Plastic piping systems - Mechanical joints between fittings and pressure pipes - Test method for leaktightness under negative pressure (ISO 3459:2022)

This document specifies two methods of testing for checking the leaktightness of assembled joints between mechanical fittings and plastic pressure pipes with diameters up to and including 63 mm. The test applies regardless of the design and material of the fitting used for jointing plastics pipe.
This test method is not applicable to fusion-welded joints.

Kunststoff-Rohrleitungssysteme - Mechanische Verbindungen zwischen Formstücken und Druckrohren - Prüfung der Dichtheit bei Unterdruck (ISO 3459:2022)

Dieses Dokument legt zwei Prüfverfahren zur Prüfung der Dichtheit von montierten Verbindungen zwischen mechanischen Formstücken und Kunststoffdruckrohren mit einem Durchmesser 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.

Systèmes de canalisations en matières plastiques - Assemblages mécaniques entre raccords et tubes sous pression - Méthode d'essai pour l'étanchéité sous pression négative (ISO 3459:2022)

Le présent document spécifie deux méthodes d’essai pour la vérification de l’étanchéité des assemblages entre raccords mécaniques et tubes sous pression en plastique dont le diamètre est inférieur ou égal à 63 mm. L’essai s’applique quelles que soient la conception et la matière du raccord utilisé pour le raccordement du tube plastique.
La présente méthode d’essai n’est pas applicable aux assemblages soudés par fusion.

Cevni sistemi iz polimernih materialov - Mehanski spoji med fitingi in tlačnimi cevmi - Metoda za preskus tesnjenja spojev, obremenjenih s podtlakom (ISO 3459:2022)

Ta dokument določa dve metodi preskušanja za preverjanje tesnjenja sestavljenih spojev med mehanskimi fitingi in plastičnimi tlačnimi cevmi s premerom do vključno 63 mm. Preskus velja ne glede na zasnovo in material fitinga, ki se uporablja za spajanje plastičnih cevi. Ta preskusna metoda se ne uporablja za talilno zvarjene spoje.

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).
