Textile-glass-reinforced plastics - Prepregs, moulding compounds and laminates - Determination of the textile-glass and mineral-filler content using calcination methods (ISO 1172:2023)
This document specifies two calcination methods for the determination of the textile glass and mineral filler content of glass-reinforced plastics:
— Method A: for the determination of the textile glass content when no mineral fillers are present.
— Method B: for the determination of the textile-glass and mineral-filler content when both components are present.
This document is applicable to the following types of material:
— prepregs made from yarns, rovings, tapes or fabrics;
— SMC, BMC and DMC moulding compounds;
— textile-glass-reinforced thermoplastic moulding materials and granules;
— filled or unfilled textile-glass laminates made with thermosetting or thermoplastic resins.
The methods do not apply to the following types of reinforced plastic:
— those containing reinforcements other than textile glass;
— those containing materials which do not completely burn off at the test temperature (for example, those based on silicone resin);
— those containing mineral fillers which degrade at temperatures below the minimum calcination temperature.
Textilglasverstärkte Kunststoffe - Prepregs, Formmassen und Laminate - Bestimmung des Textilglas- und Mineralfüllstoffgehalts mittels Kalzinierungsverfahren (ISO 1172:2023))
Dieses Dokument legt zwei Kalzinierungsverfahren zur Bestimmung des Textilglas- und Mineralfüllstoffgehalts von glasfaserverstärkten Kunststoffen fest:
Verfahren A: Zur Bestimmung des Textilglasgehalts, falls keine Mineralfüllstoffe vorhanden sind.
Verfahren B: Zur Bestimmung des Textilglas- und Mineralfüllstoffgehalts, wenn beide Bestandteile vorhanden sind.
Dieses Dokument ist auf folgende Materialarten anwendbar:
Prepregs aus Fäden, Rovings, Bändern oder Geweben;
SMC-, BMC- und DMC-Formmassen;
textilglasverstärkte thermoplastische Formmassen und Granulate;
gefüllte und ungefüllte Textilglaslaminate aus wärmehärtbaren oder thermoplastischen Harzen.
Die Verfahren sind auf folgende Arten von verstärkten Kunststoffen nicht anwendbar:
verstärkte Kunststoffe mit anderen Verstärkungsmaterialien als Textilglas;
verstärkte Kunststoffe, die Materialien enthalten, die bei der Prüftemperatur nicht vollständig verbrennen (z. B. Kunststoffe auf Silikonharzbasis);
verstärkte Kunststoffe mit Mineralfüllstoffen, die sich bei Temperaturen unter der Mindestkalzinierungstemperatur zersetzen.
ANMERKUNG Bei diesen Materialien kann ISO 11667 angewendet werden.
WARNUNG — Dieses Dokument enthält keine Einzelheiten von Vorsichtsmaßnahmen, die zur Erfüllung der Anforderungen an den Arbeits- und Gesundheitsschutz getroffen werden sollten. Die beschriebenen Prüfverfahren erfordern die Anwendung hoher Temperaturen und konzentrierter Säuren. Der Anwender dieses Dokuments ist dafür verantwortlich, die entsprechenden Arbeits- und Gesundheitsschutzbestimmungen zu befolgen.
Plastiques renforcés de verre textile - Préimprégnés, compositions de moulage et stratifiés - Détermination des taux de verre textile et de charge minérale par des méthodes calcination (ISO 1172:2023)
Le présent document spécifie deux méthodes par calcination pour la détermination des taux de verre textile et de charge minérale des plastiques renforcés de fibres de verre:
— Méthode A: pour la détermination du taux de verre textile en l’absence de charges minérales.
— Méthode B: pour la détermination du taux de verre textile et du taux de charge minérale en présence des deux composants.
Le présent document est applicable aux types de matériaux suivants:
— préimprégnés à base de fils, stratifils, rubans ou tissus;
— compositions de moulage: BMC, SMC, DMC;
— compositions de moulage et granulés de thermoplastiques renforcés de verre textile;
— stratifiés renforcés de verre textile tissé ou non tissé à base de résines thermodurcissables ou thermoplastiques.
Les méthodes ne sont pas applicables aux plastiques renforcés des types suivants:
— ceux contenant des renforts autres que le verre textile;
— ceux contenant certains matériaux qui ne se décomposent pas complètement à la température d’essai (par exemple ceux à base de résine silicone);
— ceux contenant des charges minérales qui se dégradent à une température inférieure à la température minimale de calcination.
NOTE Pour ces matériaux, l’ISO 11667 peut être utilisée.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.
