Independent Third-Party Lab Testing & Certifications
The BOLLSEN Life+ and BOLLSEN New Sound earplugs are independently tested and certified by PZT GmbH, Notified Body No. 1974, headquartered in Wilhelmshaven, Germany. PZT GmbH is officially recognized by the Zentralstelle der Länder für Sicherheitstechnik (ZLS) as a notified testing institute for personal protective equipment (PPE) in the European Union.
In March 2024, PZT conducted a Supervised Product Check (Module C2) for BOLLSEN under the European safety standard EN 352-2:2020 and the PPE Regulation (EU) 2016/425. The report (No. 2322401-1 Rev.0) confirmed that the BOLLSEN New Sound Earplug fully complies with all essential health and safety requirements.
The independent laboratory measurements verified an average Sound Noise Reduction (SNR) of 24 dB, with frequency-specific attenuation values of H = 26 dB, M = 21 dB, and L = 19 dB, tested under controlled environmental conditions (22 ± 5 °C, < 85 % humidity) according to EN 13819-1:2020.
These results confirm consistent production quality across all samples and validate BOLLSEN’s commitment to European-made certified hearing protection.
