Head Protection
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:
- Shock absorption
- Resistance to penetration
- Flame resistance
- Chinstrap anchorage
A manufacturer can choose to submit products to a range of optional tests. Such tests could lead to one or more of these markings appearing on a helmet
-20º / +30ºc
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
Relating to industrial bump caps, which are intended to provide protection against collision with a stationary object, such as bumping against scaffolding etc. A bump cap does not provide protection against falling or thrown objects and should not be used where a safety helmet is required.
MATERIALS
- Shells are primarily made using UV stabilised HDPE (High Density Polyethylene) or ABS (Acrylonitrile Butadiene Styrene).
- Harnesses are normally made using low density Polyethylene or Terylene webbing.
