Rubber and plastics hoses and tubing - Measurement of flexibility and stiffness - Part 2: Bending tests at sub-ambient temperatures (ISO 10619-2:2017)

This document specifies two methods for measuring the stiffness and one method for the determination
of the flexibility of rubber and plastics hoses and tubing when they are bent to a specific radius at subambient
temperatures.
Method A is suitable for non-collapsible rubber and plastics hoses and tubing with a bore of up to and
including 25 mm. This method provides a means of measuring the stiffness of the hose or tubing when
the temperature is reduced from a standard laboratory temperature.
Method B is suitable for rubber and plastics hoses and tubing with a bore of up to 100 mm and provides
a means of assessing the flexibility of the hose or tubing when bent around a mandrel at a specified subambient
temperature. It can also be used as a routine quality control test.
Method C is suitable for rubber and plastics hoses and tubing with a bore of 100 mm and greater.
This method provides a means of measuring the stiffness of the hose and tubing at sub-ambient
temperatures. This method is only suitable for hoses and tubing which are non-collapsible

Gummi- und Kunststoffschläuche mit und ohne Einlage - Bestimmung der Biegsamkeit und Steifigkeit - Teil 2: Biegeprüfungen bei Temperaturen unterhalb der Umgebungstemperatur (ISO 10619-2:2017)

Dieses Dokument legt zwei Verfahren zur Messung der Steifigkeit und ein Verfahren zur Bestimmung der Biegsamkeit von Gummi  und Kunststoffschläuchen mit oder ohne Einlage fest, bei denen die Schläuche bei Temperaturen unterhalb der Umgebungstemperatur bis zu einem festgelegten Radius gebogen werden.
Verfahren A ist für nicht faltbare Schläuche mit einer Bohrung bis einschließlich 25 mm geeignet. Das Verfahren bietet eine Möglichkeit zum Messen der Steifigkeit des Schlauchs mit und ohne Einlagen, wenn die Temperatur ausgehend von einer Normlabortemperatur verringert wird.
Verfahren B ist für Schläuche mit und ohne Einlage mit einer Bohrung bis. einschließlich 100 mm geeignet und bietet eine Möglichkeit zur Bewertung der Flexibilität der Schläuche mit und ohne Einlagen, wenn sie bei einer festgelegten Temperatur unterhalb der Umgebungstemperatur um einen Biegedorn gebogen werden. Dieses Verfahren darf als Standardverfahren für Prüfungen zur Kontrolle der Qualität angewendet werden.
Verfahren C ist für Schläuche mit und ohne Einlagen mit einer Bohrung von 100 mm und größer geeignet. Das Verfahren bietet eine Möglichkeit zum Messen der Steifigkeit von Schläuchen mit und ohne Einlagen bei Temperaturen unterhalb der Umgebungstemperatur. Dieses Verfahren ist nur für Schläuche mit und ohne Einlage geeignet, die nicht faltbar sind.

Tuyaux et tubes en caoutchouc et en plastique - Mesurage de la flexibilité et de la rigidité - Partie 2: Essais de courbure à des températures inférieures à l'ambiante (ISO 10619-2:2017)

ISO 10619-2:2017 spécifie deux méthodes de mesure de la rigidité et une méthode de détermination de la flexibilité des tuyaux et des tubes en caoutchouc et en plastique lorsqu'ils sont courbés à un rayon spécifique à des températures inférieures à la température ambiante.
La méthode A convient pour des tuyaux et des tubes en caoutchouc et en plastique non aplatissables dont l'alésage est inférieur ou égal à 25 mm. Cette méthode fournit un moyen de mesurer la rigidité du tuyau ou du tube lorsque la température est réduite par rapport à une température normale de laboratoire.
La méthode B convient pour des tuyaux et des tubes en caoutchouc et en plastique dont l'alésage est inférieur à 100 mm et fournit un moyen pour évaluer la flexibilité du tuyau ou du tube lorsqu'il est courbé autour d'un mandrin à une température inférieure à la température ambiante spécifiée. Elle peut également être utilisée comme essai de routine de contrôle qualité.
La méthode C convient pour des tuyaux et des tubes en caoutchouc et en plastique dont l'alésage est supérieur ou égal à 100 mm. Cette méthode fournit un moyen de mesurer la rigidité du tuyau ou du tube à des températures inférieures à la température ambiante. Cette méthode ne convient que pour des tuyaux ou des tubes non aplatissables.

Gumene in polimerne cevi ter cevovodi - Merjenje gibljivosti in togosti - 2. del: Upogibni preskus pri temperaturah, nižjih od temperature okolja (ISO 10619-2:2017)

Ta dokument določa dve metodi za merjenje togosti in eno metodo za določitev gibljivosti gumenih ter polimernih cevi in cevovodov pri upogibanju na določen polmer pri temperaturah, nižjih od temperature okolja.
Metoda A je primerna za nezložljive gumene ter polimerne cevi in cevovode s premerom do
vključno 25 mm. Ta metoda se uporablja za merjenje togosti cevi ali cevovoda pri
temperaturi, nižji od standardne laboratorijske temperature.
Metoda B je primerna za gumene ter polimerne cevi in cevovode s premerom do vključno 100 mm ter se uporablja za oceno gibljivosti cevi ali cevovoda pri upogibanju okrog vretena pri temperaturah, nižjih od temperature okolja. Uporabiti jo je mogoče tudi kot rutinski preskus za nadzor kakovosti.
Metoda C je primerna za gumene ter polimerne cevi in cevovode s premerom najmanj 100 mm. Ta metoda se uporablja za merjenje togosti cevi in cevovoda pri temperaturah, nižjih od temperature okolja. Primerna je le za cevi in cevovode, ki niso zložljivi.

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).
