BS ISO 2797-2017 PDF

Full title and description

STB BS ISO 2797-2017 — Textile glass — Rovings — Basis for a specification. This document is the 2017 (third) edition of ISO 2797, published as an international standard that establishes the basis for specifying textile glass rovings (direct and assembled rovings), including required designations, sampling, conditioning, properties and delivery, packaging and labelling requirements.

Abstract

ISO 2797:2017 defines the information and test-property framework to be used when preparing product specifications for textile-glass rovings. It sets out terminology, designation format, sampling and batch-acceptance procedures, conditioning, a list of properties and test methods (filament diameter, linear density, moisture, size and size content, catenary, stiffness, abrasion resistance, strand integrity, mechanical and visual properties), and requirements for winding, packaging, labelling and storage. The aim is consistent, reproducible specifications that enable manufacturers, converters and end-users to select and verify rovings for composite processes.

Scope

This standard provides the basis for a product specification for textile glass rovings intended for use in reinforced plastics and composite manufacture. It covers designation and terminology, sampling and batch acceptance, conditioning prior to test, the properties and test methods to be specified (physical, mechanical and visual), and the recommended practices for winding, packaging, labelling and storage of rovings intended for further processing (winding, weaving, pultrusion, chopping/spray-up, SMC, etc.). It does not prescribe detailed process parameters for downstream manufacturing but defines the material characteristics and acceptance criteria to be referenced in commercial specifications.

Key topics and requirements

• Designation and terminology for textile-glass rovings (how to describe direct and assembled rovings).
• Sampling plans and batch-acceptance criteria to ensure representative testing and quality control.
• Conditioning procedures prior to testing to ensure comparable test conditions.
• List of properties and associated test methods: filament diameter, linear density (tex/dtex), moisture content, size and size content, catenary, stiffness, abrasion resistance, strand integrity, key mechanical properties and visual assessments.
• Requirements and recommendations for winding, packaging, labelling and storage to maintain product integrity in transit and storage.
• Guidance for inclusion of these items in commercial product specifications between supplier and purchaser.

Typical use and users

Used by manufacturers of textile-glass rovings and sizings, converters and suppliers of reinforcement materials, composite fabricators (winding, weaving, pultrusion, spray-up, SMC/hand-layup), quality and procurement engineers setting acceptance criteria, test laboratories performing verification, and standards committees referencing harmonized roving requirements for product specifications and procurement contracts. It is especially relevant where consistent filament and sizing characteristics are required for process compatibility and predictable composite performance.

Related standards

Standards that are commonly referenced alongside ISO 2797 include other ISO documents on glass-fibre and filament properties, sampling and test methods (for example ISO standards for glass-fibre linear density and related test methods) and standards governing composite testing and quality systems. Typical cross-references appearing in bibliographies and related lists include ISO 2078, ISO 1888, ISO 1889, ISO 1887 and other ISO test-method standards relevant to textile glass and composite reinforcement materials.

FAQ

Q: What is this standard?

A: ISO 2797:2017 (also published as BS ISO 2797:2017 in the UK) is an international standard that establishes the basis for specifying textile-glass rovings — describing what information and test properties should be included in a product specification for rovings.

Q: What does it cover?

A: It covers designation and terminology, sampling and batch-acceptance, conditioning before testing, a defined set of properties and associated test-method references (filament diameter, linear density, moisture, size/size content, catenary, stiffness, abrasion resistance, strand integrity, mechanical and visual properties), and delivery requirements such as winding, packaging, labelling and storage.

Q: Who typically uses it?

A: Roving manufacturers and suppliers, composite fabricators and converters, procurement and quality engineers, test laboratories and standards/technical committees preparing product specifications or procurement contracts for textile-glass rovings.

Q: Is it current or superseded?

A: ISO 2797:2017 is the current (third) edition published in 2017 and it replaced ISO 2797:1986. ISO lists the 2017 edition as published/confirmed; users should check national adoption notices (for example BS adoption dates) for technical deliverables and confirm whether any amendments or later revisions have been issued by ISO or national bodies.

Q: Is it part of a series?

A: It is a standalone product-specification basis for textile-glass rovings but is commonly used alongside other ISO standards addressing glass-fibre materials, sampling and test methods and composite testing; therefore it functions as part of a broader family of standards for textile glass and composites.

Q: What are the key keywords?

A: textile glass, rovings, specification, filament diameter, linear density, size content, sampling, conditioning, packaging, labelling.
