dve plošči. 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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
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.
ISO 10619-1 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee

Bending tests at ambient temperature
WARNING — Persons using this part of ISO 10619 should be familiar with normal laboratory practice.
This part of ISO 10619 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 part of ISO 10619 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 to bend the hose or tubing when rubber
or plastics hoses or tubing are bent 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 which 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.

4 Method A1
4.1 Apparatus
4.1.1 Apparatus, consisting of two guides A and B, guide A being fixed in a plane and guide B being movable
in that plane, parallel to and in line with, guide A [see Figure 1a)].
If it is desired to measure the force to attain the specified radius of curvature, this may be done, for example, by
means of pulleys and weights. Care shall be taken to minimize the effects of frictional resistance (see Figure 2).
4.2 Hose test pieces
4.2.1 Types and dimensions
The hose test pieces shall consist either of complete manufactured lengths of hose or suitable test lengths. If
the manufactured length is shorter than the length required for the test, hose test pieces of adequate length
shall be specially manufactured.
4.2.2 Number
Unless otherwise specified, two hose test pieces shall be tested.
4.3 Conditioning of hose test pieces
No test shall be carried out within 24 h of manufacture.
2 © ISO 2011 – All rights reserved
ISO 10619-1:2011(E)
For evaluations which are intended to be comparable, the test shall, as far as possible, be carried out after the
same time interval after manufacture. ISO 23529 shall be followed for time between sample manufacture and
testing.
Before testing, hose test pieces shall be conditioned for at least 16 h at a standard laboratory temperature and
humidity (see ISO 4671): this 16 h period may be part of the 24h interval after manufacture.
4.4 Test temperatures
The test shall be conducted at a standard laboratory temperature and humidity in accordance with ISO 23529.
4.5 Test procedure
4.5.1 If required, apply the specific test pressure or vacuum as given in the relevant product specification.
4.5.2 Measure and determine the average outside diameter, D, of the hose by means of a suitable measuring
instrument as specified in ISO 4671.
4.5.3 Draw two parallel and diametrically opposed lines along the length of the hose. If the hose has natural
curvature, one of the lines shall be on the outside of the curve. On each of these lines, mark a distance of
1,6 C + 2 D or 200 mm whichever is longer, where C is twice the minimum bend radius specified in the appropriate
specification, so that the marked distances are exactly opposed. This ensures a sufficient length for the bend
test and adequate support of the hose.
4.5.4 Separate guides A and B to a distance slightly less than 1,6 C + 2 D. Place the hose between the guides
so that the ends of the marked distances are parallel to the ends of the guides and remain in this position while
the guides are closed to a distance of C + 2 D (see Figure 1).
4.5.5 Check that the hose on each side is supported to a length of not
