ISO 8516:2011

Overview

ISO 8516:2011 is an international standard that establishes the basis for specifications for textured yarns made from textile glass. Textured glass yarns, produced from single or folded yarns, are created through various processes that give the yarn a bulky, textured appearance. This standard defines key characteristics, testing methods, and quality criteria essential for manufacturers, suppliers, and users in industries utilizing textile glass textured yarns. Applications include insulation, filtration, decorative textiles, reinforcement of plastics, and packaging materials, making ISO 8516:2011 crucial for quality assurance and specification development in these sectors.

Key Topics

• Scope of Application: Defines textured yarns from single or multiple glass strands with a "bulky" texture, specifying the processes and materials used.
• Designation: Yarn identification must comply with ISO 2078 for consistent naming conventions.
• Physical Properties: Detailed requirements cover:
  • Type of glass used in the yarn (referencing ISO 2078).
  • Size content for lubrication during texturizing, measurable via ISO 1887.
  • Average filament diameter (ISO 1888).
  • Linear density of the yarn, determined per ISO 1889.
  • Moisture content assessed using ISO 3344.
  • Breaking load and yield strength tested according to ISO 3341.
• Visual Quality and Defects: Specification includes acceptable visual criteria and defect classifications of yarn and packages, such as:
  • Dirty or damaged yarn.
  • Incorrect number or mixed yarns.
  • Incomplete texturization.
  • Package issues like hardness, trapped foreign matter, or incorrect identification.
• Delivery Requirements: Packaging and labelling must feature essential information such as yarn designation, package type, net mass, supplier name, and manufacturing date.
• Storage Conditions: Recommendations for temperature, humidity, and duration to maintain yarn property integrity over time.

Applications

ISO 8516:2011 textured glass yarns are widely applied in industries including:

• Thermal Insulation: Due to glass yarn’s heat-resistant and lightweight attributes, providing enhanced performance in construction materials.
• Filtration Systems: Textured yarn structure improves filtration efficiency across various industrial and environmental applications.
• Decorative Textiles: Offers aesthetic and functional benefits in fabric manufacturing for upholstery and artistic textiles.
• Plastic Reinforcement: Enhances mechanical strength and durability of composite plastics in automotive, aerospace, and consumer goods.
• Packing Materials: Used for strength and protection in packaging solutions for fragile and heavy goods.

By adhering to ISO 8516:2011, manufacturers and users ensure product consistency, meet safety and performance standards, and facilitate global trade and quality control.

Related Standards

ISO 8516:2011 refers to and complements several other key standards essential for textile glass yarn specification and testing:

• ISO 2078 – Textile glass yarn designation.
• ISO 1887 – Determination of combustible matter content in textile glass.
• ISO 1888 – Measurement of average filament diameter for textile glass staple fibers.
• ISO 1889 – Determination of linear density of reinforcement yarns.
• ISO 3341 – Testing breaking force and elongation of textile glass yarns.
• ISO 3344 – Measuring moisture content in reinforcement products.
• ISO 472 – Plastics vocabulary providing relevant definitions for terms used.

Compliance with ISO 8516:2011 alongside these standards supports comprehensive quality control across all stages of textured glass yarn production, testing, delivery, and usage.
