EN 352-1: Hearing protection - General requirements - Part 1: Ear-muffs
EN 352-1: 2002 specifies requirements for materials and construction, design, performance, marking and user information for ear-muffs. It specifies the sound attenuation of the ear-muffs, measured in accordance with EN 24869-1. Ergonomic aspects are addressed by taking into account, within the requirements, the interaction between the wearer, the device and where possible the working environment in which the device is likely to be used.
For industrial applications, the Control of Noise at Work Regulations 2005 came into force in 2006 which reduced the starting point for ear protection from 85 dB to 80 dB. Workers must be informed and provided with training when noise levels reach 80 dB (was 85 dB) and protection should be made available. Protection must be provided by the employer when sound levels reach 85 dB or above.
Marking ear muffs:
• Manufacturer/company name
• Identification or model number
• Number and date of the standard
• When required- e.g. “Top “and/or “Left “and “Right”
