Abstract

Overview

ISO 20740:2019 - "Martial arts - Wushu Taiji sword - Requirements and test method" defines international requirements, test methods and marking rules for Wushu Taiji (Tai Chi) swords used in sport. The standard covers terms and product structure (pommel, hilt, guard, blade), permitted materials, dimensional and mass tolerances, mechanical and surface performance (elasticity, coating adhesion, corrosion resistance), safety limits and marking (Taiji symbol placement). ISO 20740:2019 helps ensure consistent quality, safety and interchangeability of Taiji (Tai Chi) swords for manufacturers, testing labs and sporting bodies.

Key topics and technical requirements

Materials: Blade materials limited to manganese steel or stainless steel; hilt and scabbard may be wood.
Dimensions & tolerances: Blade and hilt length models specified (blade lengths from ~700 mm to 900 mm with permitted deviations; hilt lengths 105–120 mm). Pommel, guard and blade width/thickness ranges are defined (e.g., pommel 45–50 mm long, guard 80–120 mm wide).
Mass tolerances: Model-specific masses are listed (range examples: 0.400 kg to 0.590 kg) with tight deviations (±0.005 kg).
Elasticity / straightness: After a standardized bend test, blade straightness deviation must be
