Rubber- or plastic-coated fabrics - Determination of resistance to liquids

This European Standard describes two methods of evaluating the resistance of fabrics coated with plastics or with vulcanised rubber to the action of liquids by measurement of selected properties of the materials before and after immersion in selected liquids.
The methods described in this European Standard concern the following determinations :
a) Method 1 : Change of physical properties after immersion in test liquids
b) Method 2 : Change of physical properties after exposure and evaporation of volatile test liquids.

Supports textiles revêtus de caoutchouc ou de plastique - Détermination de la résistance aux liquides

La présente Norme européenne décrit deux méthodes pour évaluer la résistance des supports textiles revêtus de plastique ou de caoutchouc vulcanisé à l'action des liquides en mesurant des propriétés choisies des matériaux avant et après trempage dans des liquides sélectionnés.
Les méthodes décrites dans cette norme européenne concernent les déterminations suivantes :
a) méthode 1 : Changement de propriétés physiques après trempage dans des liquides d'essai ;
b) méthode 2 : Changement de propriétés physiques après exposition et évaporation de liquides d'essai volatils.

Rubber- or plastics-coated fabrics - Standard atmospheres for conditioning andtesting (ISO 2231:1989)EN ISO 2286-1
Rubber- or plastics-coated fabrics - Determination of roll characteristics -Part 1: Methods for determination of length, width and net mass (ISO 2286-1:1998)3 PrincipleThis European Standard provides a procedure for exposing test specimens to the influence ofliquids under defined conditions of temperature and time. Selected properties are determinedaccording to the relevant European or International Standards. Test specimens are thenimmersed in selected liquid(s) and the properties determined again. The percentage change orthe values before and after immersion are measures of the resistance of the material to theselected liquid(s).4 Test liquids for methods 1 and 2As commercial liquids may not have an entirely constant composition, a standard immersionliquid consisting of well-defined chemical compounds or mixture of compounds shall be used.Some suitable liquids are recommended in annex A (informative).When a commercial liquid is used, the test report shall mention all the available informationabout its origin, composition, properties, e.g. viscosity, aniline point, etc.,
and batch number.SIST EN 12759:2001

For test purpose, it is usually desirable to use the liquid(s) with which the coatedfabric will come into contact during use. When testing to determine the effect of chemicalsolutions, the concentration of the solutions should be appropriate to the proposed application.WARNING
Appropriate safety precautions should be taken when preparing and handling testliquids, especially those known to be toxic, corrosive or flammable. Products giving off fumesshould be handled only under an efficiently ventilated hood, corrosive products should not beallowed to come into contact with the skin or ordinary clothing, and flammable productsshould be kept away from any source of ignition.In addition, attention is drawn to the possible damaging of test equipment (e.g. clamps orjaws) when using corrosive test liquids.5 Test conditions for methods 1 and 25.1 TemperatureUse a test temperature approximating those found during use. Maintain the testtemperature (T) at T
2 °C.Unless otherwise specified or agreed upon, test temperature (T) should be one of the standardtemperatures given in annex B.5.2 Immersion periodThe following immersion periods are recommended :22 h
0,25 h ;
46 h
0,25 h ;
72 h
2 h ;
168 h
2 h ;
multiples of 7 days
2 h.NOTE
When testing for changes in physical properties, it is advisable to use such a period ofimmersion that equilibrium is allowed to be reached. To define this equilibrium, it isrecommended to carry out preliminary measurements with several periods of immersion,recording the results as a function of time. Whenever practicable, the total immersion periodshould be chosen to extend far beyond the point of maximum variation.5.3 LightImmersion tests shall be conducted in the absence of direct light.5.4 Time lapse between manufacturing and testingThe minimum time lapse between manufacturing and testing shall be 16 h.SIST EN 12759:2001

e.g glass bottle, tube, of such dimensions that the test specimens remaincompletely immersed in the specified volume of test liquid and are freely exposed on allsurfaces without restraint. At temperatures near the boiling point of the test liquid, fit thevessel with a reflux condenser or other suitable means of minimising evaporation of the testliquid, instead of the stopper.8 Method 1 - Change of physical properties after immersion in test liquid.8.1 Preparation of test specimensSelect properties that are considered relevant to the end-use (for example : tensile strength,coating adhesion, mass per unit area, tear resistance, low-temperature properties, etc.).Cut in the usable width of the roll (according to EN ISO 2286-1) two sets of test specimensfor each property as specified in the relevant EN or ISO standard.Condition all the test specimens according to clause 6.8.2 Determination of original properties before immersionDetermine the selected properties on the first set of test specimens using the respective EN orISO standards (see clause 2).8.3 Immediate properties after immersion8.3.1 ImmersionPlace the test specimens, suitably separated, in a vessel as described in clause 7, with avolume of test liquid (clause 4) that shall be at least 15 times the combined volume of the testspecimens and sufficient to keep them totally immersed. If the conditions of test do notnecessitate the use of a reflux condenser, stopper the vessel. Maintain the test liquid
at thetest temperature (T) during all the exposure period, within a tolerance of
2 °C.SIST EN 12759:2001
