EN ISO 12311 Sunglasses and Similar Eye Products

Explaining the requirements and test methods for sunglasses and similar eye products, the EN ISO 12311 standard is a European standard on its basis and has been re-published by the International Standards Organization (ISO). This international standard applies to all sunglasses. If it is proved to be equivalent, other test methods can be used instead of the test methods in this standard.

The main test methods included in the EN ISO 12311 standard are:

• Test methods for the evaluation of structures and materials:
  • Structure, marking and prior evaluation of information
  • Test method for evaluating filter material and surface quality
• Test methods for measuring spectrophotometric properties
  • Spectral transmittance measurement
  • Measuring light transmittance equation
  • Calculation of ultraviolet transmittance
  • Calculation of solar blue light transmittance
  • Calculation of solar IR transmittance
  • Absolute spectral reflection measurement
  • Absolute light reflection
  • Wide angle scattering
• Test methods for measuring optical properties
  • Test method for spherical, astigmatic and prismatic refractive forces
  • Test method for prism imbalance of full sunglasses or filters covering both eyes
  • Test method for local variations in breaking strength
  • Test methods for mechanical properties
  • Test method for minimum robustness of filters
  • Test method for impact resistance of filters
  • Test method for the impact resistance of sunglasses
  • Test method for frame deformation and filter retention

The standard in question was published by the Turkish Standards Institute (TSE) in our country with the following title: TS EN ISO 12311 Personal protective equipment - Test methods for sunglasses and similar eye products.

Within the scope of protective clothing tests, TS EN ISO 12311 sunglasses and similar eye products test services are also provided to our businesses by our organization.
