Abstract
A method for evaluating the sensitivity of a glazing to forming quench marks depending on its anisotropy, the sensitivity being evaluated by computing parameter σ, the quench marks resulting from different optical phase shifts in different regions of the glazing for a vision in transmission or reflection and from either side of the glazing, the method including computing a transmission parameter T, Tthrough face 1 or 2 or a reflection parameter R, Rfrom face 1 or 2, this computation being done for a region of the glazing without optical phase shift and for a region of the glazing inducing an optical phase shift δ; computing a parameter ΔE(δ) corresponding to the color difference between said regions, based on at least one of T, T, R, R, and computing σby applying a function G dependent on computed ΔE(δ) and where appropriate on the one or more corresponding δ.
