EN ISO 6940:2026 PDF

Overview

EN ISO 6940:2026 specifies a standardized test method for assessing the burning behaviour and ease of ignition of textile fabrics, particularly when these are vertically oriented. As developed by CEN in alignment with ISO 6940:2026, this standard applies to a broad scope of textile products, including single and multi-component fabrics, as well as coated, quilted, multilayer, and sandwich constructions. By exposing textile specimens to a small, defined flame under controlled laboratory conditions, this method quantifies how easily fabrics ignite, supporting regulatory compliance and fire safety management across various industries.

Key Topics

• Ignitability Assessment: The standard outlines procedures for determining the ease of ignition for vertically oriented textile specimens, detailing both “surface ignition” and “bottom edge ignition” test methods.
• Specimen Preparation and Mounting:
  • Detailed guidance on sample sizing, orientation, and preparation ensures reproducibility.
  • Instructions for mounting specimens and handling visually or structurally diverse fabrics.
• Conditioning and Test Atmosphere:
  • Conditioning protocols for temperature and humidity to ensure accuracy.
  • Requirements for test environments, including air movement and ventilation for operator safety.
• Test Apparatus:
  • Specifications for burners, specimen holders, and timing devices.
  • Procedures for burner adjustment and positioning to maintain consistent flame exposure.
• Result Calculation and Reporting:
  • Calculation of mean ignition time, covering both ignition and non-ignition instances.
  • Guidance on reporting, including all relevant parameters and deviations for comprehensive documentation.
• Health and Safety Measures:
  • Recommendations on safe handling, fume extraction, and minimizing risks during testing.

Applications

Adherence to EN ISO 6940:2026 is critical for manufacturers, testing laboratories, and regulatory bodies involved with textile materials. Key application areas include:

• Product Compliance: Verifying fire behaviour of textiles used in clothing, furnishings, automotive interiors, and industrial products for compliance with fire safety regulations.
• Quality Assurance: Supporting consistent production of flame-resistant textiles through standardized testing protocols.
• Research and Development: Facilitating comparative studies and innovations in flame-retardant textile technologies.
• Regulatory Approval: Providing essential data for product certifications and for meeting legal safety requirements across international markets.
• Risk Assessment: Evaluating the fire risk profile of new materials, assemblies, and end products used in commercial, public, or residential environments.

Related Standards

Organizations and professionals referencing EN ISO 6940:2026 should also consider the following related standards to achieve comprehensive fire safety and textile performance assessments:

• ISO 6941 - Textile fabrics: Burning behaviour - Measurement of flame spread properties of vertically oriented specimens.
• ISO 4880 - Burning behaviour of textiles and textile products – Vocabulary (key for terminology used in EN ISO 6940).
• ISO 15025 - Protective clothing: Protection against heat and flame - Method for limited flame spread.
• ISO 9239-1 - Reaction to fire tests for floorings: Determination of the burning behaviour using a radiant heat source.

Incorporating EN ISO 6940:2026 into product development and testing protocols promotes International best practices for flame resistance, ignitability assessment, and fire safety compliance across the textile industry.
