Plastic piping systems - Mechanical joints between fittings and pressure pipes - Test method for leaktightness under negative pressure (ISO 3459:2015)

ISO 3459:2015 specifies two methods of testing for checking the leaktightness of assembled joints between mechanical fittings and plastic pressure pipes 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 Fittings und Druckrohren - Prüfung der Dichtheit bei Unterdruck (ISO 3459:2015)

Diese Internationale Norm legt zwei Prüfverfahren zur Prüfung der Dichtheit von montierten Verbindungen, (ausgenommen Schmelzschweißverbindungen) zwischen mechanischen Formstücken und thermoplastischen Druckrohren mit einem Durchmesser bis einschließlich 63 mm fest. Die Prüfung ist anwendbar unabhängig von Konstruktion und Werkstoff des Formstückes, das zum Verbinden thermoplastischer Rohre verwendet wird.

Systèmes de canalisations en matières plastiques - Assemblages mécaniques entre raccords et tubes sous pression - Méthode d'essai pour l'étanchéité sous pression négative (ISO 3459:2015)

L'ISO 3459:2015 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. Cette méthode est applicable quelles que soient la conception et la matière du raccord utilisé pour le raccordement des tubes en plastique.
La présente méthode d'essai n'est pas applicable aux assemblages soudés par fusion.

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
