HEAD PROTECTION 6 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 1000V AC or 1500V DC, testing to EN 50365 exceeds testing under EN 397 for electrical properties. EN 397:2012 Industrial Safety Helmets Mandatory Tests: • Impact: Energy spread to the head form must not exceed 5 kN 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 at room temperature, at +50°C, and at -10°C. Optional Tests: • Resistance at Extreme Temperatures: Testing impact and penetration are performed at +150°C, at -20°C or -30°C temperatures. • Electrical Properties: Protects against short accidental contact with electric leads under voltage up to 440V WAC. • Lateral Deformation: Protects against lateral compression. The maximum deformation of the helmet should be ≤40 mm (LD). • Molten Metal Splashes: The helmet is not deformed or penetrated by splashes of molten metal (MM). EN 12492:2012 Helmets for Mountaineers This standard covers specialist mountaineers’ helmets and it includes tests on retention system strength and effectiveness to ensure the helmet is not inadvertently removed. To reflect the nature of the use, Impact and penetration tests are conducted on different points around the shell. Mountaineer requirements also apply to wearers working at height. ANSI/ISEA Z89.1:2014 American National Standard for Industrial Head Protection • Type I - Hard hats are designed only to withstand top impacts. • Type II - Hard hats designed to withstand impacts from the top and the side. • Class C - Conductive Helmet = The hard hat will not protect the wearer from electrical hazards. • Class G - General Helmet = Helmet can withstand an electrical current of up to 2,200 volts. • Class E - Electrical Helmet = Helmet that provides the highest level of electrical protection, withstanding currents up to 20,000 volts.
