SUMMARY DATA SHEET AVON CBRNF12B FILTER
P/N: 71510-1
The Avon CBRNF12B lter canister meets the relevant criteria speci ed
in the new NIOSH CBRN APR standard at the 15-minute classi cation
level (Cap 1). It provides e ective protection against all the gaseous
agents speci ed in the NIOSH standard, as well as excellent performance
against a wider range of both chemical warfare agents and Toxic
Industrial Chemicals (TICs). A particulate lter element exceeding the
requirements of NIOSH 42CFR84 P100 level is incorporated, ensuring
e ective performance against all dusts, mists, fumes, biological agents
(bacteria, virus, fungal spores etc), including radioactive dusts. CBRNF12B
is currently certi ed by NIOSH as a CBRN Cap 1 APR lter. When combined
with an appropriate chemical protective mask, the CBRNF12B lter canister
protects the face, eyes and gastro-intestinal tract of the wearer against all
known chemical and biological agents in aerosol, liquid and vapor form
including:
a. Nerve Agents
“G” Series
“V” Series
Any thickened form of agent
b. Blister Agents
Mustard
Lewisite
Any thickened form of agent
c. Blood Agents
Hydrogen Cyanide
Cyanogen Chloride
d. Riot Control Agents
CS
CN
OC (Pepper Spray)
Chloropicrin
The protection against many Toxic Industrial Chemicals (TICs) includes,
but is not limited to: organic vapors with a boiling point over 65°C,
chlorine, hydrogen sul de, sulfur dioxide, formaldehyde, nitrogen dioxide,
phosgene, phosphine and ammonia.
EFFECTIVENESS
Against Chemical and Biological Agents
Performance against the gaseous agents speci ed in the NIOSH CBRN APR
standard and also for chemical warfare agents is detailed in the adjacent
column. Note that the protection time is indicated for standard test conditions.
THESE DO NOT NECESSARILY RELATE TO ACTUAL USE TIMES. Actual use times
must be veri ed on the basis of a risk assessment of the likely hazards present
in the intended use area.

The lter canister has been tested for particulate aerosols in accordance
with NIOSH 42CFR84 P100 using hot DOP aerosol at 85 l/min. The
penetration through the canister was found to be less than 0.001% (1 in
105).
The CBRNF12B also meets the performance requirements of European
standard EN141, A1B2E1K1P3 speci cation. An appropriately marked CE
variant is available (70010/23/1) which is approved to PPE directive 89/686/
EEC by TNO certi cation.
DESCRIpTION
Construction materials
The canister body is made of Noryl, a polyphenyloxide co-polymer, which is
a high quality engineering construction polymer. It provides a very robust
product which is extremely durable against shock and impact in opera-
tional use. The canister body is black in color.
Gas absorption is by proprietary chrome free activated charcoal
impregnated with metallic salts and other compounds to provide a bal-
anced performance against both physically and chemically adsorbed
species.
The high e ciency lter element is made of glass ber/vinyl on copolymer
co-pleated with polypropylene net for structural strength.
The CBRNF12B is entirely non-ferrous and non-magnetic.
