use environment, and shall not contain any factors that affect the health or safety of the
wearer.
Manufacturers shall ensure that material precipitation will not cause harm to the
wearer’s skin. Manufacturers can confirm the safety of materials by requesting material
safety test reports from material suppliers.
5.2 Structure and adjustment
Eye and face protection products shall not have protrusions, sharp edges, or other parts
that may cause discomfort or injury during use.
For structures or accessories on eye and face protection products that can be
disassembled, adjusted, and replaced, manufacturers shall ensure the convenience of
disassembly, adjustment, and replacement, and simplify the operation process as much
as possible. The operation process shall comply with ergonomic requirements. Products
shall be inspected by visual inspection, touch and other methods.
5.3 Cleaning and disinfection
The manufacturer shall provide the materials, methods and steps for cleaning,
disinfection and maintenance of eye and face protection products in the instructions for
use. After cleaning, disinfection and maintenance according to the methods provided
by the manufacturer, the performance of the eye and face protection products shall
neither change nor affect the health of the wearer. This can be confirmed through
performance testing and requesting material safety test reports from material suppliers.
6 Geometric optical performance requirements and testing
methods
6.1 Field of view
6.1.1 Eye and face protection products not applicable to road driving
For eye and face protection products that are not suitable for road driving, the horizontal
bitamporal field of view of each eye in the wearing position shall not be less than 30°,
the horizontal nasal field of view shall not be less than 30°, and the vertical field of
view shall not be less than 30° in both the upper and lower directions of the line of sight.
See Figure 6 for a schematic diagram.
7.3 Scattered light
The wide angle scattering value shall not be greater than 2%. When the visible light
transmittance of eye and face protection products is not less than 15%, the test shall be
carried out according to the method given in 7.1 of GB/T 2410-2008. When the visible
light transmittance of eye and face protection products is less than 15%, the test shall
be carried out according to the method given in 7.2 of GB/T 2410-2008.
7.4 Reflectance
For eye and face protection products coated with an anti-reflection coating, the visible
light reflectance shall be less than 2.5%. Test according to the method given in 5.3 of
GB 10810.4-2011.
7.5 Driving transmittance requirements and traffic light identification
7.5.1 Transmittance requirements
The visible light transmittance of eye and face protection products suitable for driving
shall not be less than 8%. Test according to the method given in GB/T 32166.2.
7.5.2 Traffic light identification
Its spectral transmittance at 475 nm ~ 650 nm shall not be less than 0.2τν, and the
relative visual attenuation factor Q for red, yellow, green and blue signal lights shall not
be less than 0.8. GB/T 30042 gives the calculation method of the relative visual
attenuation factor Q.
8 Physical and mechanical performance requirements and
testing methods
8.1 Protection area
8.1.1 Eye protection area
Figure 8 and Table 4 show the basic eye protection area. All eye and face protection
products applicable to this document shall be able to cover this area and ensure the
safety of the wearer. For eye and face protection products with side protection, the side
protection area in Figure 8 shall also be covered.
Figure 9 and Table 5 show the eye protection areas of eyeglasses-type protector with
high-speed particle impact protection performance. Figure 10 and Table 6 show the eye
protection areas of eye shield-type protector with high-speed particle impact protection
performance.
9.3 Marking arrangement methods and requirements
The markings of eye and face protection products consist of basic marking, size
marking, driving and traffic light identification marking, and high-speed particle impact
protection performance marking. Eye and face protection products shall be marked
according to the above requirements and ordering.
The basic marking is “GB 14866”, which means that eye and face protection products
meet the basic requirements of serial number 1 in Table 10.
The size marking refers to the corresponding size of the head model for eye and face
protection products in Appendix A of eye and face protection products, that is, small,
medium, and large, which shall be marked according to serial number 2 in Table 10.
The driving and traffic light identification marking shall be marked in accordance with
the requirements of serial number 3 in Table 10.
The high-speed particle impact protection performance marking shall be marked
according to serial number 4 in Table 10.
Example 1: GB 14866 S, this marking indicates that the eye and face protection product
meets the basic requirements of serial number 1 in Table 10 and the size is small.
Example 2: GB 14866 M Driving, this marking indicates that the eye and face
protection product meets the basic requirements of serial number 1 in Table 10, the size
is medium, and it is suitable for driving.
Example 3: GB 14866 L+, this marking indicates that the eye and face protection
product meets the basic requirements of serial number 1 in Table 10, the size is large,
and it has high-speed particle impact protection performance.

Appendix B
(Normative)
Visual field measurement methods
B.1 Measuring devices
B.1.1 Goniometer, the uncertainty of which shall not be greater than 1°.
B.1.2 Head model, which shall comply with the provisions of Appendix A.
B.1.3 Continuous laser, where the beam diameter is 2 mm ± 1 mm.
B.1.4 Photoelectric detector, which is placed at the vertex of the cornea of the head
model. The positions of the photoelectric detector and the continuous laser can be
interchanged.
B.2 Measurement steps
B.2.1 According to the instructions, put the sample on the head model and put it in the
wearing position.
B.2.2 Set the goniometer to 0 ° and adjust the continuous laser so that the beam can
vertically illuminate the photodetector at the corneal vertex of the right eye of the head
model. The angle when the head model is rotated toward the nasal direction around the
vertical rotation axis passing through the corneal vertex until the edge of the lens or the
frame blocks half of the beam is the horizontal bitamporal visual field.
B.2.3 Repeat the above steps to rotate the head model toward the bitamporal side and
measure the horizontal nasal visual field.
B.2.4 Set the measuring instrument to 0 ° and adjust the continuous laser so that the
light beam can vertically illuminate the photoelectric detector at the corneal vertex of
the right eye of the head model. Rotate the head model up and down around the
horizontal rotation axis passing through the line connecting the corneal vertices of the
two eyes. The angle when the edge of the lens or the frame blocks half of the light beam
is the vertical upper and lower visual field.
B.2.5 For products that cover both eyes, the horizontal bitamporal visual field of the
right eye shall be measured on the right eye, and the horizontal bitamporal visual field
of the left eye shall be measured on the left eye.
