ISO 3759:2011 is officially titled:
"Textiles — Preparation, marking and measuring of fabric specimens and garments in tests for determination of dimensional change"
This standard outlines a unified method for preparing, marking, and measuring fabric samples and garments before and after undergoing dimensional change tests (e.g., washing, dry cleaning, steaming).
It applies to both woven and knitted fabrics, and to ready-made garments tested for shrinkage, stretch, or dimensional stability under various conditions.
When testing textiles for shrinkage or elongation, incorrect or inconsistent sample preparation can lead to:
❌ Unreliable test results
❌ Product non-conformity
❌ Increased returns and customer complaints
❌ Failure to meet brand or retailer requirements
ISO 3759 ensures that every fabric test starts with a consistent and controlled procedure, enabling dependable comparisons across different testing labs and manufacturing units.
Implementing ISO 3759-compliant procedures ensures consistent and reliable results across dimensional change tests:
🎯 Standardized Sample Preparation
Ensures each specimen is prepared under identical, repeatable conditions.
📏 Accurate and Repeatable Measurements
Provides a consistent framework for marking and measuring shrinkage or growth.
👗 Applies to Both Fabrics and Garments
Can be used during product development, production, or final inspection.
🧪 Essential for Other ISO Textile Tests
Acts as the foundational procedure for shrinkage testing under ISO 6330 (washing) and ISO 3175 (dry cleaning).
📋 Globally Recognized
Used by testing labs, brands, and factories worldwide for fabric performance assurance.
By implementing ISO 3759 with GMC’s consulting expertise, your organization gains the following business advantages:
✅ Improved Product Consistency
