GB 32166.1-2016Personal protective equipment - Eye and face protection - Occupational eye and face protectors - Part 1: Requirements (English PDF)

4.1 Functional types of occupational eye and face protectors

The function of occupational eye and face protector refers to the ability to

protect against one or more of the following dangers.

4.2 Types of occupational eye and face protectors

According to the structure and style, occupational eye and face protector can

be divided into the following types.

5.1 Harmless

Occupational eye and face protectors in contact with the skin shall meet the

requirements of the purpose of use and the environment of use. There shall be

no factors that endanger the user's health or safety.

5.2 Headband

The headband shall be adjustable or self-adjusting.

Without external force, the width of the contact between the headband that

plays the main role in fixing the head and the face of the wearer shall not be

less than 5 mm.

5.3 Minimum size requirements for assembled lenses

The minimum size of the assembled lens shall meet the requirements of Table

1.

5.4 Optical requirements

5.4.1 Spherical, cylindrical, prismatic degrees

5.4.2 Visible light transmittance

Test according to the method specified in 5.3 of GB/T 32166.2-2015.For

colorless lenses, the visible light transmittance at the reference point shall not

be less than 85%.

5.4.3 Scattered light

5.4.3.1 Wide-angle scattering (haze)

When the visible light transmittance of the occupational eye and face protector

is greater than or equal to 15%, the test is performed according to the method

specified in 5.4 of GB/T 32166.2-2015.

5.5 Strength

5.5.1 Minimum strength of unassembled lens

Perform the test according to the method specified in 6.1.1 of GB/T 32166.2-

5.5.2 Minimum strength for occupational eye and face protector

Perform the test according to the method specified in 6.1.2 of GB/T 32166.2-

5.6 Anti-aging performance

5.6.1 Thermal resistance

The test shall be performed in accordance with the method specified in 6.2 of

GB/T 32166.2-2015.The sample after the test shall not be deformed, peeled or

damaged.

5.8 Packaging and marking

5.8.1 Packaging

Products shall be properly packaged and must be accompanied by a product

certificate and instruction manual.

5.8.2 Marking

Provide the following information in one or any combination of occupational eye

and face protector, labels, product's minimal packaging, instruction manuals.

6.1 Requirements for optical radiation protection

6.1.1 Specific requirements for different types of filters

6.1.1.1 UV attenuation filter

The specific requirements for UV attenuation filters are as follows. UV

attenuation filters that cannot meet the requirements of scattered light are

identified by the code U; the others are identified by the code UC.

6.1.1.2 IR attenuation filter

The specific requirements of the infrared attenuation filter are as follows. The

infrared attenuation filter that cannot meet the selectivity requirements for color

recognition in item b) is identified by the code I, whilst those that meet the

requirements are identified by the code IC.

6.1.1.3 Anti-glare filter

6.1.1.3.1 Transmittance requirements

The transmittance of the anti-glare filter shall meet the requirements of Table 8.

6.2 Additional requirements for eye and face protectors for

non-radiation industries

6.2.1 Protection from high-speed particle impact

Occupational eye and face protection against high-speed particle impact must

have side protection.

6.2.2 Anti-impact performance of heavy objects

This clause applies to the protective performance of occupational eye and face

protector against large-mass impact from high places. It is tested in accordance

with the method specified in 6.7 of GB/T 32166.2-2015.

6.2.3 Droplet protection (only applicable to goggle-type protector)

Test in accordance with the method specified in 6.8 of GB/T 32166.2-2015.

Occupational eye and face protector with droplet protection shall meet the

following requirements.

6.2.4 Anti-fogging of lens

Test the sample in accordance with the method specified in 6.10 of GB/T

32166.2-2015.The sample shall not be fogged for at least 8 s.

Types of light radiation and determination of shading number

A.1 Types of optical radiation

Occupational eye and face protector (excluding laser eye protector and welding

protector) can be used to protect the radiation from natural light or artificial light

sources, such as sunlight which has a wavelength in the ultraviolet spectrum

range, visible spectrum range and infrared spectrum range.

Ultraviolet spectrum is usually divided into 3 parts, long-wave ultraviolet (UV-A)

is 380 nm ~ 315 nm, medium-wave ultraviolet (UV-B) is 315 nm ~ 280 nm, far

ultraviolet (FUV) is 280 nm ~ 180 nm. FUV is part of short-wave ultraviolet (UV-

C) with a wavelength of 100 nm ~ 280 nm. Because air has a strong absorption

of light radiation with a wavelength range of less than 180 nm, professional eye

protectors no longer consider this wavelength band.
