16 CFR PART 1203 – Bicycle Helmets
Category:
CPC
What Is a Bicycle Helmet?
A bicycle helmet is any headgear marketed and sold to protect bicycle riders from head injuries while riding. If a helmet is advertised as providing protection for general use or for non‑cycling activities, and a reasonable consumer would infer from the marketing that it qualifies as a bicycle helmet, it is still considered one.
Products Exempted Under 16 CFR Part 1203 for Bicycle Helmets
Helmets specifically designed for skateboarding, inline skating, baseball, or field hockey are not subject to bicycle helmet regulations.
16 CFR Part 1203 – Purpose of Bicycle Helmet Requirements
This regulation establishes performance requirements for helmets designed to protect bicyclists from head injuries from falls or collisions. Helmets that fail to meet any requirement are non‑compliant with the Consumer Product Safety Act, enforced by the U.S. Consumer Product Safety Commission (CPSC). The standard aims to reduce the risk of serious head‑impact injuries and fatalities.
16 CFR Part 1203 – Test Requirements for Bicycle Helmets
The safety requirements specify test methods for various helmet components, including the retention system. Under CPSC requirements, testing generally involves six steps.
1. Required Samples
Eight samples are needed. The manufacturer must provide a numerical value – the Helmet Positioning Index (HPI) – which defines measurements for correctly positioning the helmet on the headform.
2. Marking
The technician places the first sample on a suitably sized headform mounted upright on a stand. Using the HPI, the helmet is positioned, and a 5 kg (10.9 lb) cloth bag filled with lead shot is placed on it to compress any foam liner. The stand mark is adjusted to the position specified in the standard’s table (depending on helmet size). A marker is attached to the helmet, and the test line is marked by rotating the helmet or moving the marker holder. Each sample is marked accordingly. All impact locations must lie along this test line. To determine the line, a medium‑sized helmet is placed on the headform, a measurement of 68 mm inward from the inner surface directly below the highest interior point is taken, and that level is marked around the outer surface.
3. Preconditioning
Before testing, helmets undergo thermal, humidity, cold, and ambient conditioning. Between 4 and 24 hours prior to testing, the eight samples are exposed to conditions simulating possible use/storage scenarios:
2 samples heated to 47–53°C (117–127°F)
2 samples cooled to –13 to –17°C (55–63°F)
2 samples immersed in drinking water at 15–23°C (59–73°F)
2 samples kept dry at ambient room temperature (59–73°F)
4. Strap Test
This includes strap strength and positional stability (“roll‑off”) tests. (Test setup shown below.)
5. Drop Test
The helmet is secured on a headform and positioned upside down on a test apparatus that guides it to impact an anvil.
The tester raises the assembly until the top of the helmet reaches the specified height above the anvil, then releases it to fall freely; falling velocity is verified before impact. An accelerometer measures the acceleration (g‑force) at the headform centre. Lower g‑values indicate better protection – good helmets typically achieve below 200, superior ones below 150. Values above 300 constitute failure.
Tests use three anvil types:
1)Flat anvil, drop height 2 m (impact velocity ~14 mph)
2)Hemispherical anvil (grapefruit‑sized), drop height 1.2 m (~11 mph)
3)Curbstone‑shaped anvil, drop height 1.2 m (~11 mph)
6. Records
The CPSC standard requires laboratories to maintain test records, including helmet identification and performance data.
16 CFR Part 1203 – Criteria for Evaluating Bicycle Helmets
The helmet must pass all of the following; failure of any single test results in non‑compliance.
1.Does not obstruct peripheral vision.
2.Remains properly positioned during a fall (positional stability).
3.Retention system has sufficient strength and does not over‑stretch.
4.Significantly reduces impact force transmitted to the head.
16 CFR Part 1203 – Safety and Warning Requirements
Bicycle helmets under 16 CFR Part 1203 are required to comply with various safety and warning requirements. For example, bicycle helmets must:
1.Include a warning stating that no helmet can protect against all possible impacts and that serious injury or death may occur (Section 1203.6(a)(2));
2.Include a warning stating that a helmet may no longer provide adequate protection after an impact, even if no visible damage is present (Section 1203.6(a)(4));
3.Include a warning stating that certain household chemicals may damage helmets and that such damage may not be visible to users (Section 1203.6(a)(5)); and
4.Provide adequate peripheral vision, particularly within 105 degrees to the left and right sides (Section 1203.12).
Bicycle helmets are highly regulated products in the United States and are subject to strict safety oversight. The CPSC regularly issues product recalls and publishes safety incident reports related to bicycle helmets.
Bicycle helmets under this regulation must comply with various safety and warning provisions, including:
1.A warning that no helmet can protect against all impacts and that serious injury or death may occur (§1203.6(a)(2)).
2.A warning that a helmet may lose adequate protection after an impact, even without visible damage (§1203.6(a)(4)).
3.A warning that certain household chemicals may damage helmets invisibly (§1203.6(a)(5)).
4.Adequate peripheral vision, especially within 105° to the left and right (§1203.12).
Bicycle helmets are highly regulated in the U.S. and subject to strict safety oversight; the CPSC regularly issues recalls and safety incident reports.
