Plastics - Styrene/acrylonitrile (SAN) moulding and extrusion materials - Part 2: Preparation of test specimens and determination of properties (ISO 4894-2:1995)

Cancels and replaces the first edition (1981). Specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of SAN moulding and extrusion materials. Gives requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing. Gives procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made. Lists properties and test methods which are suitable and necessary to characterize SAN moulding and extrusion materials.

Kunststoffe - Styrol/Acrylnitril (SAN)-Formmassen - Teil 2: Herstellung von Probekörpern und Bestimmung von Eigenschaften (ISO 4894-2:1995)

Dieser Teil von ISO 4894 legt die Bedingungen zur Herstellung von Probeko(rpern und die zur Bestimmung der Eigenschaften von SAN-Formmassen anzuwendenden Pru(fverfahren fest. Anforderungen an die Behandlung des Probenmaterials und fu(r das Konditionieren des Probenmaterials vor der Herstellung der Probeko(rper und der Probeko(rper vor der Pru(fung sind ebenfalls enthalten. Verfahren und Bedingungen fu(r die Herstellung der Probeko(rper und Vorschriften fu(r die Bestimmung der Eigenschaften der Formmasse, aus der die Probeko(rper hergestellt werden, sind angegeben.

Plastiques - Styrène/acrylonitrile (SAN) pour moulage et extrusion - Partie 2: Préparation des éprouvettes et détermination des propriétés (ISO 4894-2:1995)

La présente partie de l'ISO 4894 prescrit les méthodes de préparation des éprouvettes et les méthodes d'essai à appliquer pour déterminer les propriétés des SAN pour moulage et extrusion. Elle indique les exigences requises lors de la manipulation du matériau pour essai, ainsi que lors du conditionnement dudit matériau avant moulage et des éprouvettes avant l'essai. Elle précise les modes opératoires et les conditions nécessaires à la préparation des éprouvettes, ainsi que les modes opératoires de mesurage des propriétés des matériaux à partir desquels ces éprouvettes sont fabriquées. Elle fournit également une liste des propriétés et des méthodes d'essai appropriées et nécessaires à la caractérisation des SAN pour moulage et extrusion. Les propriétés ont été choisies à partir des méthodes d'essai générales données dans l'ISO 10350. D'autres méthodes d'essai, présentant une importance particulière ou largement utilisées dans le cas de ces matériaux pour moulage et extrusion, sont également incluses dans la présente partie de l'ISO 4894, de même qu'elles figurent dans les propriétés de désignation de l'ISO 4894-1.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
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. IS0
collaborates closely with the International Electrotechnical Commission
(I EC) on all matters of electrotechnical standardization.
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.
International Standard IS0 4894-2 was prepared by Technical Committee
lSO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materials.
This second edition cancels and replaces the first edition
an includes the following changes:
