Overview

ISO 1268-4:2005/Amd 1:2010 is an important amendment to the international standard that defines methods for producing test plates from fibre-reinforced plastics (FRP), specifically focusing on the moulding of prepregs. Developed by ISO Technical Committee ISO/TC 61, Subcommittee SC 13, this amendment provides updated procedural details and clarifications to ensure consistent and reliable production of composite test plates critical for material characterization.

This standard addresses the technical process of moulding prepregs-pre-impregnated fibres ready for curing-into test specimens for evaluating fibre-reinforced plastic performance. It also references related standards for determination of fibre, resin, and void contents, which are essential parameters defining composite quality.

Key Topics

  • Moulding Process of Prepregs: Detailed guidelines for assembling and press-moulding prepreg layers into test plates, including specified temperature, humidity conditioning, and vacuum requirements.
  • Reference Updates: Removal of ISO 291 and inclusion of ISO 14127, which standardizes testing for resin, fibre, and void content in carbon-fibre-reinforced composites.
  • Vacuum Specifications: Correction of vacuum pressure requirement to 0.008 MPa or better, ensuring proper consolidation during moulding.
  • Test Plate Assembly: Addition of a typical assembly diagram for press moulding, with components such as cover plates, base plates, spacers, absorbent materials, metal edge strips, and pressure blankets defined.
  • Material Conditioning: Conditioning prepregs at (23 ± 2) °C and (50 ± 5) % relative humidity for at least 2 hours before moulding to maintain consistent material properties.
  • Fibre and Void Content Measurement: Instructions to apply ISO 1172 for glass fibre or inert fibres and ISO 14127 for carbon fibre composites; void content to be measured according to ISO 7822 or ISO 14127.

Applications

This standard amendment is essential for manufacturers, quality control laboratories, and research institutions involved with fibre-reinforced plastics. Its practical value includes:

  • Quality Assurance in FRP Production: Ensures test plates used for mechanical and physical evaluation are produced under controlled, repeatable conditions.
  • Composite Material Development: Facilitates standardized production of test specimens crucial for developing new prepreg materials with optimized fibre-matrix ratios and void minimization.
  • Certification and Compliance Testing: Supports compliance with international testing protocols for composite materials used in aerospace, automotive, sports, and construction industries.
  • Research and Testing Consistency: Provides a harmonized methodology allowing reliable comparisons of composite performance data across laboratories globally.

Related Standards

  • ISO 14127: Carbon-fibre-reinforced composites - Determination of the resin, fibre, and void contents, complementing Part 4 of ISO 1268 by specifying content measurement techniques.
  • ISO 1172: Plastics - Reinforcement fibres - Determination of density by gas pycnometer method, applicable for fibre content in glass and other inert fibres.
  • ISO 7822: Plastics - Methods of determining the apparent void content in reinforced plastic parts using microscopic image analysis.
  • ISO 1268 Series: Other parts of the ISO 1268 family cover different methods for producing test plates from various types of fibre-reinforced plastics.

By following ISO 1268-4:2005/Amd 1:2010 and its referenced standards, stakeholders ensure accurate, reproducible production of FRP test specimens, enabling high-confidence evaluation of composite materials critical for structural integrity and performance optimization.

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 International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée
aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du
comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur
