Correction:
The last line should read:
C*(ab) = C*(ab,standard) OR [C*(ab,1)C*(ab,2)]^(1/2)
Does anyone have the formula for delta E 94 that I could use to plug into
Excel?
Subscripts are shown in parentheses:
∆E*(94) = [ ( ∆L* / k(L)S(L) )^2 + ( ∆C*(ab) / k(C)S(C) )^2 + ( ∆H*(ab) / k(H)S(H) )^2 ]^(1/2)
where:
S(L) = 1
S(C) = 1 + 0.045C*(ab)
S(H) = 1 + 0.015C*(ab)
k(L) = k(C) = k(H) = 1 (for reference conditions)
C*(ab) - C*(ab, standard) OR [ C*(ab,1)C*(ab,2) ]^(1/2)
Ken
