Detailed explanation of key technical parameters
The standard divides men's chest protectors into two categories: Karate-specific type and Mixed martial arts type:
- Size system: 5 sizes are divided based on the user's height/weight, with a total width range of 785-840mm

Key points of the test method
The impact performance test adopts a steel anvil + pressure ring system:
- Anvil specifications ≥ 350×300×20mm
- Pressure ring mass 10kg±0.1kg, inner diameter 140mm±0.1mm
- At least 3-6 impact points are tested for each sample
Background of standard evolution
