Elastomeric parts for parenterals and for devices for pharmaceutical use - Part 2: Identification and characterization (ISO 8871-2:2003)

ISO 8871-2:2003 specifies evaluation procedures applicable to elastomeric parts used for drug containers and medical devices in order to guarantee the product identity between the samples evaluated in the (suitability test) acceptance process and the current supplies. The physical and chemical test procedures specified in this part of ISO 8871 permit the determination of the typical characteristics of rubber materials, and may serve as a basis for agreements between manufacturer and user regarding the product consistency in subsequent supplies. An appropriate set of tests is selected, depending upon the type of rubber and its application.
This part of ISO 8871 does not specify other requirements for rubber materials. These are laid down in the relevant product standards.

Elastomere Teile für Parenteralia und für Geräte zur pharmazeutischen Verwendung - Teil 2: Identifizierung und Charakterisierung (ISO 8871-2:2003)

Dieser Teil von ISO 8871 legt Verfahren zur Anwendung bei elastomeren Teilen fest, die für Medikamentenbehälter und Medizinprodukte verwendet werden, um die Identität der laufenden Lieferungen des Produkts mit den im Zulassungsverfahren (Eignungsprüfung) bewerteten Proben sicherzustellen. Die durch diesen Teil von ISO 8871 zur Verfügung gestellten physikalischen und chemischen Prüfverfahren ermöglichen die Bestimmung der typischen Eigenschaften von Gummimaterialien und können als Grundlage für Vereinbarungen zwischen Hersteller und Anwender hinsichtlich der gleich bleibenden Eigenschaften des Produkts bei nachfolgenden Lieferungen dienen. Abhängig vom Typ des Gummis und seiner Anwendung ist eine geeignete Zusammenstellung von Prüfungen auszuwählen.
Dieser Teil von ISO 8871 legt keine Anforderungen an Gummimaterialien fest. Diese sind in den anwendbaren Produktnormen festgelegt.

Eléments en élastomère pour administration parentérale et dispositifs à usage pharmaceutique - Partie 2: Identification et caractérisation (ISO 8871-2:2003)

L'ISO 8871-2:2003 spécifie des modes opératoires d'évaluation applicables aux éléments en élastomère utilisés pour les articles de conditionnement des médicaments et les dispositifs médicaux afin de garantir que le produit livré est identique aux échantillons évalués lors du processus d'acceptation (de l'essai d'aptitude à l'emploi). Les modes opératoires d'essai des caractéristiques physiques et chimiques présentés dans l'ISO 8871-2:2003 permettent de déterminer les caractéristiques types des caoutchoucs et peuvent servir de base à des accords entre le fabricant et l'utilisateur en ce qui concerne la reproductibilité du produit lors des livraisons ultérieures. Un ensemble approprié d'essais est choisi en fonction du type de caoutchouc et de l'application.
L'ISO 8871-2:2003 ne spécifie pas les exigences ultérieures du caoutchouc; celles-ci sont données dans les normes appropriées du produit.

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 8871-2 was prepared by Technical Committee ISO/TC 76, Transfusion, infusion and injection equipment
for medical and pharmaceutical use.
Together with the other parts (see below), this part of ISO 8871 cancels and replaces ISO 8871:1990, which
has been technically revised.
ISO 8871 consists of the following parts, under the general title Elastomeric parts for parenterals and for
devices for pharmaceutical use:
 Part 1: Extractables in aqueous autoclavates
 Part 2: Identification and characterization
 Part 3: Determination of released-particle count
 Part 4: Biological requirements and test methods
 Part 5: Functional requirements and testing

ISO 8871-2:2003(E)
Introduction
The elastomeric parts specified in the various parts of this International Standard are produced from a material
which is usually called “rubber”. However, rubber is not a unique entity, since the composition of rubber
materials may vary considerably. The base elastomer and the type of vulcanization have a major influence on
the principle characteristics of an individual rubber material, as do additives such as fillers, softeners and
pigments. These may have a significant effect on the overall properties. The effectiveness, purity, stability and
safe handling of a drug preparation may be affected adversely during manufacture, storage and administration
if the rubber part used has not been properly selected and validated (approved).

3 Tests
3.1 General
Rubber is a complex material and not generally definable. The only property which all elastomeric materials
have in common is a special type of resilience or elasticity. When a strip of rubber is stretched, it will extend
by up to many times its original length without breaking. On release of the stretching force, it snaps back to its
original size and shape virtually unaltered. Similarly, one can squeeze it, twist it or distort it in any direction
comparatively easily, and it will spring back again to its original shape unchanged.
ISO 8871-2:2003(E)
Owing to its three-dimensional network, achieved by chemical cross-linking of the polymer chains during
vulcanization, rubber is practically insoluble in solvents such as tetrahydrofuran, although considerable
reversible swelling may occur; this characteristic differentiates rubber from pseudo-elastic materials, such as
poly(vinyl chloride) and certain thermoplastic elastomers.
In view of the complexity of rubber, the identity of a given elastomeric material cannot be verified just by
applying a single physical or chemical test, and a set of tests is needed for reliable identification.
The manufacturer shall guarantee that all elastomeric parts of current supplies have been produced from the
same formulation and that they exhibit the same characteristics as the samples which have been given to the
user first and the suitability of which has been proved.
3.2 Hardness
Hardness shall be determined in accordance with ISO 48.

Density shall be determined in accordance with the procedure described in IS
