Respiratory protective equipment -
Non-powered air-purifying particle respirator
1 Scope
This Standard specifies the technical requirements, testing methods, and
identification of non-powered air-purifying particle respirator.
This Standard applies to non-powered air-purifying respiratory protective
equipment against all kinds of particles.
This Standard does not apply to respiratory protective equipment against
harmful gases and vapors. It does not apply to the respiratory protective
equipment for hypoxic environments, underwater operations, escape, fire-
fighting.

3 Terms and definitions
The following terms and definitions apply to this Standard.
3.1 Particle
Solid, liquid or particle mixed with solid and liquid suspended in air, such as
dust, fume, mist, and microorganisms.
[GB/T 18664-2002, definition 3.1.15]
3.2 Dust
The tiny solid particles suspended in the air, which are generally produced by
the solid materials being broken by mechanical forces.
[GB/T 18664-2002, definition 3.1.16]
3.3 Fume
The tiny solid particles suspended in the air, which are generally produced by
the condensation of gas or vapor, and of which the particle size is usually
smaller than that of dust.
[GB/T 18664-2002, definition 3.1.17]
3.4 Mist
The tiny droplets suspended in the air.
[GB/T 18664-2002, definition 3.1.18]
3.5 Microorganism
Tiny creatures in nature with small shapes and simple structures which cannot
be observed directly with the eye and can only be seen under an optical
microscope or an electron microscope.
3.6 Non-powered air-purifying respiratory protective equipment
Filtered respiratory protective equipment that relies on the wearer’s breathing
to overcome the airflow resistance of the component.
[GB/T 18664-2002 , definition 3.1.3]
3.7 Tight-fitting facepiece
A facepiece that can cover the mouth and nose and fit tightly to the face, or a
facepiece that can cover the eyes, mouth, and nose and fit tightly to the head
and face. The tight-fitting facepiece is divided into a half facepiece and a full
facepiece.
[GB/T 18664-2002, definition 3.1.5]
3.8 Half facepiece
A tight-fitting facepiece that covers the mouth and nose, or covers the mouth,
nose, and jaw.
3.9 Full facepiece
A tight-fitting facepiece that covers mouth, nose, eyes, and jaw.
3.10 Disposable facepiece
A half facepiece mainly composed of a filter material, with or without an
exhalation valve, which cannot be cleaned and reused and shall be discarded
immediately when any component fails.
3.11 Replaceable facepiece
A tight-fitting facepiece with single or multiple replaceable filter elements, with
or without breathing valve, with or without breathing hose.
3.12 Inhalation valve
The check valve on the respiratory protective equipment, which only allows
inhalable gas to enter the facepiece and prevents exhaled air from exiting
through it.
3.13 Exhalation valve
The check valve on the respiratory protective equipment, which only allows
exhaled gas to exit the facepiece and prevents inhaled air from entering the
facepiece through it.
3.14 Breathing hose
A flexible, air-tight air hose for connecting a facepiece to a filter element.
3.15 Filter element
Filter materials or filter components used in air-purifying respiratory protective
equipment to filter out harmful substances in the inhaled air.
Example: canisters (filter cartridges), dust canisters, filter media, etc.
[GB/T 18664-2002, definition 3.1.22]
3.16 Filter efficiency
Percentage of particle removed by the filter element under specified testing
conditions.
3.17 Total inward leakage; TIL
The ratio OF the concentration of the simulant leaking into the facepiece from
all the facepiece components including the filter element TO the concentration
of the simulant in the inhaled air, when the subject inhales, under the testing
conditions specified by the laboratory, expressed as a percentage.
3.18 Inward leakage; IL
The ratio OF the concentration of the simulant leaking into the facepiece from
all the facepiece components other than the filter element TO the concentration
of the simulant in the inhaled air, when the subject inhales, under the testing
conditions specified by the laboratory, expressed as a percentage.
3.20 Head harness
A component for fixing the facepiece on the head.
4 Classification and marking
4.1 Classification of facepiece
According to the structure, the facepiece is divided into three types: disposable
facepiece, replaceable half facepiece, full facepiece.
4.2 Classification of filter element
Filter elements, according to the filtration performance, are divided into two
categories: KN and KP. Category KN is only suitable for filtering non-oily
particles. Category KP is suitable for filtering oily and non-oily particles.
4.3 Grades of filter element
harness of replaceable half facepiece and full facepiece shall be designed
to be replaceable;
c) There shall be as little dead space and larger field of view as possible;
e) Respiratory protective equipment which uses replaceable filter elements,
inhalation valves, exhalation valves, head harness shall be designed for
easy replacement; meanwhile it allows the user to check the airtightness
of the facepiece and face at any time and conveniently;
f) The breathing hose shall not restrict the movement of the head or the user;
it shall not affect the tightness of the facepiece; it shall not restrict or block
the airflow;
g) The structure of the disposable facepiece shall ensure close fit with the
face; meanwhile it shall not deform during service life.
5.2 Visual inspection
Check it in accordance with 6.1.
The surface of the sample shall neither be damaged, deformed, nor have other
obvious defects. The material and structure of the component shall be able to
withstand normal use conditions and the temperature, humidity, and
mechanical shock that may be encountered. The head harness shall be
adjustable. The head harness of replaceable facepiece shall be designed to be
replaceable. The lenses of the full facepiece, when wearing, shall not affect the
vision, such as fogging. After the temperature and humidity pretreatment and
mechanical strength pretreatment according to the method of 6.2, the
components shall not fall off, be damaged or deformed. The inspection shall
also include identifications and various information as provided by the
manufacturer.
5.3 Filter efficiency
USE sodium chloride (NaCl) particles to test the type N filter elements. USE
dioctyl phthalate (DOP) or oily particles (such as paraffin oil) of equivalent
nature to test the type P filter elements.
Perform testing in accordance with the method of 6.3.
In the testing process, the filter efficiency of each sample shall always meet the
requirements of Table 2.
facepiece within 60 s shall not be greater than 100 Pa.
5.15 Information to be provided by the manufacturer
