Rubber and plastics hoses and tubing - Measurement of flexibility and stiffness - Part 2 : bending tests at sub-ambient temperatures

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.

Rubber and plastics hoses and tubing - Measurement of flexibility and stiffness - Part 2 : bending tests at sub-ambient temperatures

Le présent document spécifie, pour les tuyaux ou tubes en caoutchouc ou en plastique soumis à des essais de courbure à des températures inférieures à la température ambiante, deux méthodes de mesurage de la rigidité (Méthode A, et Méthode C) et une méthode de détermination de la flexibilité (Méthode B) , lorsque ceux-ci sont courbés à un rayon donné. Il définit pour chaque méthode l'appareillage, les éprouvettes, la température d'essai, le mode opératoire, et le contenu du rapport d'essai. Pour les méthodes A et C, il définit également comment exprimer les résultats obtenus.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
