Accredited audio lab
Combitech's audio lab is accredited by SWEDAC for testing of ear muffs and ear plugs (per the EN-352 standard). The accreditation covers even ear muffs and ear plugs that communicate via Bluetooth.
The audio lab is accredited to conduct testing according to all methods from EN 352-1 to EN 352-8 standard, which allows for testing of most types of hearing protection and earplugs.
Upon completion of the accredited testing of the hearing protection/ear plug an issued and accredited measurement protocol is used in the subsequent certification process.
All types of hearing protection devices sold in an ESS-country must be type inspected and CE labelled. The inspections are made by a notified body, which is an independent organization appointed by Swedac. Swedac is the government agency in Sweden that assesses the candidate's skills against current standards and directives and reports to the European commission. The certification bodies are listed in the database Nando at the European Commission.
