Sir Safety System Mesh Respirator FFP3 NR D W/V

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

  Reusability NR - Not Reusable

  The standard EN 149:2001+A1:2009 designates a classification for filtering half masks, distinguishing between those that are re-usable (R) and non-reusable (NR). When a mask is classified as NR - Not Reusable, as per the result identified for EN 149:2001+A1:2009 NR, it implies that the mask is intended for single use only and should not be used more than once. The test method for determining reusability under this standard involves assessing the mask's material integrity, filter efficiency, and structural stability after simulated use, which might include cleaning, disinfection, and aging procedures. The practical implications of this result are significant; masks labeled as NR must be discarded after one use, highlighting a critical consideration for procurement professionals in terms of inventory, cost management, and usage protocols to ensure safety and compliance.

  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.
