Rubber and plastics hoses and hose assemblies - Determination of permeability to gas (ISO 4080:2009)
This part of ISO 8253 specifies relevant test signal characteristics, requirements for free, diffuse, and quasi-free sound fields, and procedures for sound field audiometry using pure tones, frequency-modulated tones or other narrow-band test signals presented by means of one or more loudspeakers. The primary purpose is the determination of hearing threshold levels in the frequency range 125 Hz to 8 000 Hz, but this range can be extended to 20 Hz to 16 000 Hz. This part of ISO 8253 does not include specifications for the use of hand-held loudspeakers. Speech as a test signal is not covered. The purpose of this part of ISO 8253 is to ensure that tests of hearing, using sound field audiometry, give as high a degree of accuracy and reproducibility as possible. Examples of graphical representations of the results are given in Annex A.
Gummi- und Kuntstoffschläuche und -schlauchleitungen - Bestimmung der Gasdurchlässigkeit (ISO 4080:2009)
In dieser Internationalen Norm werden drei Verfahren zur Bestimmung des Gasvolumens festgelegt, das in
einer festgelegten Zeit durch einen Gummi- oder Kunststoffschlauch oder eine Schlauchleitung diffundiert.
Verfahren 1: Bestimmung der Durchlässigkeit für das Prüfgas durch den gesamten Schlauch oder eine
Schlauchlänge mit oder ohne Einlage, mit Ausnahme der Endarmaturen. Die Durchlässigkeit wird bezogen
auf die Länge des Schlauchs mit oder ohne Einlage berechnet.
Verfahren 2: Bestimmung der Durchlässigkeit für das Prüfgas im Übergangsbereich Schlauch/Armatur.
Dieses Verfahren dient zur Bestimmung der Durchlässigkeitskennwerte von Schläuchen mit ungeprickter
Außenschicht, wenn das Gas normalerweise von der textilen Einlage hin zu den abgeschnittenen Enden
austritt. Die Durchlässigkeit wird bezogen auf die Länge des Schlauchs berechnet.
Verfahren 3: Präzise Bestimmung der Durchlässigkeit eines Schlauchs oder einer Schlauchleitung für das
Prüfgas. Die Durchlässigkeit wird bezogen auf die Oberfläche der Schlauchinnenschicht berechnet.
Die Verfahren sind nur mit Prüfgasen anwendbar, die in Wasser nicht löslich sind.
ANMERKUNG 1 Obwohl die Ergebnisse der Verfahren 1 und 2 in den gleichen Einheiten angegeben werden, sind die
für geprickte und ungeprickte Schläuche mit gleichen Anwendungsbereichen ermittelten Ergebnisse nicht unbedingt
vergleichbar, da für die beiden Verfahren unterschiedliche Prüfzeiten festgelegt sind, weswegen von unterschiedlichen
Durchlässigkeiten ausgegangen werden kann.
ANMERKUNG 2 Verfahren 3 ist das zu bevorzugende Verfahren.
Tuyaux et flexibles en caoutchouc et en plastique - Détermination de la perméabilité au gaz (ISO 4080:2009)
L'ISO 4080:2009 spécifie trois méthodes pour la détermination du volume de gaz diffusant à travers un tuyau ou une longueur de tube en caoutchouc ou en plastique pendant une durée déterminée.
Méthode 1: Pour déterminer la perméabilité de l'ensemble d'un tuyau ou d'une longueur de tube, à l'exclusion des raccords d'extrémité, au gaz d'essai. La perméabilité est calculée par rapport à la longueur du tuyau ou du tube.
Méthode 2: Pour déterminer la perméabilité à l'interface tuyau/raccordement. Cette méthode est utilisée pour évaluer les caractéristiques de perméabilité des tuyaux à revêtement non piqueté lorsque le gaz sort de l'armature textile aux extrémités coupées. La perméabilité est calculée par rapport à la longueur du tuyau.
Méthode 3: Pour déterminer précisément la perméabilité d'un tuyau ou d'un flexible au gaz d'essai. La perméabilité est calculée par rapport à l'aire du revêtement du tuyau.
Les méthodes sont applicables uniquement aux gaz qui sont insolubles dans l'eau.
Gumene in polimerne cevi ter cevni priključki - Ugotavljanje prepustnosti za pline (ISO 4080:2009)
Ta del ISO 8253 določa ustrezne lastnosti preskusnega signala, zahteve za prosto, difuzno in skoraj prosto zvočno polje ter postopke za avdiometrijo zvočnega polja z uporabo čistih tonov, frekvenčno moduliranih tonov ali drugih ozkopasovnih preskusnih signalov, ki jih proizvaja eden ali več zvočnikov. Glavni namen je ugotavljanje ravni slušnega praga v frekvenčnem območju med 125 Hz in 8.000 Hz, vendar se lahko razširi na območje med 20 Hz in 16.000 Hz. Ta del ISO 8253 ne vključuje specifikacij za uporabo ročnih zvočnikov. Govor kot preskusni signal ni vključen. Namen tega dela ISO 8253 je zagotoviti, da so preskusi sluha z uporabo avdiometrije z zvočnim poljem čim bolj natančni in ponovljivi. Primeri grafičnih prikazov rezultatov so podani v Dodatku A.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 4080 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee
SC 1, Hoses (rubber and plastics).
This fourth edition cancels and replaces the third edition (ISO 4080:1991), which has been technically revised
to clarify the test method procedures and to standardize the units in the expression of results clause for
method 1 and method 2. It also incorporates the Technical Corrigendum ISO 4080:1991/Cor.2:1998.

INTERNATIONAL STANDARD ISO 4080:2009(E)
Rubber and plastics hoses and hose assemblies —
Determination of permeability to gas
WARNING — Persons using this International Standard should be familiar with normal laboratory
practice. This standard does not purport to address all of the safety problems, if any, associated with
its use. It is the responsibility of the user to establish appropriate safety and health practices and to
ensure compliance with any national regulatory conditions.
1 Scope
This International Standard specifies three methods for the determination of the volume of gas diffusing
through a rubber or plastics hose or length of tubing in a specified time.
Method 1: For determining the permeability of the complete hose or length of tubing, excluding end-
fittings, to the test gas. The permeability is calculated with respect to the length of the hose or tubing.
Method 2: For determining the permeability at the hose/fitting interface. This method is used when
determining the permeability characteristics of hoses with an unpricked cover, when the gas usually
issues from the textile reinforcement at the cut ends. The permeability is calculated with respect to the
length of the hose.
Method 3: For determining precisely the permeability of a hose or hose assembly to the test gas. The
permeability is calculated with respect to the surface area of the hose lining.
The methods are applicable only to gases which are insoluble in water.
NOTE 1 Although the results are expressed in the same units for methods 1 and 2, the results obtained will not
necessarily be comparable in the case of unpricked and pri
