Resilient and textile floor coverings - Determination of length, width and straightness of sheet (ISO 24341:2006)

ISO 24341:2005 specifies methods for determining the length, width and straightness of resilient or textile floor coverings in sheet form.

Elastische und textile Bodenbeläge - Bestimmung der Länge, Breite und Geradheit einer Bahn (ISO 24341:2006)

Diese Internationale Norm legt ein Verfahren zur Bestimmung der Länge, Breite und Geradheit von elastischen Bodenbelägen in Bahnenform fest. Die Geradheit elastischer oder textiler Bodenbeläge ist ein wichtiger Faktor, denn der verlegte Bodenbelag hat ein unzulässiges Erscheinungsbild, wenn die Kanten der Fertigungsrichtung des Bodenbelages in Bahnen-form übermäßig von einer geraden Linie abweichen.

Revêtements de sol résilients et textiles - Détermination de la longueur, de la largeur et de la rectitude des lés (ISO 24341:2006)

L'ISO 24341:2005 spécifie des méthodes de détermination de la longueur, de la largeur et de la rectitude des revêtements de sol résilients ou textiles sous forme de lés.

Netekstilne in tekstilne talne obloge - Ugotavljanje dolžine, širine in ravnosti robov (ISO 24341:2006)

Ta mednarodni standard določa metode za ugotavljanje dolžine, širine in ravnosti robov netekstilnih ali tekstilnih talnih oblog v obliki trakov. Ravnost robov netekstilnih ali tekstilnih talnih oblog je pomembna, saj nameščene talne obloge ne bodo lepega videza, če so robovi traku v vzdolžni smeri zelo neravni.

Overview

EN ISO 24341:2012 is a European adoption of the international standard ISO 24341:2006, specifying standardized methods for the determination of length, width, and straightness of resilient and textile floor coverings in sheet form. Developed by ISO Technical Committee ISO/TC 219 and adopted by CEN Technical Committee CEN/TC 134, this standard replaces the earlier EN 426:1993 and provides clear, consistent procedures ensuring reliable dimensional quality control of flooring sheets.

Accurate measurement of length, width, and straightness is crucial because deviations can affect the aesthetic appearance, fit, and installation performance of sheet flooring products. This standard applies universally to rolls and sheets of resilient (non-textile) and textile floor coverings and is widely implemented by manufacturers, testing laboratories, and quality assurance professionals throughout Europe and globally.

Key Topics

• Scope: Defines precise, repeatable methods to measure the length, width, and straightness of resilient and textile sheets.
• Measurement Principles:
  • Length is measured along the sheet’s longitudinal axis.
  • Width is measured at multiple points along the length.
  • Straightness is assessed by comparing edges to a virtual straight line using a string line.
• Apparatus Required:
  • Ruler or semi-rigid tape for width measurement (accuracy to 0.05%).
  • Calibrated measuring device for length (accuracy to 0.1%).
  • Flat surface/table larger than the test piece.
  • String line (10 m) for straightness testing.
• Test Conditions: Specimens must be conditioned at ambient laboratory temperature for at least 4 hours prior to testing.
• Sampling Guidelines:
  • For width and length, the entire roll must be used whenever possible.
  • For straightness, a minimum test piece length of 5 meters is required.
• Calculation & Reporting:
  • Width is expressed as the smallest of three measurements rounded to 5 mm.
  • Length is the average of two measurements rounded to nearest 0.05 m.
  • Straightness deviation is reported as the greatest edge deviation measured.
• Test Report Requirements: Include details such as product identification, test environment, measurement results, any deviations from the standard, and precision information.

Applications

EN ISO 24341:2012 is essential for manufacturers and quality controllers of resilient and textile sheet floor coverings to:

• Ensure consistency and conformance to dimensional specifications before market release.
• Verify that sheet flooring products will fit correctly during installation without edge distortion.
• Maintain high quality and appearance standards by detecting manufacturing irregularities such as width variations or edge waviness.
• Provide standardized, repeatable test results usable for certification, quality audits, and regulatory compliance.
• Facilitate international trade with harmonized testing procedures, enabling cross-border acceptance of flooring products.

This standard is widely used in production facilities, flooring testing laboratories, construction quality assurance, and flooring specification documents to assure durable, well-fitting, and visually appealing sheet floor coverings.

Related Standards

For additional context and complementary testing methods related to floor coverings, consider the following standards:

• EN 426:1993 – Former European standard for resilient floor coverings which ISO 24341 supersedes.
• JIS A 1454 – Japanese Industrial Standard outlining test methods for resilient floor coverings, including dimensional checks.
• ISO/TC 219 series – Broader technical committee standards covering various aspects of floor covering products and testing.
• ISO/IEC Directives – Framework guiding preparation and adoption of international standards, ensuring quality and consistency.

Utilizing EN ISO 24341:2012 alongside related standards promotes comprehensive quality management for resilient and textile flooring products across manufacturing, testing, and installation sectors.
