This document specifies requirements for construction, design, performance, marking, and user information. In particular, it specifies requirements regard - ing the sound attenuation of the earmuffs. EN 352-2 – Hearing protectors – General requirements – Part 2: Earplugs. This document specifies requirements for construction, design, performance, marking, and user information. In particular, it specifies requirements regard ing the sound attenuation of the earplugs. EN 352-3 – Hearing protectors – General requirements – Part 3: Earmuffs attached to head protection and/or face protection devices. This document specifies requirements for construction, design, performance, marking, and user information for earmuffs attached to head protection and/or face protection devices. In particular, it specifies require - ments regarding the sound attenuation of mounted earmuffs. • helmet type • standard no. • 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 25 311 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 the production date. SKULL PROTECTION HEARING PROTECTION LIST OF STANDARDS EN 397 - Industrial safety helmets. This norm specified structural require - ments and safety-relevant parameters, test methods and marking requirements for industrial safety helmets. Mandatory and additional requirements for safetyrelated 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 long - er 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.
