J02.1997)
Principle 3
3.1 white card like the (other equivalent substance or piece of cloth, etc.) consisting of five matte white card, corresponding to the perception of whiteness five full-stop
Whiteness grade, which means white 5,4,3,2,1.5 highest purity level, level 1 represents the lowest purity of white, middle series of white purity successively handed
Less. Whiteness is determined by the color measurement instrument, whiteness values and tolerances specified in Table 1.

Whiteness level of whiteness W10 tolerance
± 3
Tinge index (TW, 10) control range. -3 < TW, 10 < 3
3.2 whiteness (W10) and tinted index (TW, 10) is measured by using a color measurement and calculation, see GB/T 8424.2.
3.2.1 whiteness (for CIED65 illumination and 196410 ° observer) according to equation (1).
W10 = Y10 + 800 (0.3138- x0 10) +1700 (0.3310- y 10) (1)
Where.
W10 --- whiteness of the sample;
Y10 --- tristimulus value of the sample;
10 10 --- x0 and y chromaticity coordinates of the specimen;
0.3138 and 0.3310, respectively --- totally reflecting diffuser x0 and y chromaticity coordinates of 10 10.
3.2.2 tinge index (for CIED65 illumination and 196410 ° observer) according to equation (2).
TW, 10 = 900 (0.3138- x0 10) -650 (10 0.3310- y) (2)
