Plastics — Glass-fibre-reinforced products — Determination of fibre length

This document specifies a method of determining the length of the fibres present in a fibre-reinforced product. The method is applicable to moulding materials and to moulded parts. The test conditions specified limit the application of this method to thermoplastics reinforced with short glass fibres (less than 1 mm long), i.e. fibres whose length is less than or equal to 7,5 mm prior to incorporation in the moulding material and moulding.

Plastiques — Produits renforcés de fibres de verre — Détermination de la longueur des fibres

L'ISO 22314:2006 spécifie une méthode permettant de déterminer la longueur des fibres présentes dans un produit renforcé de fibres de verre. La méthode est applicable aux matières à mouler et aux pièces moulées. Les conditions d'essai spécifiées limitent l'application de cette méthode aux thermoplastiques renforcés de fibres de verre courtes (longueur inférieure à 1 mm), dont la longueur, avant l'incorporation dans la matière à mouler et le moulage, est inférieure ou égale à 7,5 mm.

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.
