SafeGuardS Asian man in sunglasses

In October 2015, a draft GB standard for sunglasses and sunglare filters (part 1: requirements; part 2: test methods) was proposed and the approved standard is expected to be published in 2016.

The draft standard adopts ISO 12312-1: 2013 as a reference standard with modifications:

The main differences between the draft GB standard and the ISO standard are
1. Cancelled ISO 12312-1: 2013, clause 6.2 Local variations in refractive power
2. Modified ISO 12312-1: 2013, clause 7 (impact resistance of filter); requirements of Polarizing filters

 

Newly added requirements:

  1. Integrity (adhesion) of external coating
  2. Requirements of specification of spectral transmittance

And following are proposed mandatory requirements:

- Transmittance

  • transmittance and filter categories

  • uniformity of luminous transmittance

  • requirements for road use and driving

  • wide angle scattering

  • additional transmittance requirements for photochromic filters and polarizing filters

  • claimed transmittance properties

- Refractive power

  • spherical and astigmatic power

  • prism imbalance

- Endurance of sunglasses

- Frame deformation and retention of filters

- Resistance to solar radiation

- Resistance to Ignition

- External coating properties

  • Resistance to perspiration

  • Adhesion of external coating

- Coverage area of sunglasses

- Information and Labelling
