Reinforced thermoplastic moulding compounds - Specification for GMT - Part 3: Specific requirements
1.1 This Part 3 of prEN 13677, is a specification for thermoplastic compression mouldable sheet consisting of textile glass mat reinforced polypropylene or equivalent products, as described in Part 1 of this specification.
The specification defines those parameters which shall be specified plus other parameters which may be specified if required for a particular application or processing method.
1.2 The specification does not define absolute or nominal values for any parameter. The value of a specified parameter is to be defined by the manufacturer, but this specification defines the method of test to be used to determine the value of each specified parameter and the tolerance about which the parameter shall be controlled by the manufacturer.
1.3 The parameters to be defined in any GMT specification are defined in 4.1. Parameters to be specified are those, which should typically appear on data sheets. Only a selection of these parameters should be included on the certificate of conformity. The other parameters which are included in a specification should either be nominated by the manufacturer, or agreed between manufacturer and customer. These parameters are defined in 4.2.
1.4 A selection of the specified parameters should be used for quality control purposes to check the conformity. The specification defines which parameters should be used for checking the conformity of the material. These parameters are defined as part of 4.1. Other specified parameters may be included if critical for a particular application or processing method. This is to be agreed between manufacturer and customer of a production lot and will be reported in the certificate of conformity, which should be in accordance with EN 10204.
Verstärkte Thermoplast-Formmassen - Spezifikation für GMT - Teil 3: Besondere Anforderungen
Diese Europäische Norm ist eine Spezifikation für Flacherzeugnisse aus thermoplastischen Formmassen, die entsprechend der Beschreibung in Teil 1 dieser Spezifikation aus glasmattenverstärktem Polypropylen oder gleichwertigen Produkten bestehen.
In 4.1 werden die Parameter festgelegt, die in allen GMT Spezifikationen festgelegt werden müssen. Vorge-schrieben werden die Parameter, die üblicherweise auf Datenblättern anzugeben sind. In der Konformi-tätsbescheinigung sollte nur eine Auswahl dieser Parameter angegeben werden. Die anderen in einer Spezifikation angegebenen Parameter sollten entweder vom Hersteller benannt oder zwischen Hersteller und Kunde vereinbart werden. Diese Parameter werden in 4.2 festgelegt.
Zum Zwecke der Qualitätslenkung sollte für die Prüfung der Konformität eine Auswahl der vorgeschriebenen Parameter verwendet werden. Die Spezifikation legt fest, welche Parameter für die Prüfung der Konformität des Werkstoffs verwendet werden sollten. Diese Parameter werden als Teil von 4.1 festgelegt. Weitere vorge-schriebene Parameter dürfen einbezogen werden, falls sie für eine besondere Anwendung oder ein besonderes Verarbeitungsverfahren kritisch sind. Dies ist zwischen Hersteller und Kunde eines Produktionsloses zu verein-baren und in der Konformitätsbescheinigung nach EN 10204 anzugeben.
Préimprégnés renforcés thermoplastiques - Spécifications des GMT - Partie 3: Exigences particulières
1.1 Le présent document constitue la partie 3 de l'EN 13677. C'est une spécification pour les plaques thermoplastiques moulées par compression constituées de polypropylène renforcé de mat de verre textile ou constituées de produits équivalents, décrites dans la partie 1 de cette spécification.
Cette spécification définit les paramètres à spécifier ainsi que ceux qui s'avèrent nécessaires pour une application ou une méthode de traitement particulières.
1.2 Cette spécification ne définit aucune valeur absolue ou nominale pour les paramètres, celle-ci devant être définie par le fabricant. Cette spécification définit toutefois la méthode d'essai à utiliser pour déterminer la valeur de chaque paramètre spécifié et la tolérance à laquelle le paramètre doit être contrôlé par le fabricant.
1.3 Les paramètres à définir dans toute spécification relative au GMT sont donnés en 4.1. Les paramètres à spécifier sont ceux devant généralement apparaître sur les feuilles de suivi. Seule une sélection de ces paramètres doit figurer sur le certificat de conformité. Les autres paramètres compris dans une spécification doivent soit être désignés par le fabricant, soit faire l'objet d'un accord entre le fabricant et le client. Ces paramètres sont donnés en 4.2.
1.4 Une sélection des paramètres spécifiés doit être utilisée pour les besoins du contrôle qualité afin de vérifier la conformité d'un lot de production, et être notée sur le certificat de conformité du matériau, selon l'EN 10 204-3.1B. La spécification définit les paramètres à utiliser pour vérifier la conformité du matériau. Ces paramètres constituent une partie du 4.1. Les autres paramètres spécifiés peuvent y figurer si cela est essentiel pour une application ou une méthode de traitement particulières. Cette mention doit faire l'objet d'un accord entre le fabricant et le client.

Overview
EN 13677-3:2003 is the CEN specification for reinforced thermoplastic moulding compounds (GMT) - specifically textile glass‑mat reinforced polypropylene (or equivalent) in compression‑mouldable sheet form. As Part 3 of EN 13677, this document defines the specific requirements for GMT: which parameters must be specified, how those parameters are tested, and the tolerances manufacturers must control. The standard does not set absolute nominal values; instead it prescribes test methods and tolerance rules so manufacturers and customers can agree product data, certificates and quality control criteria.
Key topics and technical requirements
- Scope and purpose
- Applies to glass‑mat thermoplastic (GMT) compression moulding sheet based on polypropylene or equivalent matrices.
- Establishes which parameters should appear on data sheets and which may be optionally specified for particular applications or processing methods.
- Obligatory specified parameters (examples)
- Properties measured on GMT sheet as supplied: blank dimensions (thickness, length, width), blank weight, glass fibre content (EN ISO 1172), density (ISO 1183), melting/crystallisation temperatures (EN ISO 3146), processing shrinkage (ISO 2577).
- Properties measured on compression‑moulded test plaques: tensile strength, tensile modulus, tensile elongation (EN ISO 527‑4), impact strength (EN ISO 179‑2), puncture/energy absorption (EN ISO 6603‑2), heat deflection temperature (EN ISO 75‑2), thermal expansion (EN ISO 11403‑2).
- Tolerances and conformity checks: the standard prescribes individual and average tolerances for many parameters and identifies which should appear on a certificate of conformity.
- Optional parameters (examples)
- Flowability and processing stability, flexural/compressive properties (EN ISO 178, EN ISO 14126), shear and damping (EN ISO 6721‑2), water absorption (EN ISO 62), long‑term heat ageing, burning behaviour, electrical/ dielectric properties (IEC standards).
- Quality control & documentation
- Selection of specified parameters is used for lot conformity checks; conformity reporting should follow EN 10204 certificate formats.
Applications and users
- Typical users:
- GMT manufacturers and compounders defining product data sheets and production tolerances.
- OEMs (automotive, transport, consumer goods) specifying GMT materials for compression‑moulded parts.
- Quality engineers and testing laboratories implementing the prescribed test methods for acceptance and conformity.
- Procurement and compliance teams requiring certificate of conformity per EN 10204.
- Practical uses:
- Defining material acceptance criteria for structural interior and exterior components.
- Establishing test regimes and tolerances for process control and downstream moulding performance.
- Specifying material parameters relevant to mechanical, thermal and electrical performance of GMT parts.
