Overview

The oSIST prEN 16662-2:2023 standard, developed by CEN Technical Committee CEN/TC 301, specifies specific test procedures for supplementary grip devices (SGDs) designed for tyres of passenger cars and light-duty vehicles. These SGDs enhance tyre traction in challenging driving conditions such as snow or ice. This part 2 document focuses on testing metallic, textile fabric, non-metallic net, and hybrid SGDs to ensure safety, durability, and reliability.

Key Topics

• Scope and Categories
  • Metallic SGDs
  • Textile fabric SGDs
  • Non-metallic net SGDs
  • Hybrid SGDs (combination of above types)
• Test Procedures
  • Corrosion protection: Evaluation includes electro-galvanizing specifications to prevent metal part degradation.
  • Strength testing: Tensile forces are applied to components, simulating real-world stresses (e.g., 4000 N for metallic parts).
  • Wear durability: Hardness tests (ISO 6507-1) and abrasion resistance (Martindale and Frank/Hauser tests) examine material endurance.
  • Tread surface strength: Measured longitudinally and laterally, ensuring grip materials resist deformation and failure under load.
• Test Methodologies
  • Use of standard textile tensile tests (EN ISO 13934-1) for fabrics and non-metallic nets.
  • Martindale abrasion test (EN ISO 12947) for assessing wear performance.
  • Customized tensile and wear setups for various SGD tread designs.
• Hybrid SGDs
  • Must pass full tests of one category (metallic, textile fabric, or non-metallic net) to achieve certification.
  • If hybrid SGDs fail tests in all categories, they are currently non-certifiable under this standard.

Applications

oSIST prEN 16662-2:2023 is critical for manufacturers, testing laboratories, and certification bodies involved in producing and approving supplementary grip devices. Its practical value includes:

• Ensuring consistent quality and safety of SGDs entering the European market.
• Providing clear testing benchmarks for grip device durability under realistic environmental and operational stress.
• Enhancing driver safety by certifying devices that maintain grip performance on challenging road surfaces.
• Supporting innovation in SGD materials by defining standardized procedures for textile, metallic, and hybrid grip solutions.
• Assisting regulatory compliance in member states by harmonizing test requirements across Europe.

Related Standards

• EN 16662-1:2020 – General safety and performance requirements for supplementary grip devices.
• EN ISO 13934-1 – Determination of tensile strength and elongation in textiles via the strip method.
• EN ISO 12947 series – Martindale abrasion resistance testing of fabrics.
• ISO 6507-1 – Vickers hardness test method for metallic materials.
• DIN 53863 series – Textile abrasion test methods.

Understanding and applying oSIST prEN 16662-2:2023 enables manufacturers and testers to deliver reliable SGDs, improving road safety and vehicle performance under winter driving conditions. This standard complements general safety requirements by providing detailed and type-specific test procedures crucial for product certification and market acceptance.
