The first grade indicates optical class, 1 is best, 2 is not permitted according to newest directiive 425/2016.

The second grade indicates measurements in light state, 1 is best, 2 is not permitted according to newest directiive 425/2016, different wavelengths spectral transmittance through ADF, The more diffraction there is, the less sharp received, more visible light perceived.

The third grade indicates measurements in darkness state, 1 is best, 2 is not permitted according to newest directiive 425/2016. The test is to measure different dark shade of ADF through different wavelengths spectral transmittance. All the measurements should match.

The fourth grade indicates angle dependence of luminous transimittance, 1 is best, 2 is good. Maximum aberration is scale number for angles of incidence up to ±15°, negative aberration for angles of incidence up to ±30°. If result is 1, that means the welder can perceived unchanged dark shade no matter he looks up or down.
