For Southeast Asian manufacturers looking to sell on Alibaba.com and access European markets, understanding CE certification requirements is non-negotiable. The EN 397 standard defines the mandatory requirements for industrial safety helmets used across the European Union and many other international markets.
The standard specifies five core mandatory tests that every CE certified safety helmet must pass before reaching the market. These requirements ensure baseline protection for workers in construction, manufacturing, mining, and other high-risk industries where head protection is critical.
Impact Absorption Testing requires the helmet to absorb energy from a 5kg striker dropped from 1 meter height, limiting force transmission to the head form to below 5kN. This simulates the most common workplace hazard: falling objects.
Penetration Resistance uses a 3kg conical striker dropped from 1 meter to ensure the helmet shell prevents sharp objects from penetrating through to the wearer's head. This is particularly critical in construction environments where nails, metal fragments, and debris pose constant risks.
The Chin Strap Release Force requirement (150-250N) ensures the strap releases under excessive force to prevent neck injury while still securing the helmet during normal use. This balance between retention and safety release is often overlooked but essential for worker protection.
The EN 397:2025 revision represents the most significant update to industrial helmet specifications in 30 years. Key changes include the new Type 1 vs Type 2 classification system, removal of the 440V electrical insulation option, and mandatory testing of helmets with accessories as a complete system [2].
The EN 397:2025 update introduces critical changes that B2B buyers and suppliers on Alibaba.com must understand:
Type 1 vs Type 2 Classification: Type 1 helmets are designed for ground-level work where impact comes primarily from above. Type 2 helmets provide additional side impact protection for workers at height or in environments with multi-directional hazard exposure.
Complete System Testing: Helmets with attached accessories (ear defenders, visors, mounting brackets) must now be tested as a complete system rather than separately. This affects procurement decisions and product configuration strategies for exporters.
Removed Options: The 440V electrical insulation option has been removed from the standard, reflecting changes in electrical safety practices and alternative protection methods.
