Standard Test Method for Resistance of Medical Face Masks to Penetration by Synthetic Blood (Horizontal Projection of Fixed Volume at a Known Velocity) subscription-only BS EN 61291-2:2016 constitutes a1. Scope 1. 1 This test method is used to evaluate the resistance of medical face masks to penetration by the impact of a small volume (~2 mL) of a high velocity stream of synthetic blood. Medical face mask pass fail determinations are based on visual detection of synthetic blood penetration.
