Plastics - Phenolic resins - Determination of reactivity on a B-transformation test plate (ISO 8987:2005)

This International Standard specifies methods for the determination of the B-transformation time of phenolic resins at a specified temperature and under specified conditions on a heated test plate. Two methods are described, each with a different test plate: Method A - plate with depressions in the form of segments of spheres; Method B - flat plate without depressions.

Kunststoffe - Phenolharze - Bestimmung der Reaktivität auf einer B-Zeit-Prüfplatte (ISO 8987:2005)

Diese Internationale Norm legt Verfahren für die Bestimmung der B-Zeit von Phenolharzen bei festgelegter Temperatur unter festgelegten Bedingungen auf einer beheizten Prüfplatte fest. Zwei Verfahren werden beschrieben, jedes mit einer anderen Prüfplatte:
Verfahren A: Prüfplatte mit Vertiefungen in der Form von Kugelsegmenten;
Verfahren B: flache Prüfplatte ohne Vertiefungen.

Plastiques - Résines phénoliques - Méthodes d'évaluation de la réactivité sur plaque d'essai de transformation au stade B (ISO 8987:2005)

L'ISO 8987:2005 spécifie des méthodes de détermination du temps de transformation au stade B des résines phénoliques, à une température et dans des conditions spécifiées, sur plaque d'essai chauffée.
Deux méthodes sont décrites, chaque méthode étant spécifique à un type de plaque:
Méthode A: plaque avec des empreintes en forme de segment de sphères;
Méthode B: plaque plate sans dépressions.

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 Intern
