PROTECTION AGAINST MICRO-ORGANISMS EN 374-1:2003
|
EN 374-1:2003: covers the ability of the glove to protect the user against micro-organisms. In very simple terms how likely is the glove to have a pin hole or other imperfection which would allow the glove to leak. In order to carry the “micro-organism” pictogram the glove should achieve Level 2 or above based on the table below.
