EN 352-2:2020/FprA1

Overview

EN 352-2:2020/FprA1 is a European Standard developed by CEN (European Committee for Standardization) that specifies the general requirements for hearing protectors, with a focus on earplugs. This standard sets out the essential criteria for the construction, design, performance, marking, and user information related to earplugs for effective hearing protection. The core objective is to ensure that earplugs provide adequate sound attenuation, as tested in accordance with EN ISO 4869-1:2018, and are suitable for users who can follow fitting instructions and understand the associated risks.

Key Topics

• Construction and Design: The requirements focus on ergonomic and functional design considerations to facilitate correct fit and comfort. This includes adapting the earplug design to users' anatomical differences and potential working environments.
• Sound Attenuation: Measured performance values indicating how effectively the earplugs reduce noise exposure, aligned with EN ISO 4869-1:2018.
• Marking and Packaging: Earplug products and their packaging must be appropriately marked, including the EN 352 series reference, to ensure traceability and regulatory compliance.
• User Information: Clear instructions must be provided regarding safe insertion, use, cleaning, and limitations to support proper usage and maximize protection.
• Banded Earplugs: Amendment A1 introduces modifications focusing specifically on banded earplugs, such as distinctions for over-the-head, behind-the-head, and under-the-chin configurations, as well as fitment requirements.
• Compliance with EU Regulation: The standard supports the essential requirements of EU Regulation 2016/425 regarding personal protective equipment (PPE).

Applications

EN 352-2:2020/FprA1 is relevant in sectors and situations where hearing protection is critical to health and safety, including:

• Industrial Workplaces: Manufacturing plants, construction sites, and heavy industry environments where noise exposure often exceeds safe thresholds.
• Public and Private Sector Employees: Workers in airport grounds, emergency services, and sporting events may be required to wear certified earplugs.
• Personal Protective Equipment Procurement: Occupational health and safety managers reference this standard to select compliant earplugs for employee protection.
• Compliance and Auditing: Regulatory authorities and safety inspectors use this standard as a benchmark during PPE evaluations and workplace audits.
• Product Manufacturers: Designers and manufacturers align earplug products with EN 352-2 to achieve market access within the EU and to meet customer expectations for effective hearing protection.

Related Standards

For integrative personal protective equipment strategies and broader compliance, several associated standards should be considered:

• EN 352 Series: Covers general requirements and testing for various types of hearing protectors, including earmuffs (EN 352-1), earmuffs with communication capability (EN 352-3), and helmet-mounted versions (EN 352-5).
• EN ISO 4869-1:2018: Outlines the method for measuring the sound attenuation of hearing protectors, which is referenced for verification in EN 352-2.
• EN 13819-1:2020+A1: Specifies mechanical and acoustic tests for hearing protector components and is cited in the latest amendments.
• EN 458: Provides guidance on selection, use, care, and maintenance of hearing protectors, supporting employers and users in making informed decisions.

EN 352-2:2020/FprA1 ensures the safety, comfort, and effectiveness of earplugs used throughout the European Union and internationally. By adhering to this standard, manufacturers, employers, and users can confidently address regulatory obligations and promote long-term hearing health in noise-risk environments.
