ISO 5025:2017

Overview

ISO 5025:2017 is an internationally recognized standard that specifies the method for determining the width and length of woven-fabric reinforcement products presented in roll form. Published by the International Organization for Standardization (ISO), this standard provides precise guidelines for measuring these critical dimensions in reinforcement fabrics used across various industries. The method ensures accuracy, repeatability, and consistency essential for quality control, product specification, and compliance in manufacturing and supply chains.

Key Topics

• Measurement Scope: Applies specifically to woven-fabric reinforcements in roll form, focusing on the accurate determination of fabric width and length.
• Width Definition: Width is measured as the distance perpendicular to the warp yarns, between the outermost warp yarn edges.
• Measurement Tools: Requires calibrated rulers or measuring devices with strict permitted error margins (not exceeding 0.1 cm for fabrics up to 150 cm wide and 0.15% for wider fabrics).
• Length Measurement: Uses measurement equipment capable of assessing roll length with a maximum permissible error of 1%, including devices like drum counters or counting systems calibrated for tension during fabric measurement.
• Testing Procedure:
  • Width is determined by averaging two measurements at least 100 cm apart on the fabric roll.
  • Length is measured directly via meters or fractions of meters to maintain 1% accuracy.
• Sampling and Specimen: The test specimen typically includes one full fabric roll. Sampling sizes may be adapted according to product specifications or buyer requirements.
• Result Expression: Width is expressed in centimeters to the nearest 0.1 cm; length is recorded in meters or fractions thereof.
• Report Requirements: Test reports must reference ISO 5025:2017, give detailed fabric descriptions, dimensions measured, and note any unusual conditions affecting results.

Applications

ISO 5025:2017 plays a vital role in industries utilizing woven fabric reinforcements, such as:

• Composite Materials Manufacturing: Ensuring accurate fabric dimensions for optimal reinforcement in composite parts.
• Textile and Technical Fabrics: Quality control of industrial textiles to match precise customer or engineering specifications.
• Construction and Civil Engineering: Verification of geotextile fabric sizes for infrastructure applications.
• Automotive and Aerospace: Compliance checking for fabric reinforcements used in high-performance structural components.
• Roll Goods Inspection: Standardized measurement method enabling efficient inspection, inventory management, and logistics of fabric rolls.

By adopting ISO 5025:2017, companies can reduce discrepancies in fabric sizing, streamline quality assurance workflows, and enhance communication between suppliers and customers.

Related Standards

• ISO 22198 – Textiles: Provides related measurement methods for fabric width and length, specifically covering textile fabrics beyond reinforcement products.
• ISO 2859-1 – Sampling Procedures for Inspection by Attributes: Offers sampling guidance that complements the testing sampling approach in ISO 5025.
• ISO 3951-1 – Sampling Procedures for Inspection by Variables: Defines variable inspection sampling plans, useful for fabric roll quality acceptance.

Using ISO 5025:2017 in conjunction with these standards supports comprehensive quality and conformity assessments for woven fabric reinforcements and textiles.

Implementing ISO 5025:2017 ensures precise, reproducible measurements of woven fabric reinforcement dimensions, critical for manufacturing excellence and reliable product performance in diverse industrial sectors.
