(China) yy378 -Umbane wothuli

Inkcazo emfutshane:

Imveliso isebenza kwi-En149 UMGAQO-NKQUBO WOKUVAVANYA Imigangatho ehambelana: BS E149: 2001 + A1

 

Blocking test principle: the filter and mask blocking tester is used to test the amount of dust collected on the filter, the respiratory resistance of the test sample and the filter penetration (permeability) when the air flow passes through the filter by suction in a certain Imeko yothuli kwaye ifikelela kwinkcaso ethile yokuphefumla.
