Plastics - Methods of test for the determination of the effects of immersion in liquid chemicals (ISO 175:2010)
ISO 175:2010 specifies a method of exposing test specimens of plastic materials, free from all external restraint, to liquid chemicals, and methods for determining the changes in properties resulting from such immersion. It does not cover environmental stress cracking (ESC) which is dealt with by the various parts of ISO 22088.
It only considers testing by immersion of the entire surface of the test specimen.
It is applicable to all solid plastics that are available in the form of moulding or extrusion materials, plates, tubes, rods or sheets having a thickness greater than 0,1 mm. It is not applicable to cellular materials.
Kunststoffe - Prüfverfahren zur Bestimmung des Verhaltens gegen flüssige Chemikalien (ISO 175:2010)
Diese Internationale Norm legt ein Verfahren zur Lagerung von Probekörpern aus Kunststoffen ohne
äußere Beanspruchungen in flüssigen Chemikalien fest sowie Verfahren zur Bestimmung der Änderungen
von Eigenschaften, die sich aus dieser Lagerung ergeben. Nicht erfasst wird die umweltbedingte
Spannungsrissbildung, die in den unterschiedlichen Teilen der ISO 22088 beschrieben wird.
1.2 Diese Norm berücksichtigt nur die Prüfung durch Eintauchen der gesamten Oberfläche des
Probekörpers.0F

ANMERKUNG Zur Veranschaulichung einer nur teilweisen oder selten auftretenden Feuchtigkeitseinwirkung auf
Kunststoffe ist dieses Verfahren möglicherweise ungeeignet.
1.3 Die vorliegende Norm ist auf alle festen Kunststoffe anwendbar, die aus Form- oder
Strangpressmaterialien bestehen oder in Form von Platten, Rohren, Stäben oder Folien vorliegen und dicker
als 0,1 mm sind. Auf Schaumstoffmaterialien ist sie nicht anwendbar.
Plastiques - Méthodes d'essai pour la détermination des effets de l'immersion dans des produits chimiques liquides (ISO 175:2010)
L'ISO 175:2010 spécifie une méthode d'exposition d'éprouvettes en plastique exemptes de toute contrainte extérieure à des produits chimiques liquides, ainsi que des méthodes de détermination des variations des caractéristiques résultant d'une telle exposition. Elle ne concerne pas la fissuration sous contrainte dans un environnement donné (ESC) qui est traitée dans les différentes parties de l'ISO 22088.
Elle n'envisage que l'essai par immersion sur toute la surface de l'éprouvette.
Elle est applicable à tous les plastiques compacts se présentant sous forme de matières à mouler ou à extruder, de plaques, tubes, joncs ou feuilles ayant une épaisseur supérieure à 0,1 mm. Elle n'est pas applicable aux matériaux alvéolaires.
Polimerni materiali - Preskusne metode za ugotavljanje učinkov pri potapljanju v tekoče kemikalije (ISO 175:2010)
Ta mednarodni standard določa metodo izpostavljanja preskusnih vzorcev polimernih materialov brez zunanjih omejitev tekočim kemikalijam in metode za določevanje sprememb v lastnostih zaradi takega potapljanja. Ne zajema razpokanja zaradi okoljskih vplivov (ESC), ki ga obravnavajo različni deli ISO 22088. Obravnava le preskušanje s potapljanjem celotne površine preskušanca.

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 175 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 6, Ageing, chemical
and environmental resistance.
This third edition cancels and replaces the second edition (ISO 175:1999), of which it constitutes a minor
revision.

Introduction
Because of their varied applications, plastics are frequently brought into contact with liquids such as chemical
products, motor fuels, lubricants, etc., and, possibly, with their vapours.
Under the action of a liquid, a plastic material may be subjected to several phenomena which may occur
simultaneously. On the one hand, absorption of liquid and extraction of constituents soluble in the liquid may
occur. On the other hand, a chemical reaction, often resulting in a significant change in the properties of the
plastic, may occur. The equilibrium swelling ratio for a crosslinked polymer in a liquid that is a solvent for the
same but non-crosslinked polymer is a measure of the degree of crosslinking.
The behaviour of plastics in the presence of liquids can be determined only under arbitrarily fixed conditions
aimed at making comparisons between different materials. The choice of test conditions (nature of the liquid,
immersion temperature and immersion time), as well as the choice of the properties in which changes are to
be measured, depends on the eventual application of the plastic under test.
It is not possible, however, to establish any direct correlation between the experimental results and the
behaviour of the plastic in service. These tests do, nevertheless, permit a comparison to be made of the
behaviour of different plastic materials under specified conditions, thus allowing an initial evaluation of their
behaviour in relation to certain groups of liquids.
NOTE In view of its special importance, the particular case of the determination of the quantity of water absorbed is
