Standards and labels

• EN 149:2001+A1:2009

  EN 149:2001+A1:2009 is a European standard for filtering half masks for protecting against particles and it is an amendment of EN 149:2001. It outlines additional requirements for mask design and performance testing. The mask must be able to filter a certain percentage of particles, have good breathability, and fit securely to the face. The test results shows how well the mask filters and how easy it is to breathe through, also it includes a test for the mask's ability to fit securely to the face. It also specifies the mask's ability to filter out specific airborne particles like dust, mist, and fumes. It includes additional requirements for the performance of the mask, such as the ability to seal against the face and the mask's durability.

  Test results

  Dolomite Test D

  The EN 149:2001+A1:2009 Dolomite Test, conducted within the framework of EU standards, assesses the resistance of respiratory protective filter masks to clogging by dolomite dust, thus ensuring longer-lasting filter performance under dusty conditions. A result labeled as D in the context of this test indicates that the mask has passed the dolomite dust clogging test and can maintain good breathing resistance over an extended period in a dusty environment, making it suitable for use in high particulate environments. The test method involves exposing the respiratory mask's filter to dolomite dust under controlled conditions and measuring its resistance to clogging (breathing resistance before and after exposure). After successfully passing this test, the mask can be marked with the letter D to signify its performance level, assisting employers or workers in making informed decisions regarding the level of respiratory protection required for specific industrial settings.

• CE Marking

  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.
