Key Distinction: Ballistic Protection vs. Riot Protection
The bottom line: Ballistic helmets can stop bullets but may not withstand blows from clubs; riot helmets can withstand impacts and punctures but absolutely cannot stop bullets.
The design logic for the two differs completely:
Ballistic helmets: The primary mission is to prevent penetration. When facing high-speed projectiles or shrapnel, they must withstand the impact head-on, relying on high-strength fibers (such as aramid or UHMWPE) to "catch" the projectile and disperse the energy across the entire shell. The key performance metric is "back-face deformation" (or indentation depth)-while the bullet must not penetrate, minimizing the deformation on the inner surface is crucial.
Riot helmets: The primary mission is to protect against blunt force impacts and punctures. When facing clubs, stones, or even slashing and stabbing weapons, they must absorb impact energy to prevent head injuries or penetration. Key metrics include the amount of impact force transmitted to the head and resistance to penetration.
Simply put: Ballistic helmets handle bullets, while riot helmets handle blunt and sharp objects. Wearing a riot helmet into a gunfight would have disastrous consequences.
Standards Are Key: Understanding Critical Metrics
When selecting equipment, understanding the standards is essential. Currently, the two most authoritative standards in China are:
1. GA293-2012 "Police Ballistic Helmets and Face Shields"
This is the "gold standard" for ballistic helmets. Taking the common Level 2 protection as an example, the helmet must stop a Type 51 7.62mm lead-core bullet fired from a Type 54 7.62mm pistol.
Just how rigorous are these requirements?
Five shots must be fired (front, back, left, right, and top) under various conditions-ambient temperature, high temperature, low temperature, and after water immersion-with absolutely no penetration allowed.
Maximum indentation depth: ≤15mm at ambient temperature; ≤10mm after water immersion.
Ballistic limit (V50 value): ≥660m/s; this is a critical indicator of shrapnel protection capability.
Some procurement projects require Level 3 protection, capable of withstanding fire from a Type 79 7.62mm submachine gun. Higher protection levels come with increased weight and cost. 2. GA294-2023 "Police Riot Control Helmets"
This is the latest standard for riot control helmets. Its testing criteria differ significantly from those for ballistic helmets:
Impact energy absorption: A 5.0 kg hemispherical striker impacts the top of the helmet with 49 J of energy; the force transmitted to the headform must not exceed 4900 N, and the shell must not crack.
Penetration resistance: A 3.0 kg conical striker impacts the top of the helmet with 88.2 J of energy; no penetration is permitted.
Visor impact strength: A 1 g lead projectile fired at the visor at a speed of 150 ± 10 m/s must not cause penetration or shattering.
Light transmission: ≥85%; must feature anti-fog and anti-scratch treatments.
An "Advanced Lesson" on Ballistic Helmets: What is the V50 Value?
If you follow high-end ballistic helmets, you will inevitably encounter the concept of the V50 value. It refers to the ballistic limit velocity at which there is a 50% probability of penetration; the higher the value, the greater the fragmentation protection capability.
For example, a Level II ballistic helmet (Public Security standard) made of DuPont™ Kevlar® can achieve a V50 value of 676.5 m/s, whereas Level III ballistic helmets typically require a value above 650 m/s.
Regarding materials, the mainstream choices are aramid (Kevlar) fiber and ultra-high-molecular-weight polyethylene (UHMWPE) fiber. The former offers superior heat resistance, while the latter is lighter; each has its own advantages. A compliant aramid ballistic helmet must have an areal density of ≥355 g/m² and a breaking strength of ≥12.8 kN in both warp and weft directions.
Purchasing Advice: Spend Wisely
If you are a procurement officer or an experienced enthusiast, keep these points in mind:
Determine the scenario before the type: For riot control and emergency response missions, choose a riot helmet meeting the GA294 standard; for high-risk security missions, choose a ballistic helmet meeting the GA293 standard.
For ballistic helmets, focus on back-face deformation (BFD) and the V50 value: A BFD of ≤15 mm is the baseline requirement, and a higher V50 value is preferable. For riot helmets, focus on impact and puncture test data: they must meet the standards of 49J for impact resistance and 88.2J for puncture resistance.
Do not overlook the visor: the visor must have a light transmission rate of at least 85% and feature anti-fog and anti-scratch capabilities; otherwise, performance in actual operations could be severely compromised.
Official test reports are the ultimate proof of quality: look for reports issued by the Ministry of Public Security's Quality Testing Center for Security and Police Electronic Products or the China Ordnance Equipment Special Product Quality Supervision and Testing Center.
