Skiing is one of the most popular winter sports and it’s only natural that safety concerns make helmets an essential part of skiing gear. But not all ski helmets are created equal – some protect better than others in case of falls or crashes on steep slopes. So, how are ski helmets safety rated?
Experts use a variety of testing methods to determine safety ratings for ski helmets. One of the most rigorously tested standards used internationally is the ASTM F2040 standard. ASTM (American Society for Testing and Materials) International is an organization that develops globally recognized test protocols for protective gear like helmets.
The ASTM F2040 standard covers several aspects of helmet performance including impact from high-speed collisions, penetration by sharp objects, retention system strength (how securely the chin strap holds the helmet in place), coverage area, and more. The standard considers different types of skiing activities such as alpine skiing, snowboarding, and extreme free-riding among others in order to ensure the rating reflects acceptable protection levels across board.

The Basics of Ski Helmet Safety
The Importance of Proper Fit
A properly fitting ski helmet is crucial to ensure maximum protection in the event of a fall or collision. A loose-fitting helmet can shift during an impact and fail to provide adequate protection, while a helmet that is too tight can cause discomfort and headaches, leading to distractions on the slopes.
To determine the correct size for your ski helmet, measure the circumference of your head just above your eyebrows and consult the manufacturer’s sizing chart. Adjustable straps and padding allow for customization of fit within each size range. It is important to also try on different brands and models to find the helmet that fits your unique head shape best.
Remember, never buy a used helmet as it may have been damaged in a previous impact and will not provide reliable protection.
Materials Used in Ski Helmet Construction
Ski helmets are generally made from a combination of hard plastic on the exterior and foam, typically expanded polystyrene (EPS), on the interior. Some higher-end helmets may use more advanced materials such as multi-density foams, carbon fiber, or Kevlar to provide increased strength and lightness.
In addition to the main structure of the helmet, many manufacturers include additional features such as ventilation systems, ear pads, and visors/face shields to improve comfort and usability.
It is essential to choose a helmet manufactured by a reputable company that uses high-quality materials to ensure maximum safety and effectiveness.
Impact Testing Standards for Ski Helmets
To evaluate the level of protection provided by ski helmets and to ensure they meet rigorous safety standards, independent organizations conduct testing using controlled impacts simulating potential real-life accidents.
The most common standard for evaluating ski helmet safety is ASTM F2040, which establishes minimum requirements for impact attenuation, penetration resistance, retention system strength, and field of vision. Helmets that meet this standard will include a certification sticker or label on the inside of the helmet.
Manufacturers may also choose to voluntarily adhere to additional standards such as CE EN 1077, which includes testing for low-temperature impact performance, or Snell RS-98, a more rigorous standard used in competitive skiing and racing.
Understanding ASTM F2040 Safety Standards
Design and Construction Requirements
Ski helmets are essential to protect the head from potential injury caused by accidents or falls, but not all helmets provide equal protection. Standards such as ASTM F2040 exist to ensure that ski helmets provide consistent levels of safety across different brands. The standards specify design and construction requirements that must be followed in order for a helmet to pass certain tests.
One requirement is that the helmet should have a hard, protective outer shell made from materials like ABS plastic or polycarbonate. Inside, it should have a layer of energy-absorbing material, often made from foam, which helps reduce impact forces. The chinstrap should also be durable enough to keep the helmet secured during impact.
All these features work together to make sure a ski helmet provides adequate protection. Brands can choose their own designs and colors but need to adhere to the underlying structural requirements to allow each helmet to properly function when needed.
Performance Testing Procedures
The ASTM F2040 standard recommends five primary testing procedures to evaluate the performance of a ski helmet:
- Drop test: Helmets are dropped on a smooth projecting hemispherical anvil from various heights at different angles to simulate real-life impacts and determine the force reduction experienced by someone wearing the helmet.
- Penetration test: A sharp striker is dropped onto the helmet to check if any portion breaks through and reaches the headform inside.
- Cold temperature test: The helmet stays in temperatures as low as -20°C (-4°F) and is then subjected to drop and penetration tests to gauge how well it holds up in extreme weather.
- Retention system test: The chinstraps go through various cycles of stretch, overload, opening, and closing to check for strength and reliability.
- Peripheral vision test: Two curved rods mounted on a helmet model are adjusted in different positions to see if they fall within certain limits based on the wearer’s field of view.
The test reports generated using these procedures help customers decide which ski helmets best match their expectations and needs.
How ASTM F2040 Compares to Other Safety Standards
In addition to the ASTM F2040 safety standard, there are other standards that assess the quality of bike or snow sport helmets as well. Some examples include the EN1077 (European Norm), CPSC (Consumer Product Safety Commission), and Snell Memorial Foundation ratings. All standards aim to ensure maximum protection with rigorous testing of each helmet.
Whereas the ASTM F2040 tests focus solely on ski and snowboard helmets, bike helmets are assessed by a different set of standards known as CPSC requirements. Moreover, EN1077 is similar to ASTM but also includes product evaluation across wet, cold, and UV exposed environments. Any manufacturer can choose to comply with multiple standards like snow sport helmets that will meet both ASTMF2040 and EN1077 requirements.
“Conforming to multiple standards guarantees that a product has met high-quality benchmarks tested through careful inspections and stringent measures.”
Certification and Approval Processes for Ski Helmets
Third-Party Testing and Certification Bodies
Ski helmets are tested by third-party organizations to ensure they meet safety standards. These testing and certification bodies vary by country and region, but some common ones include:
- The International Organization for Standardization (ISO)
- The European Committee for Standardization (CEN)
- The Snell Memorial Foundation
- The American Society of Testing Materials (ASTM)
To be certified by one of these bodies, ski helmets must go through a rigorous testing process that includes impact tests, penetration tests, and strap strength tests.
Regulatory Approval Requirements for Ski Helmets
In most countries, ski helmets are required to meet specific regulatory approval requirements before they can be sold or used on the slopes. These approval requirements typically require helmets to meet certain safety standards set by national or regional governments.
In the United States, the Consumer Product Safety Commission (CPSC) sets helmet safety standards under the Federal Consumer Product Safety Act. In Europe, helmets must meet the CEN EN 1077 standard, which is approved by the European Union.
How to Ensure Your Ski Helmet is Certified and Approved
If you want to make sure your ski helmet is certified and approved, look for a label or sticker indicating that it meets safety standards set by a recognized organization. You should also check the helmet’s documentation to see if it has been certified by one of the testing bodies mentioned above.
Remember that wearing a certified and approved ski helmet is important for protecting yourself on the slopes. Don’t skimp on safety – always choose a high-quality, well-tested helmet!
