Are there any international standards for safety glasses?

Yes, there are several international standards for safety glasses. The main ones are as follows:

ANSI Z87.1

• Issuing Organization1: Developed by the American National Standards Institute (ANSI), one of the leading drivers for both U.S. and international safety standards.

• Coverage1: Applies to personal protective equipment (PPE) products such as safety glasses, face shields, and welding helmets.

• Specific Requirements4: Mandates specific performance criteria such as impact resistance, optical clarity, and coverage, ensuring protection against common hazards like impact, non - ionizing radiation, and liquid splashes. The 2020 update introduced specific criteria and markings for relaxed optics, anti - fog performance, refined transmittance allowances, and broadened the array of welding filter shades.

  
  

EN 166

• Issuing Organization: It is a European standard.

• Coverage3: Describes all personal eye - protection requirements in general. Safety glasses in accordance with DIN EN 166 consist of a frame and lenses, which are classified into safety lenses and lenses with a filter effect.

• Specific Requirements3: Technical information on safety eyewear lenses is given in a specific order, including protection class, manufacturer mark, optical class, certification mark, symbol for mechanical strength, and symbol for non - adherence of molten metal. There are also markings for different protection levels against various hazards, such as liquids, dust particles, gases, and vapors.

Australian/New Zealand Standard

AS/NZS 1337.1:20101

• Scope: It is applicable to non - prescription occupational eye - protection equipment, covering scenarios such as anti - impact, anti - dust, and anti - splash.

• Core Requirements: The impact levels are low (13m/s), medium (45m/s), high (120m/s), and ultra - high (190m/s), and the test method is similar to that of EN 166. The transmittance and scattered light of the lens should meet the requirements of visual clarity. The frame should be labeled with the protection type (such as C: anti - splash; D: anti - dust), and the lens should be labeled with the impact level and type.
