Standards and labels
EN 352-3:2020 is a European standard that sets safety requirements for earplugs worn in industrial and similar environments. It covers the performance requirements for noise reduction, usability and durability. Test results for earplugs should show the level of noise reduction achieved (expressed in decibels) and how well the earplugs stay in place during use.
CE Marking is a label that shows a product meets certain safety and environmental standards set by the European Union. To get the CE Marking, a company must test and certify their product meets these standards. CE Marking is required for many products sold in the EU, including electronics, machinery, toys and medical devices. It helps ensure that products are safe for consumers and the environment, and allows for easy trade within the EU.
