ISO 18270:2026

Overview

ISO 18270:2026 provides comprehensive classification and performance guidelines for leather upholstered products. Developed by the International Organization for Standardization (ISO), this standard applies to all types of products using leather as the main upholstery material, ranging from furniture and decorative items to products for babies and everyday consumer goods. The guidelines address both semi-finished and fully finished leather upholstery materials, ensuring consistency across all levels of production and usage.

Implementing ISO 18270:2026 helps manufacturers, suppliers, and consumers benefit from standardized leather quality, reliability, and product labelling, supporting informed choices and increased product safety.

Key Topics

• Product Classification: The standard distinguishes leather upholstered products into four main product classes, based on their intended use and contact with the human body:

  • Class I: Products for babies and small children (up to 36 months).
  • Class II: Products with direct skin contact (e.g., chairs, beds).
  • Class III: Products without direct skin contact or with minimal, occasional contact (e.g., wall coverings, cabinets).
  • Class IV: Decorative products with no regular direct skin contact.

• Performance Guidelines: ISO 18270:2026 sets forth recommended performance characteristics for leather upholstery, including:

  • Mechanical durability (e.g., tear load, flex resistance)
  • Color fastness (resistance to rubbing, perspiration, and light)
  • Safety (such as burning behavior and cold crack resistance)
  • pH specification and finish adhesion for appropriate classes

• Testing and Sampling: The guidelines recommend preparation and testing of either finished products or their component materials to verify compliance with performance requirements.

• Marking and Labelling: Proper product labelling is required, including manufacturer information, product class, reference to ISO 18270:2026, care instructions, and precise designation of the materials used (e.g., "leather," "part leather").

• Terminology: Clear definitions of key terms such as "upholstered product," "contact area," and "product class" ensure consistency and understanding throughout the industry.

Applications

ISO 18270:2026 is valuable across various industries and scenarios, including:

• Furniture Manufacturing: Assists manufacturers in designing, producing, and certifying leather sofas, chairs, beds, and other seating in compliance with international standards for safety and quality.
• Children’s Products: Ensures that leather products intended for babies and small children adhere to rigorous safety and performance criteria.
• Interior Design and Decor: Supports the creation and labelling of decorative leather goods for both commercial and residential spaces.
• Retail and E-commerce: Provides clear guidelines for accurate product description, fair marketing, and customer transparency.
• Quality Assurance: Offers a benchmark for regulatory bodies, testing laboratories, and quality control departments in assessing leather upholstered products.

By implementing ISO 18270:2026, organizations can enhance product reputation, promote consumer safety, and gain access to new international markets by demonstrating compliance with recognized classification and performance guidelines for leather upholstered products.
