When choosing a helmet (for cycling, skateboarding, or skiing), you’ll often see labels like CPSC, CE, or ASTM on the inside. These are not brand names—they are safety certification standards.
In short: CPSC is the mandatory legal standard in the U.S.; CE is the mandatory mark for the EU market; ASTM is a higher, voluntary standard designed for specific extreme sports.
Here’s a detailed breakdown.
Full Name: Consumer Product Safety Commission
Type: Mandatory. Any bicycle helmet sold in the U.S. must pass this certification.
Standard: 16 CFR Part 1203
What it tests:
Impact: Simulates a head hitting a flat surface or curb at roughly 14 mph (22.5 km/h) . The impact force transmitted to the head must not exceed 300g (a measure of concussion risk).
Retention System: Tests the chin strap to ensure it doesn’t break or unbuckle during a crash.
Best for: Road cycling, commuting, casual riding. If a helmet only has CPSC certification, it’s safe for regular falls, but it’s not designed for skateboarding or BMX.
Full Name: Conformité Européenne (European Conformity)
Type: Mandatory. Any helmet sold in the European Economic Area must have the CE mark.
Standard: The specific standard for bike/skate helmets is EN 1078.
Difference from CPSC:
Speed: EN 1078 tests impacts at a slightly lower speed (about 12.5 mph / 20 km/h).
Coverage: CPSC requires the helmet to cover more of the head and includes a test for hitting a "kerb" (curb-shaped anvil), which EN 1078 does not strictly require.
Verdict: While both are legitimate safety standards, the industry generally considers CPSC to be slightly more rigorous than the base EN 1078. Many modern helmets sold globally carry both CPSC and CE (EN 1078) stickers.
Full Name: American Society for Testing and Materials
Type: Voluntary (but highly recommended for specific sports). These standards address risks that CPSC/CE do not cover.
Key Variants:
ASTM F1447: Recreational cycling (largely overlaps with CPSC).
ASTM F1952: Downhill (DH) mountain biking, BMX racing. This is a critical standard. It requires helmets to withstand multiple, consecutive impacts (common in downhill crashes where you tumble) and requires greater coverage for the back of the head.
ASTM F1492: Skateboarding, roller skating, trick BMX. Designed for multi-impact scenarios and smaller, repeated falls common in skateparks.
Key Point: If you do downhill mountain biking, dirt jumping, or skatepark riding, a CPSC or CE-only helmet is insufficient. Standard bike helmets are designed for a single hard impact (the foam crushes once). ASTM-certified helmets (especially F1952) are built thicker and are designed to survive multiple hits.
You’ll often see a yellow MIPS label inside helmets. Here’s how it fits in:
MIPS (Multi-directional Impact Protection System) is a technology, not a certification.
The difference: CPSC/CE/ASTM test for linear (straight-on) impacts. Real-life crashes are usually angled, creating rotational force on the brain. MIPS adds a low-friction layer inside the helmet to reduce that rotational force.
Buying tip: Look for helmets that have the correct certification (CPSC/ASTM) plus MIPS (or similar technologies like WaveCel). This is currently the highest level of safety available for consumers.
| Certification | Type | Best For | Key Feature |
|---|---|---|---|
| CPSC | Mandatory (USA) | Road cycling, commuting | 14mph impact test; wide coverage |
| CE (EN 1078) | Mandatory (EU) | Road cycling, skate, rollerskates | 12.5mph impact test; EU market access |
| ASTM F1952 | Voluntary (Recommended) | Downhill MTB, BMX Race | Multiple impacts, extended rear coverage |
| ASTM F1492 | Voluntary (Recommended) | Skatepark, Trick BMX | Multi-impact for park/street terrain |
Commuting / Road cycling: Look for CPSC (if in US) or CE (EN 1078) .
Mountain biking (Trail/Enduro/Downhill) : You need ASTM F1952 (often labeled as "DH" or "Park" certified).
Skatepark / BMX: You need ASTM F1492.
Regardless of the certification, if your budget allows, choose a helmet with MIPS. It adds critical protection against rotational forces that standard certifications don't measure.
Note: Helmets are consumables. Even if you never crash, replace your helmet every 3 to 5 years. Sweat, UV rays, and material degradation reduce its protective ability over time.
