Rubber and plastics hoses and tubing - Measurement of flexibility and stiffness - Part 2: Bending tests at sub-ambient temperatures (ISO 10619-2:2021)
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 sub-ambient 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 sub-ambient 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 10619-2:2021)
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 Gummi- und Kunststoffschläuche mit oder ohne Einlage mit einer Bohrung bis einschließlich 25 mm geeignet. Das Verfahren bietet eine Möglichkeit zum Messen der Steifigkeit des Schlauchs mit und ohne Einlage, wenn die Temperatur ausgehend von einer Normlabortemperatur verringert wird.
Verfahren B ist für Gummi- und Kunststoffschläuche mit und ohne Einlage mit einer Bohrung bis 100 mm geeignet und bietet eine Möglichkeit zur Bewertung der Biegsamkeit der Schläuche mit und ohne Einlage, wenn sie bei einer festgelegten Temperatur unterhalb der Umgebungstemperatur um einen Biegedorn gebogen werden. Dieses Verfahren kann auch als Routineprüfung in der Qualitätslenkung angewendet werden.
Verfahren C ist für Gummi- und Kunststoffschläuche mit und ohne Einlage mit einer Bohrung von 100 mm und größer geeignet. Das Verfahren bietet eine Möglichkeit zum Messen der Steifigkeit der Schläuche mit und ohne Einlage bei Temperaturen unterhalb der Umgebungstemperatur. Dieses Verfahren ist nur für Schläuche mit und ohne Einlage geeignet, die nicht faltbar sind.
WARNUNG - Die in diesem Dokument beschriebene Prüfung sollte von erfahrenem Personal durchgeführt werden. In diesem Dokument werden nicht alle Sicherheitsprobleme behandelt, die bei Anwendung der Norm auftreten können. Es liegt in der Verantwortlichkeit des Anwenders, geeignete Gesundheits- und Sicherheitsmaßnahmen festzulegen.
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 10619-2:2021)
Le présent document 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.

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).
