On 21 April 2018, the PPE Directive 89/686 has been replaced by the new PPE Regulation (EU) 2016/425. The EU regulation applies in all EU member states and is legally binding. The new regulation understands harmful noise as an irreversible health risk. This means that hearing protection, whether used for private or commercial purposes, is subject to stricter regulatory requirements.
Retailers and acousticians are now obliged to ensure that the hearing protection complies with the current legal requirements and that the products are tested and certified as PPE. For the products approved as PPE, the performance of a functional test is required by law.
The following specifications are binding:

  • The function test must be carried out before the first application. If the hearing protection does not pass this functional test, it must not be handed out but must be claimed to the manufacturer. Only hearing protection with a proven protective effect may be used.
  • The result of the functional test must be reported to Dreve by the acoustician to meet the requirements of EU Regulation 2016/425 on personal protective equipment.
  • The functional test must be carried out according to the manufacturer's specifications and transmitted directly via Dreve’s SmartOrder ordering platform. The result of the functional test can be printed out and shall be handed over to the user. SmartOrder archives the result of the functional test for the acoustician.
  • Furthermore, in the area of industrial safety and for safety at work and a practical briefing for the user must be carried out.

Generally, the Dreve DLO® hearing protection products should not be changed or amended. Otherwise the product is not conform to its former and approved type anymore and may therefore not be placed on the market!
This comprises:

  • Earmold and filter
  • Packaging incl. tag with product labeling

Individual comfort: DCO®

Not only at work but also in our leisure time we are exposed to different effects that can lead to hearing damages. Therefore Dreve offers a wide range of suitable earmolds. We strive for effective protection with a maximum wearing comfort.
