Overview

prEN ISO 9405:2026 (Textile floor coverings - Assessment of changes in appearance) provides standardized procedures to evaluate changes in the visual appearance of textile floor coverings after mechanical stress. Developed by CEN and ISO (TC 219), this standard is applicable to all types of textile floor coverings and guides the assessment process using standardized reference scales and illumination conditions. The assessment methods are built around testing protocols such as the Vettermann drum, hexapod tumbler, and castor chair tests, ensuring consistent, objective, and repeatable results.

Assessment in accordance with ISO 9405 is crucial for manufacturers, testing laboratories, and users who require a reliable basis for evaluating the durability and visual quality of textile flooring after simulated foot traffic and mechanical wear.

Key Topics

  • Change in Appearance: Defines and categorizes physical and visual changes in textile floor coverings, including colour variation, loss of pile definition, crushing, felting, hairiness, pilling, and pattern definition changes.
  • Standardized Procedures: Details the specimen selection, preparation, conditioning, and assessment methods to ensure consistent evaluation.
  • Use of Reference Scales: Instructs the use of digital image reference scales and large grey scales for visually grading changes from grade 5 (no change) to grade 1 (extreme change).
  • Assessment Conditions: Specifies the viewing environment-including lighting (D65 light source, 600 lux minimum), viewing cabinet dimensions, and assessment distances-to guarantee reproducibility.
  • Qualified Assessors: Requires evaluations to be performed independently by at least three trained assessors, with the process extended if discrepancies in grading are significant.
  • Reporting Requirements: Outlines necessary details for test reporting, including sample identification, reference scales used, individual and median grading, dominant change factors, and deviations.

Applications

  • Product Development & Quality Control: Floor covering manufacturers use ISO 9405 to assess product durability, inform improvements, and validate product performance claims.
  • Comparative Testing: Laboratories apply this standard to perform comparative evaluations of different textile floor coverings and verify compliance with durability requirements.
  • Specification & Procurement: Buyers and specifiers refer to the results obtained from ISO 9405 testing when selecting suitable textile floor coverings for high-traffic or demanding applications.
  • Regulatory Compliance: Adhering to ISO 9405 ensures alignment with national and international regulations and guidelines for flooring performance and safety.
  • Research & Certification: Certification bodies use this standard as a benchmark for granting eco-labels, quality marks, or other conformance certifications both in Europe and internationally.

Related Standards

  • ISO 10361 / ISO 23106 / EN 18320: Procedures for producing changes in appearance using the Vettermann drum tester.
  • ISO 23122: Procedures for producing changes in appearance using a hexapod tumbler tester.
  • ISO 4918: Resilient, textile, and laminate floor coverings - Castor chair test, a method for simulating wear under rolling chair use.
  • ISO 105-A01 and ISO 105-A02: Standard methods for colour fastness testing and grey scale grading.
  • EN 1471: Textile floor coverings - Assessment of changes in appearance (complementary guidance).
  • ISO 2424: Vocabulary for textile floor coverings, providing uniform terminology.

Practical Value

Applying prEN ISO 9405 helps organizations ensure their textile floor coverings perform as expected under real-world conditions, supporting reliable durability statements, achieving customer satisfaction, and facilitating successful market access. By following objective assessment methods and comparability across different products and laboratories, stakeholders across the floor covering supply chain can make informed choices grounded in internationally recognized standards for appearance retention.
