Rubber, vulcanized or thermoplastic - Rubber sheets and rubber-coated fabrics - Determination of transmission rate of volatile liquids (gravimetric technique)

ISO 6179:2010 specifies two methods for determining, by measurement of the transmission rate, the permeability of rubber to volatile liquids diffusing into open air. It is applicable only to materials in sheet form and to coated fabrics having thicknesses between 0,2 mm and 3,0 mm. It is restricted to transmission rates of more than 0,1 g/m2/h. The methods are particularly useful for comparing the relative transmission rates of one liquid through different materials, or of several liquids through one material. Method A, with refilling, is used when testing mixtures of liquids which give different transmission rates. Method B, with no refilling, is used for a single-component liquid. A method for the determination of water vapour transmission rate is given in ISO 2528, Sheet materials — Determination of water vapour transmission rate — Gravimetric (dish) method.

Rubber, vulcanized or thermoplastic - Rubber sheets and rubber-coated fabrics - Determination of transmission rate of volatile liquids (gravimetric technique)

ISO 6179:2010 specifies two methods for determining, by measurement of the transmission rate, the permeability of rubber to volatile liquids diffusing into open air.

It is applicable only to materials in sheet form and to coated fabrics having thicknesses between 0,2 mm and 3,0 mm.

It is restricted to transmission rates of more than 0,1 g/m2/h.

The methods are particularly useful for comparing the relative transmission rates of one liquid through different materials, or of several liquids through one material.

Method A, with refilling, is used when testing mixtures of liquids which give different transmission rates.

Method B, with no refilling, is used for a single-component liquid.

A method for the determination of water vapour transmission rate is given in ISO 2528, Sheet materials — Determination of water vapour transmission rate — Gravimetric (dish) method.

Rubber, vulcanized or thermoplastic - Rubber sheets and rubber-coated fabrics - Determination of transmission rate of volatile liquids (gravimetric technique)

<p> La présente Norme internationale spécifie deux méthodes pour la détermination de la perméabilité du caoutchouc aux liquides volatils, à l'air libre, par mesurage du taux de transmission. Elle n'est applicable qu'aux matériaux en feuille et aux supports textiles revêtus ayant une épaisseur comprise entre 0,2 mm et 3,0 mm. Elle est limitée aux taux de transmission supérieurs à 0,1 g/M2.h. Les méthodes décrites sont particulièrement utiles pour comparer le taux relatif de transmission d'un liquide à travers différents matériaux ou de plusieurs liquides à travers un seul matériau. La méthode A, avec remplissages répétés, est utilisée pour des essais sur des mélanges de liquides ayant des taux de transmission différents. La méthode B, sans remplissages répétés, est utilisée pour un seul composant liquide. </p>

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
