INTRODUCTION

This Collaborative Reference Program is sponsored by the Manufacturers

Council on Color and Appearance and the National Bureau of Standards.

Four times per year, color chip samples are distributed to each participating laboratory. After the data has been returned to and

analyzed by NBS, a report (as illustrated by this report) showing

the data from all participants is prepared.

Reflectance values for 40 wavelengths and colorimetric data for 45/0

reflectance factor have been provided by NBS. For further explanation,

see page vi. A plot of the spectrophotometric curves of the samples

was provided by Hemmendinger Color Laboratory, Belvedere, New Jersey.

The NBS Reflectance values have succeeded the tentative values which

were given in previous reports.

If there are any questions on the notes, the analyses, or the report

in general, contact J. Horlick on 301-921-2946.

EXPLANATION OF DATA FOR WHITE SAMPLE

Specimens of a white sample were distributed to the participants along

with the usual two pairs of colored specimens, and each participant was asked to return measurement data for the white specimen, reporting re- sults in the same manner as for the colored specimens.

As a first step, three laboratories were selected to serve as "reference"

laboratories for the purposes of this analysis and the average of their

X, Y, Z values for the white sample were computed. Next, the ratios of

the participants data to the combined reference laboratory values were

calculated for each participant (transformed to X, Y, Z space if necessary).

These ratios are shown in the White Sample Analysis tables.

Two observations can be made about the data in the White Sample Analysis

tables. First, the participants as a whole tend to be high compared with the

combined average values obtained by the selected reference laboratories.

Second, a few participants had noticeably extreme values for one or more

of the components and these participants especially should look to the cause.

Next, the ratios in the White Sample Analysis tables were used to "adjust"

the data of the normal data tables to obtain the adjusted data table values.

The adjustment consisted of dividing the X, Y, Z values of the normal data

tables by the respective ratios in the White Sample Analysis tables.

The significant change in the adjusted data tables is in the SD OF MEANS.

Comparison of these among-laboratory standard deviations with those in

the normal data tables, shows considerable reduction for X, Y, Z. Thus

part, at least, of the disagreement among participants is due to errors in

standardization that could be corrected through use of an agreed-upon white

standard. There is no similar significant change for AX, aY, and AZ.
aE Calculation

aE is calculated in the Color and Color Difference Collaborative

Reference Program by the FMC2* equations as follows:

The yellow-blue chromatic difference is

AC

] = K^PaP + QAQ)/bD 2

- K

] AS/b;

the lightness difference is

AL = 0.279K

2 (PaP + QAQ)/aD;

and the red-green chromatic difference is

AC

3 = K-j (QaP - PAQ)/aD.

The quantity, D, is an abbreviation,

D = (P

NOTES ON NBS REFLECTANCE VALUES

The tables on page 17 of this report contain absolute reflectance

values measured at 40 wavelengths (38G-770 nm) and tristimulus

values for three of the five samples covered by this report.

The measurements were performed by the Radiometric Physics Division

of the National Bureau of Standards.

These values represent state-of-the-art color measurements on a single specimen of each sample. Thus the results give an accurate

picture of the values for single specimens and are not an accurate

measure of the whole sample population. Participants should be aware of this concept when comparing their measurements to these

NBS values.
KEY TO TABLES

MEAN The average of individual test determinations.

GRAND MEAN - (GR. MEAN)

0 -

The average of the individual laboratory MEANS,

excluding laboratories flagged (see column F)

with an X, # s or +.

The standard deviation of the laboratory MEANS

about the GRAND MEAN: an index of the among1 aborato ry precision.

Code for instrument type and color space used

to report measurements, see first table.

Flag, is based on aE Column with following meaning:

Excluded because data were not understood; because

of a non-coded variation reported by the laboratory

or data received late.

Excluded because data for one sample are missing

Excluded from all calculations because AE is beyond

(3) standard deviation units.

Included in grand means but results are between

two and three standard deviation units. The

participant should take this as a warning to

reexamine his testing procedure.

Included in grand mean analysis.

Note: In addition to flag (F) based on delta E column it is also possible

to have either a X or an * on individual MEANS as follows:

X - following a MEAN signifies that the mean is greater than 3 SD of

MEANS from the GRAND MEAN. The values for this laboratory have

been omitted in the calculations involving the MEAN for the

col umn.

* - following any of the MEANS signifies that that quantity is greater

than 2 but less than 3 of the appropriate standard deviations from

the corresponding average. The participant should take this as a warning to reexamine his testing procedures.

AE - Total color difference between two samples. In X, Y, Z analysis it is

calculated in MacAdams (FMC II) units. For L, a, b analysis it is

calculated in Hunter units.

literature survey, mention it here.)

Collaborative Reference Programs provide participating laboratories with the means for checking periodically the level and uniformity of their testing in

comparison with that of other participating laboratories. An important

by-product of the programs is the provision of realistic pictures of the state

of the testing art. This is one of the periodic reports showing averages

for each participant, within and between laboratory variability, and other

information for participants and standards committees.

17. KEY WORDS (six to twelve entries; alphabetical order; capitalize only the first letter of the first key word unless a proper name;

separated by semicolons)

Collaborative reference program; Color; Laboratory evaluation; Precision;

Reference samples: Testing calibration
