Product Technical Information
EN 397:2012
Mandatory Tests:
EN 50365: 2002 – Insulating helmets for use on low voltage installations
This standard is for helmets used for working live or close to live parts on installations not exceeding 1000 V a.c or 1500 V d.c. Testing to EN 50365 exceeds testing under EN397 for electrical properties.
Marking: double triangle + class + batch number.
EN 166:2001
Personal Eye Protection
European Standard, applying to all types of individual protection of the eye which protects from hazards likely to damage the eye, except nuclear radiation, x-rays, laser emissions and infrared emitted by low-temperature sources. Does not apply to eye protection for which separate standards exist (E.g anti-laser eye protection, sunglasses for general use).

- Impact*: Energy spread to the head form must not exceed 5kN after the fall of an object of 5 kg at 1m high.
- Penetration*: The tip of the test mass used (3 kg from 1m height) must not come into contact with the skull.
- Flammability: The helmet is exposed to a flame and it must not burn with flame emission more than 5 seconds after removal of the flame.
- Impact and Penetration tests* are performed room temperature, at +50 degrees and at -10 degrees.
Optional Tests:
- Resistance at extreme temperatures: testing impact and penetration are performed at +150 degrees, at -20 degrees or -30 degrees temperatures.
- Electrical properties: Protects against a short accidental contact with electric leads under voltage up to 440 Vac.
- Lateral deformation: Protects against lateral compressions. The maximum deformation of the helmet should be less or equal to 40mm (LD)
- Molten metal splashes: The helmet is not deformed or penetrated by splashes of molten metal (MM)
