EN Standards – Europe
EN 12492
This European standard applies to mountaineering helmets and sets out requirements for shock absorption, penetration resistance, retention system strength, field of vision, and chin strap strength. It is specifically designed for head protection in mountaineering, climbing, and related activities. EN 12492 helmets are tested to withstand the specific hazards associated with these activities, such as impacts from falling objects and rocks. Requirements include:
-
Shock absorption, vertical, frontal, lateral, dorsal
-
Penetration resistance
-
Carrier element (chin strap releases at min. 500N)
-
Strength of carrier element: Chin strap may exhibit maximum elongation of 25mm
-
Carrier element effectiveness: Helmet must not slide from the head
EN397
Another European standard, EN 397, is more general and covers industrial safety helmets. It focuses on head protection in industries like construction, mining, and manufacturing. EN 397 helmets must meet requirements related to shock absorption, penetration resistance, flame resistance, chin strap strength, and electrical insulation. They are tested for protection against falling objects, impact energy, and resistance to penetration by sharp objects.
- Shock absorption, vertical
- Penetration resistance (against sharp and pointed objects)
- Flame resistance
-
Chin strap attachment: chin strap releases at minimum 150N (Newtons) and maximum 250N
Additional specifications are provided for ear muff attachment points and chin strap attachment points.
AS/NZS 1801
This standard is specific to Australia and New Zealand and applies to industrial protective helmets. AS/NZS 1801 sets out requirements for construction, materials, shock absorption, penetration resistance, and retention system strength. It includes tests for resistance to impact, penetration, flame, and electrical conductivity. AS/NZS 1801 helmets are used in various industries and workplaces throughout Australia and New Zealand.
EN 50365
Standard covers insulating helmets aimed at use on low voltage installations, which must provide protection against electric shocks and prevention of dangerous electric current passing through the head. Requirements include:
-
All helmets must also meet the requirements in accordance with EN 397
-
Protection against alternating voltage of up to 1000 V (AC) or direct voltage up to 1500 V (DC)
-
Insulating helmets must not contain any conductive parts
-
Air vents (if available) must not allow any accidental contact with live parts
-
EN 14052: Standard covers high performance industrial helmets, which must provide protection against falling objects and lateral impact along with the resulting damage to the brain, skull, and neck. Requirements include:
Shock absorption, vertical, and lateral
-
Penetration resistance, vertical, and lateral
-
Fastening system yield: Chin strap yields at minimum 150N and maximum 250 N
-
Fastening system effectiveness: During the shock absorption and penetration test, the helmet
-
must not become detached from the test head
-
Flame resistance
While these standards differ in certain aspects, they all aim to provide adequate head protection in their respective applications. When selecting a helmet, it is important to consider the specific industry requirements and hazards involved to ensure compliance with the appropriate standard. Additionally, it is crucial to follow the manufacturer's instructions and replace helmets after any significant impact or when they no longer meet the required standards.
