Reinforced thermosetting moulding compounds - Specification for Sheet Moulding Compound (SMC) and Bulk Moulding Compound (BMC) - Part 2: Methods of test and general requirements

This part of prEN 14598 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of Sheet Moulding Compound (SMC) and Bulk Moulding Compound (BMC). Requirements for handling test material and for conditioning both of the test material before  moulding and of the specimens before testing are found here.
Procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made are given. Properties and test methods which are suitable and necessary to characterize  SMCs and BMCs are listed.
The properties have been selected from the general test methods in ISO 10350-1, Plastics - Acquisition and presentation of comparable single-point data - Part1: Moulding materials. Other test methods in wide use for or of particular significance to these compression and injection moulding materials are also included in this part of prEN 14598, as are the designatory  properties found in Part 1 : Designation and basis for specifications.
In order to obtain reproducible and comparable test results, it is necessary to use the methods of preparation and conditioning, test-specimens with the dimensions and the test procedures specified herein. Values determined will not necessarily be identical to those obtained using test-specimens of different dimensions or prepared using different procedures.

Verstärkte härtbare Formmassen - Spezifikation für Harzmatten (SMC) und faserverstärkte Pressmassen (BMC) - Teil 2: Prüfverfahren und allgemeine Anforderungen

In diesem Teil von EN 14598 werden die Verfahren zur Herstellung von Probekörpern und die Prüfverfahren
festgelegt, die zur Bestimmung der Eigenschaften von Harzmatten (SMC) und faserverstärkten Pressmassen
(BMC) anzuwenden sind. Er enthält Anforderungen an die Handhabung der zu prüfenden Formmassen und
das Konditionieren der zu prüfenden Formmassen vor der Formgebung und der Probekörper vor der Prüfung.
Angegeben werden Verfahren und Bedingungen zur Herstellung von Probekörpern und Verfahren zur
Bestimmung der Eigenschaften der Formmassen, aus denen diese Probekörper hergestellt werden.
Aufgeführt sind Eigenschaften und Prüfverfahren, die zur Charakterisierung von SMC und BMC geeignet und
notwendig sind.
Die Eigenschaften wurden aus den allgemeinen Prüfverfahren in ISO 10350-2, Plastics : Acquisition and
presentation of comparable single-point data . Part 2: Long-fibre-reinforced plastics, ausgewählt. Außerdem
sind in diesem Teil von EN 14598 weitere Prüfverfahren enthalten, die vielfach angewendet werden oder für
diese Formpress- und Spritzgießmassen von besonderer Bedeutung sind, während die kennzeichnenden
Eigenschaften in Teil 1 :Bezeichnungis zu finden sind.
Damit reproduzierbare und vergleichbare Prüfergebnisse erhalten werden, ist es notwendig, die Herstellungs-
und Konditionierverfahren, Probekörper mit den Maßen und Prüfverfahren anzuwenden, die in der vorliegen-
den Norm festgelegt sind. Die ermittelten Werte werden nicht notwendigerweise mit den Werten übereinstim-
men, die an Probekörpern mit davon abweichenden Maßen oder mit davon abweichenden Verfahren zur
Probekörperherstellung erhalten wurden.

La présente partie de l?EN 14598 spécifie les méthodes de préparation des éprouvettes ainsi que les
méthodes d?essai a utiliser pour la détermination des propriétés des mats préimprégnés (SMC) et des
mélanges a mouler en masse (BMC). Les exigences concernant la manipulation du matériau d?essai, ainsi
que le conditionnement du matériau d?essai avant moulage et des éprouvettes avant essai, sont décrites
ci-apres.
Elle donne les modes opératoires et les conditions a respecter pour la préparation des éprouvettes ainsi que
les modes opératoires relatifs au mesurage des propriétés des matériaux dont ces éprouvettes sont
constituées. La norme contient une liste des propriétés et des méthodes d?essai appropriées indispensables
pour caractériser les SMC et BMC.
Les propriétés sont choisies dans les méthodes d?essai générales indiquées dans l?EN ISO 10350-2,
"Plastiques - Acquisition et présentation de caractéristiques intrinseques comparables - Partie 2 : Plastiques
renforcés par de longues fibres". D?autres méthodes d?essai largement utilisées ou d?importance particuliere
pour ces matériaux de moulage par compression ou par injection sont également données dans la présente
partie de l?EN 14598, et le mode de désignation des propriétés figure dans la Partie 1 : Désignation.
Afin d?obtenir des résultats d?essai reproductibles et comparables, il est nécessaire d?utiliser les méthodes de
préparation et de conditionnement des éprouvettes, ainsi que les dimensions et les méthodes d?essai
spécifiées dans la norme. Les valeurs déterminées ne seront pas nécessairement identiques a celles
obtenues avec des éprouvettes de dimensions différentes ou préparées selon d?autres modes opératoires.
