Update time : 2024-12-17

Overview of EN 1077:2007  

EN 1077:2007 is a European standard that defines the requirements and testing methods for ski helmets. Its primary goal is to ensure that ski helmets provide sufficient head protection, reducing the risk of head injuries during skiing activities.

 

Scope of EN 1077:2007  

EN 1077:2007 applies to helmets used in various skiing activities, such as alpine skiing, cross-country skiing, and freestyle skiing. It covers helmets for both adults and children. Ski helmets sold in European markets generally need to comply with this standard.

 

Key Components of EN 1077:2007  

Part 1: Requirements and Testing Methods for Alpine Ski Helmets

1. Structural and Material Requirements  

   - Outer and Inner Shell:  

     The outer shell must withstand potential impacts, such as collisions with rocks, ice, or other skiers. The inner shell must effectively absorb energy during impacts, minimizing head injuries.  

     - The padding inside the helmet must provide comfort while acting as a cushion. Specifications include padding thickness, softness, and elasticity to ensure both safety and comfort.  

   - Sizing and Retention System:  

     The standard specifies helmet size ranges and accuracy. Helmets should accommodate different head circumferences, and size labels must be precise to help consumers select the right fit. Retention systems, including buckles and straps, must be secure, durable, and operable even in low-temperature environments while wearing gloves.

 

2. Field of Vision Requirements  

   Helmets must provide a clear and wide field of vision. They should not obstruct the wearer’s ability to see forward, to the sides, or downward, ensuring that skiers can detect other skiers, obstacles, and signage on slopes. Vision testing uses specific optical equipment and methods to confirm compliance.

 

3. Ventilation Performance  

   Given that skiing involves sweating and varying weather conditions, helmets must include ventilation designs that allow effective airflow to remove heat and moisture while preventing excessive cold exposure. Ventilation performance is tested under simulated usage conditions.

 

4. Markings and Information Requirements  

   Helmets must display clear and durable markings, including model number, size, production date, and compliance with relevant standards. Instruction manuals should be provided, outlining proper use, fitting, and maintenance.

 

5. Testing Methods:  

   - Impact Tests:  

     Impact testing simulates various collision scenarios (e.g., frontal, lateral, and rear impacts) using specialized equipment. Helmets are preconditioned in low-temperature environments before testing to assess their performance in cold conditions.  

   - Retention System Testing:  

     Retention systems are subjected to tensile tests to check buckle and strap strength. Helmets must remain securely fastened under applied force to ensure they stay in place during accidents.

 

Part 2: Requirements and Differences for Cross-Country Ski Helmets

1. Comparison with Alpine Ski Helmets and Specific Requirements:  

   Cross-country skiing helmets differ in some aspects due to the nature of the sport:  

   - Lightweight Design: Helmets must be lighter to reduce fatigue during prolonged activities.  

   - Field of Vision: Cross-country skiing requires stricter field-of-vision requirements due to complex terrain and the need for greater peripheral awareness.  

   - Ventilation: Helmets may have enhanced ventilation to manage heat and moisture during long-distance skiing.  

   - Material Selection: Lightweight materials are preferred while maintaining sufficient strength to protect against potential impacts.

 

2. Specific Testing Methods and Considerations:  

   - Impact Tests:  

     Tests focus on specific angles and speeds that simulate collisions common in cross-country skiing, such as impacts with tree branches. Factors like the shape, hardness, and angle of impact are considered.  

   - Retention System Tests:  

     Similar tensile and durability tests are performed on the retention systems, ensuring that helmets stay securely fastened under various conditions.

 

This standard provides comprehensive guidelines to ensure ski helmets are safe, comfortable, and effective for a variety of skiing activities.
