ISO 22198:2006

Overview

ISO 22198:2006 - Textiles - Fabrics - Determination of Width and Length establishes a standardized method for accurately determining the length and width of textile fabrics in a tension-free, relaxed state. This international standard by ISO is designed for use with textile fabrics of full width, those folded lengthwise, or tubular constructions, with samples no longer than 100 meters. ISO 22198:2006 does not apply to coated fabrics and does not address the assessment of construction or other defects. Reliable measurements ensure quality control and consistency throughout the textile industry supply chain.

Key Topics

• Standardized Measurement Method:
  ISO 22198:2006 defines a uniform approach to measuring the length and width of textiles under relaxed, tension-free conditions, improving data consistency and comparability.

• Sample Conditions:
  Measurements must be carried out after conditioning fabrics in a standard atmosphere, ensuring results reflect the relaxed state of the material.

• Applicable Fabric Forms:
  The standard applies to textiles in full width, folded, or tubular form, provided the total piece length does not exceed 100 meters.

• Exclusions:
  The method is not suitable for coated fabrics, nor does it address fabric defects or construction irregularities.

• Measurement Tools and Protocols:

  • Calibrated rules conforming to measurement equipment quality standards
  • Flat measuring surfaces with sufficient length and width
  • Specific requirements for the number and distribution of width measurements based on the total length of the sample

• Reporting Requirements:
  Comprehensive test reports must include sample identification, configuration, measurement results (mean values, confidence limits, coefficient of variation), and any deviations from the specified procedure.

Applications

Adherence to ISO 22198:2006 supports a variety of crucial functions across the textile sector:

• Quality Assurance and Control:
  Manufacturers and inspection bodies use this standard to verify that supplied textile rolls or pieces conform to customer specifications, reducing disputes over delivered quantity and usable material.

• Procurement and Supply Chain Consistency:
  Trade partners benefit from uniform fabric measurement practices when buying and selling textiles, leading to improved contract clarity and minimized ambiguities regarding the length and width of textile fabrics.

• Regulatory and Compliance Testing:
  Laboratories, industry regulators, and certification agencies assess textile conformity using this standard to ensure alignment with national and international requirements.

• Product Development and Manufacturing:
  Accurate width and length measurements are fundamental during the design and production stages for garments, furnishings, and technical textiles, affecting material yield calculations and production planning.
