Kunststoff-Rohrleitungssysteme - Mechanische Verbindungen zwischen Formstücken und Druckrohren - Prüfung der Dichtheit bei Unterdruck (ISO/DIS 3459:2021)
Diese Internationale Norm legt zwei Prüfverfahren zur Prüfung der Dichtheit von montierten Verbindungen zwischen mechanischen Formstücken und Kunststoffdruckrohren mit Durchmessern bis einschließlich 63 mm fest. Die Prüfung ist anwendbar unabhängig von Konstruktion und Werkstoff des Formstückes, das zum Verbinden von Kunststoffrohren verwendet wird.
Dieses Prüfverfahren ist nicht für Schmelzschweißverbindungen anwendbar.

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 5, General properties of pipes, fittings and valves of plastic
materials and their accessories -- Test methods and basic specifications.This third edition cancels and replaces the second edition (ISO 3459:2015), which has been technically
revised.The main changes compared to the previous edition are as follows:
— references to diameters > 63 mm are deleted;
— a change in vacuum pressure that can be considered to be leak tight is introduced;
— editorial changes have been introduced.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.iv © ISO 2021 – All rights reserved
