Technical
Data Sheet
3M™ Particulate Respirators C300 Series
Description
The 3M™ Particulate Respirators C300 Series meet the requirements of European Standard
EN149:2001 + A1:2009, filtering facepiece respirators for use against particles. They provide
effective respiratory protection for use in industries where workers will be exposed to solid
(dust) particles and/or non-volatile liquid particles.
Applications
These respirators are suitable for use in concentrations of solid (dust) particles and/or non-volatile liquid particles up to the
following limits:
*Many countries apply Assigned Protection Factors (APFs) which reduce the maximum concentrations of particles in which
these products can be used. See national regulations and EN 529:2005.
Respiratory protection is only effective if it is correctly selected, fitted and worn throughout the time when the wearer is
exposed to hazards.
Standards
Products are classified by filtering efficiency and maximum total inward leakage performance (FFP1, FFP2 and FFP3), also by
usability and clogging resistance. Performance tests in this standard include filter penetration; extended exposure (loading)
test; flammability; breathing resistance and total inward leakage. Reusable products are also subjected to cleaning, storage
and mandatory clogging resistance tests (clogging is optional for non-reusable products). A full copy of EN 149:2001+A1:2009
can be purchased from your national standards body.
Filter Penetration
The filter penetration, initial and after 120mg of loading with both 120mg of NaCl* and Paraffin Oil, shall not exceed the
following limits:
