Thermoplastics valves - Torque - Test method (ISO/DIS 8233:2020)
Armaturen aus Thermoplasten - Drehmoment - Prüfverfahren (ISO/DIS 8233:2020)
Diese Internationale Norm legt ein Prüfverfahren zur Bestimmung des Drehmoments zum Öffnen und Schließen von Armaturen aus Thermoplasten fest.
Diese Internationale Norm ist auf alle Typen von Armaturen aus Thermoplasten anwendbar, die für den Transport von Flüssigkeiten nach ISO 16135, ISO 16136, ISO 16138, ISO 16139, ISO 21787 vorgesehen sind.
Die Beziehung zwischen dem Drehmoment und dessen möglicher Erhöhung nach längerem Gebrauch der Armatur bei bestimmten Arbeitsbedingungen oder Materialverschleiß/chemischer Aggression ist nicht festgelegt.
ANMERKUNG Bezüglich der chemischen Aggression der Materialien ist in ISO/TR 10358 [1] eine Sammlung von Daten über die Dauerprüfung angegeben, die erforderlich ist, um die Fähigkeit handbetätigter Armaturen aus Thermoplasten zu bestätigen, einem längeren Gebrauch bei wiederholtem Öffnen und Schließen standzuhalten; Informationen sind in ISO 8659 [2] angegeben.

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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/
iso/ foreword .html.
This document was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for
the transport of fluids, Subcommittee SC 07, Valves and auxiliary equipment of plastics materials.
This second edition cancels and replaces the first edition (ISO 8233:1988), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— updating of the normative references and terms and definitions clauses;
— specification of the type of valve in the test report and explanation for the opening torque.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/ members .html.

Introduction
The aim of this document is to establish certain basic requirements for the torque testing of plastics
valves to ensure that uniform test methods are adopted. This document is intended to be considered in
conjunction with any specific requirements in particular product standards applicable to the individual
types of valves.
