2.How long can the old EN149:1991 respirators
At this stage, there
is no fade-out time for old EN149:1991 norms.
Manufacturers can continue to produce EN149:1991
respirators if they maintain the valid certificate.
However, commercial pressure from the customers

by June 2002 and will supply only EN149:2001 products
