ISO 20739:2019

Overview

ISO 20739:2019 - Martial arts - Wushu Taiji clothing - Requirements and test methods defines classifications, technical requirements and test methods for adult Wushu (Taiji) clothing made of textile fabrics. The standard sets out garment characteristics, sizing tables, material and appearance requirements, and laboratory test methods to ensure safety, performance and consistent quality of Taiji uniforms used for practice, demonstrations and competition.

Keywords: ISO 20739:2019, Wushu Taiji clothing, Taiji uniform, martial arts clothing, textile test methods

Key Topics

• Scope and classification
  • Applies to textile Wushu Taiji clothing for adult users.
  • Classifies garments by user (men’s / women’s) and structure (jackets, bloomers/pants).
• Design and construction
  • Defines characteristic features: Chinese stand collar, Chinese frog buttons, monolithic even sleeve, duijin style front, lantern sleeves, bloomers pants.
  • Specific design requirements (e.g., jackets with 7 pairs of frog buttons, side slits, sleeve cuff details).
• Measurements and sizes
  • Detailed sizing tables for men’s and women’s jackets and pants across multiple sizes (from XS to 5XL / 3XL depending on gender) with tolerances for production.
• Material and performance properties
  • Fabric selection criteria emphasizing air permeability and drape suitable for Taiji movement.
  • Required properties include dimensional stability to washing, colour fastness (water, washing with soap, perspiration), crease resistance, tear and seam strength, pH, formaldehyde limits and checks for certain aromatic amine dyes.
• Appearance and workmanship
  • Guidelines on acceptable change in colour, defects in aspect and stitch density of sewing.
• Test methods
  • Specifies laboratory test procedures and references to established ISO textile test standards for reproducible assessment.

Applications

ISO 20739:2019 is useful for:

• Manufacturers and designers of Taiji uniforms to ensure compliant product specifications
• Quality assurance and testing laboratories performing textile and garment tests
• Retailers and importers/exporters verifying conformity for international trade
• Sports federations, event organizers and instructors setting procurement or uniform rules
• Consumers seeking assurance of safety, durability and appropriate fit for Wushu Taiji practice

This standard supports consistent product quality, athlete comfort and consumer safety while facilitating international trade in martial arts clothing.
