3 Terms and definitions
Terms and definitions determined by GB/T 30042, as well as the following, are
applicable to this document.
5 General requirements and test methods
5.1 Biocompatibility
Eye and face protection products shall meet the requirements of the intended use and
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 lig...
