Technical specification of daily protective mask
1 Scope
This Standard specifies the terms and definitions, grading, technical requirements, test
methods, inspection rules, packaging, marking, storage and transportation
requirements of daily protective masks.
This Standard applies to protective masks wore in the daily life to filter out particulate
matters in the air pollution environment.
This Standard does not apply to respiratory protection products used in hypoxic
environments, underwater operations, escaping, fire protection, medical and industrial
dust prevention and other special industries, nor for respiratory protection products for
infants and children.

3 Terms and definitions
For the purpose of this document, the following terms and definitions apply.
3.1
Particulate matter (PM2.5)
Particulate matters in the ambient air with aerodynamic equivalent diameter of less
than or equal to 2.5 μm, also known as fine particulate matters.
[GB 3095-2012, definition 3.4]
3.2
Filter efficiency
Under the specified conditions, the ability of the mask body to filter out particulate
matters, expressed as percentages.
3.3
Particle protective performance
Under the specified conditions, the ability of the mask to block particulate matters,
expressed as percentages.
4 Grading
The particle protective performance of masks is divided from high to low into Grade A,
Grade B, Grade C and Grade D; the ambient air quality to which each grade of masks
is applicable is as shown in Table 1. All grades of masks shall be able to reduce the
concentration of inhaled particulate matters (PM2.5) to ≤ 75 μg/m3 (the ambient air
quality index category is good or above) in the corresponding air pollution environment.
6 Test methods
6.1 Visual inspection
EXTRACT of 10 masks, INSPECT them using visual inspection method. The
inspection light is subject to normal natural light; if fluorescent lighting is used, the
illumination shall be not less than 400 lx.
6.2 Color fastness to rubbing
TEST according to the specifications of GB/T 29865. For color fastness to dry rubbing,
the outer layer of the mask is tested; for color fastness to wet rubbing, the layer of the
mask contacting with human face is tested.
6.3 Formaldehyde content
TEST according to the specifications of GB/T 2912.1.
6.4 pH value
TEST according to the specifications of GB/T 7573. The sample is cut from the layer
of the mask contacting with human face.
6.5 Decomposable carcinogenic aromatic amine dyes
TEST according to the specifications of GB/T 17592 and GB/T 23344.
NOTE. In general, test according to GB/T 17592 first, when aniline and/or 1,4-
phenylenediamine are detected, test according to GB/T 23344.
6.6 Ethylene oxide residues
According to the product identification, the mask treated with ethylene oxide is tested
according to the specifications of Clause 9 in GB/T 14233.1-2008. TAKE a parallel
sample to test, and the sample is cut from the mask body. If one of the test results is
qualified, and another test result is unqualified, the mean is not calculated; it shall
resample to test, and the highest value is taken as the test result. The calculation result
is expressed as relative content, accurate to one decimal place.
6.7 Inspiratory resistance
6.7.1 Sample and pretreatment
4 samples, of which 2 are untreated samples and the other 2 are samples pretreated
according to A.3.2 of Annex A. If the test sample has different models, each model
shall have 2 samples, of which 1 is untreated sample and the other is a sample
6.7.4 Test methods
CHECK the airtightness and working condition of the testing device. ADJUST the
ventilation capacity to (85 ± 1) L/min and SET the system resistance of the testing
device to 0.
WEAR the test sample on the matching test head model, ADJUST the wear position
and the tightness of the headband of the mask, to ensure that the mask is in close
contact with the test head model. ADJUST the ventilation capacity to (85 ± 1) L/min,
MEASURE and RECORD the inspiratory resistance. During the test, TAKE appropriate
measures to avoid attaching the sample to the respiratory tube.
6.8 Expiratory resistance
6.8.1 Sample and pretreatment
The requirements are the same as those of 6.7.1.
6.8.2 Testing device
6.8.2.1 The testing device of expiratory resistance is as shown in Figure 1.
6.8.2.2 The flowmeter is the same as that of 6.7.2.2.
6.8.2.3 The micro-pressure meter is the same as that of 6.7.2.3.
6.8.2.4 The dimension of the test head model is the same as that of 6.7.2.4.
6.8.2.5 The ventilation capacity of the air compressor shall be not less than 100 L/min.
6.8.3 Testing condition
The requirements are the same as those of 6.7.3.
6.8.4 Test method
CHECK the airtightness and working condition of the testing devic...
