EN 397 specifies physical and performance requirements of industrial safety helmets. Certain tests are mandatory if the product is to receive EN 397 approval.
These cover:
A manufacturer can choose to submit his products to additional optional tests. Such tests could lead to one or more of these markings appearing on a helmet.
-20°/-30°C The helmet will provide some protection when worn in an environment at or above this temperature
440V a.c. The helmet will protect against short term, accidental contact with live electrical conductors up to this voltage
LD The helmet will provide some protection from lateral compressive loads
MM Molten Metal splash test
EN 812 is the standard for Industrial Bump Caps, which are intended to provide protection against bumps caused by walking into hazardous projections. A Bump Cap does not provide protection against falling or thrown objects and should not be used where a safety helmet is required.
To comply with European Standards, all helmets are marked with the quarter or month and year of manufacture. If helmets are stored in boxes in which they were supplied and do not experience environmental extremes, the shelf life of a helmet is not limited. However, it is not recommended that a helmet should be in use 5 years after date of manufacture.
All helmets can be personalised with your company name or logo - contact your nearest branch for details.
