Overview

EN 1624:1999 is a European Standard published by CEN that specifies a procedure to determine the flame spread of vertically oriented specimens of industrial and technical textiles. The test procedure is applied when specimens are tested in accordance with EN ISO 6941. The standard is intended to provide a reproducible method to evaluate burning behaviour (flame spread) of textile materials used in industrial and technical applications.

Key topics and requirements

• Scope: Applies specifically to industrial and technical textiles and textile products, with specimens mounted in a vertical orientation.
• Test focus: Measurement of flame spread along the vertically oriented specimen under the conditions defined in the referenced test method (EN ISO 6941).
• Reference method: Requires testing to be carried out in accordance with EN ISO 6941, ensuring consistency with the referenced international procedure.
• Classification context: Falls under ICS fields for textile fabrics (59.080.30) and ignitability / burning behaviour (13.220.40).
• Reproducibility and compliance: The standard establishes a uniform approach so results are comparable between laboratories and across product evaluations.
• Note: This summary does not reproduce procedural specifics from the standard text; users should consult EN 1624:1999 and EN ISO 6941 for full test setup, instrumentation, and reporting requirements.

Applications

EN 1624:1999 is practical for organizations needing to assess or control burning behaviour of textiles used in non-consumer technical contexts:

• Textile and component manufacturers evaluating material performance during product development and quality control.
• Independent test laboratories performing standardized flammability testing and issuing test reports.
• Safety and compliance officers assessing material suitability for industrial installations, filtration, geotextiles, conveyor belts, and other technical textile applications.
• Specifiers and procurement teams selecting materials that meet safety or contractual performance requirements.
• Risk assessors and insurers using standardized test data to evaluate fire-related hazards.

Who should use this standard

• Manufacturers of industrial and technical textiles
• Accredited testing laboratories
• Product designers and engineers in industrial sectors
• Regulatory bodies and certifiers concerned with material fire performance

Related standards

• EN ISO 6941 - referenced test method for burning behaviour of vertically oriented specimens (required for applying EN 1624:1999).
• Users should consult both EN 1624:1999 and the referenced EN ISO 6941 text for complete procedural and reporting details.
