Safety Standards
Of course, based on regulation (EU) 2016/425 on personal protective equipment (PPE) our products meet all the necessary standards, and not just that – we always require that little bit more from our products. This ensures the extra safety that our customers – rightly – expect from us.
Standard DIN EN 352 regulates general requirements for hearing protection as part of protective workwear.
Selection of appropriate hearing protection in accordance with DIN EN 352 depends on the specific working conditions and the type of noise occurring at the workplace. Requirements for hearing protection are regulated accordingly and classified into the following types:
In addition to the general requirements in accordance with DIN EN 352, product-specific features and requirements are regulated in the following special standards.
Earmuffs in accordance with standard DIN EN 352-1 are defined as hearing protectors that enclose each of the wearer's external ears with a functional capsule. As it is often desirable to frequently put on and take off ear protection in areas with variable noise exposure, earmuffs are recommended for such environments.
The various sections of standard DIN EN 352-1 on earmuff requirements also regulate:
· requirements for earmuffs attached to industrial safety helmets
· safety requirements and tests of level-dependent earmuffs
· safety requirements and tests on earmuffs with active noise compensation· safety requirements and tests on earmuffs with communication devices
Hearing protectors – General requirements – Part 3: Earmuffs attached to head protection and/or face protection devices
EN 352-3:2020 supersedes EN 352-3:2002, which is withdrawn.
EN 352-3:2020, the third section of the EN 352 standard, specifies requirements for construction, design, performance, marking and user information for earmuffs attached to head protection and/or face protection devices, hereinafter referred to as ‘mounted earmuffs.
It specifies requirements regarding the sound attenuation of mounted earmuffs, measured in accordance with EN ISO 4869-2:2018.
The Standard does not apply to earmuffs outside the size range of head sizes as defined in this standard.
Because one model of earmuffs designed to be attached to head protection and/or face protection devices can be fitted to a number of other models and sizes of the carrier, this part of the standard sets out a series of physical and acoustic requirements for earmuffs when fitted to the specified model(s) or size(s) of head protection and/or face protection device.
All requirements apply to earmuffs fitted to one of the specified models or sizes of head protection and/or face protection device (the basic combination). An abbreviated set of requirements applies to the same model of earmuffs when fitted to the other specified models or sizes of head protection and/or face protection device (the supplementary combinations).
Ergonomic aspects are addressed by taking into account, within the requirements, the interaction between the user, the device and, where possible, the working environment in which the device is likely to be used.
Marking ear muffs:
· Manufacturer/company name
· Identification or model number
· Number and date of the standard
In a calculation method carried out by the institution for statutory accident insurance and prevention, hearing protection products can be categorised as particularly suitable to specific areas of application.
