27、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 represent
28、ed 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 t
29、his 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
30、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 de
31、velopment 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.For an explanation on the voluntary nat
32、ure of standards, the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISOs adherence to the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following URL: www.iso.org/iso/foreword.html.This docume
33、nt was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 1, Rubber and plastics hoses and hose assemblies.This second edition cancels and replaces the first edition (ISO 10619-1:2011), of which it constitutes a minor revision. The changes compared to the previous
34、 edition are as follows: the unit used in the formula to calculate the flexural stiffness in 8.4 and 8.5 has been changed.A list of all parts in the ISO 10619- series can be found on the ISO website.iv ISO 2017 All rights reservedBS EN ISO 106191:2018INTERNATIONAL STANDARD ISO 10619-1:2017(E)Rubber
35、and plastics hoses and tubing Measurement of flexibility and stiffness Part 1: Bending tests at ambient temperatureWARNING Persons using this document should be familiar with normal laboratory practice. This document does not purport to address all of the safety problems, if any, associated with its
36、 use. It is the responsibility of the user to establish appropriate safety and health practices.1 ScopeThis 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
37、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.Met
38、hod 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 be
39、tween 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 fina
40、l 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 unde
41、r 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 t
42、he 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.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of
