The standard sets out the requirements for the construction, design, performance, labelling and user information of ear muffs. EN352-2 - Hearing protectors - General requirements - Part 2: Noise inserts. The standard sets out requirements for the construction, design, performance, labelling and user information of antinoise earplugs. EN352-3 - Hearing protectors - General requirements - Part 3: Ear muffs attached to an industrial safety helmet. The standard specifies requirements for the construction, design, performance, labelling and user information of ear muffs adapted to industrial helmets. • helmet type • standard number • CE marking • manufacturer identification • symbol of the material from which the helmet shell is made of acc. to EN ISO • 472 (ABS, PC, HDPE etc.) • Size • product marking • additional information • Production date (year, month, day) L10401 EN 397:2012 TYPE1, CLASE l l l l l l l l l l l l l l l l l l l l l l l l l 5 10 15 20 2 5 311 1 2 3 4 5 6 7 8 9 10 12 1 5 1 6 1 7 1 8 1 9 2 0 Helmet durability Helmet production date is embossed on the internal side of the shell (most often on a brim). It is encoded in the form of three shields. The head of the arrow located in each shield indicates accordingly: year, month and day of production. The helmet maintains full protective properties for 2 years from the date of entry into use, however not longer than 3 years from he production date. SKULL PROTECTION HEARING PROTECTION MARKING OF HELMETS SIZE 53-64 cm HDPE XX LIST OF STANDARDS EN 397 - Industrial safety helmets. This norm specified structural requirements and safety-relevant parameters, test methods and marking requirements for industrial safety helmets. Mandatory and additional requirements for safety- -related parameters have been established. Mandatory requirements • shock absorption (impact energy transmitted to a headform may not exceed 5 kN during free-fall of a 5 kg striker from the height of 1 m) • resistance to penetration (a 3kg punch from the height of 1 m may not deform the helmet in such a way, so as to touch the headform) • flame resistance (burner’s flame at an angle of 45 degrees from vertical should be at a distance from 50 to 100 mm and come in contact with the top of the shell for 10 s. The helmet shell may not burn and spread fire for longer than 5 s after its discontinuation) Additional requirements: • shock absorption in very low temperatures -20°C or-30°C • shock absorption in very high temperature + 150°C • electrical insulation - 440 Vac • longitudinal deformations - LD • molten metal splashes - MM Basic parameters of the EN352 standard • adjustment possibility - possibility of adjustment of the ear-muffs to heads with various sizes is evaluated • headband pressure - maximum headband pressure amounts to 14 N • noise reduction bowl pressure - maximum pressure of noise reduction cushions amounts to 4500 Pa • resistance to damage - the product is dropped from the height of 1.5 meter into a steel plate • flammability - product surface is touched with a bar heated to 650°C ± 20°C for 5 seconds; the surface must not light up or ignite after withdrawal of the bar.
