Reinforcements - Specification for textile glass rovings - Part 3: Specific requirements
This part of this European Standard gives a technical specification for rovings that are made from continuous filament textile glass. It defines those parameters which shall be specified plus other parameters which may be specified if required for a particular application or processing method.
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.
The parameters which shall always be defined in any roving specification are defined in clause 4.1 and 4.2. The other parameters which are included in a specification shall either be nominated by the manufacturer or agreed between manufacturer and customer. These parameters are defined in clause 4.3.

General Information
Overview
EN 14020-3:2002 is a European Standard developed by the European Committee for Standardization (CEN) that specifies the technical requirements for textile glass rovings used as reinforcements. This part of the EN 14020 series focuses on specific requirements for continuous filament textile glass rovings. The standard defines the mandatory and optional parameters to be specified, their testing methods, and tolerances, but it does not prescribe absolute or nominal values-these are set by the manufacturer based on application needs.
The standard is crucial for ensuring consistency, quality control, and interoperability in the manufacturing and application of textile glass rovings, which are critical components in composite materials used across various industries.
Key Topics
Scope and Purpose
It sets a framework for textile glass rovings specifications and defines which parameters must always be specified versus those optional for specific manufacturing or processing methods.Mandatory Parameters
Parameters that must always be defined in roving specifications include:- Loss on ignition (oxidizable residue content)
- Linear density (tex)
- Moisture content
The standard specifies test methods and tolerances for these parameters to maintain quality control over individual products and batches.
Optional Parameters
Depending on application or processing requirements, additional parameters can be specified, such as:- Tensile strength
- Acetone solubility
- Impregnated tensile strength
- Interlaminar shear strength (ILSS)
These support performance characteristics important in composite manufacturing methods like pultrusion, filament winding, or spray-up.
Design Parameters
Items like filament diameter and glass type are designated properties but are not subject to routine production quality control.Matrix Compatibility and Visual Properties
Matrix compatibility covers resin/polymer compatibility (epoxy, polyester, polypropylene, etc.), while visual properties include appearance acceptance criteria tailored to the intended application.Testing Methods
The standard references various ISO testing protocols (ISO 1887, ISO 3341, ISO 9163, ISO 14130, etc.) to determine the controlled parameters. It aligns test methods across manufacturers to assure reliability and comparability.
Applications
EN 14020-3:2002 supports a range of industrial processes and product designs involving textile glass rovings, including:
Composite Materials Manufacturing
Textile glass rovings serve as reinforcements in fiber-reinforced plastics (FRPs), improving mechanical strength and durability in automotive, aerospace, construction, marine, and sporting goods sectors.Pultrusion and Filament Winding
Specific tensile and impregnation strength parameters ensure rovings are optimized for these automated composite fabrication methods.Spray-Up and Sheet Molding Compound (SMC) Processes
Parameters like acetone solubility assist in selecting rovings suitable for particular resin systems and processing techniques.Quality Assurance and Product Specification
Manufacturers use this standard to define product properties and tolerances, facilitating clear communication and technical alignment with customers.
