Full title and description

ISO 10548:2002 — Carbon fibre — Determination of size content. This International Standard specifies laboratory test methods to determine the amount (content) of sizing/size on carbon-fibre yarns.

Abstract

ISO 10548:2002 defines procedures for measuring the size (ensimage, sizing) content of carbon-fibre yarns, and is applicable to both continuous-filament yarns and staple-fibre yarns. The standard provides the principle, specimen preparation, conditioning and one or more test methods (including solvent extraction).

General information

• Status: Published (international standard; confirmed in ISO systematic review).
• Publication date: July 2002 (2002-07).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 59.100.20 (Carbon materials / carbon fibres).
• Edition / version: Edition 2 (second edition, 2002).
• Number of pages: 8.

Scope

Specifies test methods for the determination of the size (sizing) content of carbon-fibre yarns. The scope covers sampling and specimen preparation, conditioning, and detailed test procedures for determining size content in continuous-filament and staple-fibre carbon yarns. The standard is intended for use where quantification of sizing is required for quality control, incoming inspection or materials characterization.

Key topics and requirements

• Definition of terms and units related to size (sizing) content.
• Requirements for test specimens and conditioning prior to analysis.
• Primary test methods, including solvent-extraction technique(s) to remove and quantify sizing (Method A: solvent extraction noted in the standard).
• Calculation and reporting of size content as a percentage of yarn mass.
• Notes on repeatability, limitations and applicable yarn types (continuous filament and staple fibre).

Typical use and users

Used by laboratories, quality-control engineers, composite materials manufacturers, carbon-fibre yarn producers, incoming inspection teams and R&D groups needing an objective, repeatable measurement of sizing on carbon fibre yarns for process control, product specification or comparative testing.

Related standards

Supersedes ISO 10548:1994 (first edition) and has an associated Technical Corrigendum ISO 10548:2002/Cor 1:2008. Regional/adopted equivalents include EN ISO 10548 (published as EN ISO 10548:2003 / 2004 editions) and identical national adoptions (for example GOST R ISO 10548:2012).
