A-14 Measurement Values
Strength
% Strength SUM
% Strength SUM, also known as Relative Average Strength, is calculated as follows:
100.0 x
SUM Value Color
SUM Value Color
= SUM Strength %
STD
SAM
Color Value SUM is defined in the “Indices” section of this appendix. % Strength WSUM is preferred
over % Strength SUM for measurements made in reflectance.
% Strength SWL
% Strength SWL (single wavelength) is the % Strength measured at the wavelength of maximum
absorbance. This is the same % Strength described in the “Spectral Data Types” section of this
appendix, but at the appropriate single wavelength.
% Strength WSUM
% Strength WSUM, also known as Relative Weighted Strength, is calculated as follows:
100.0 x
WSUM Value Color
WSUM Value Color
= SUM Strength W %
STD
SAM
Color Value WSUM is defined in the “Indices” section of this appendix. % Strength SUM is preferred
over % Strength WSUM for measurements made in transmission.
