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. A plot of the spectrophotometric curves of the samples was provided by Hemmendinger Color

Laboratory, Belvedere, New Jersey. Reflectance values and colorimetric data for 45/0 geometry usually provided by NBS were unavailable for this report.

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

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

KEY TO TABLES

MEAN

GRAND MEAN - (GR. MEAN)

SD OF MEANS -

INST CODE -

The average of individual test determinations.

The average of the individual laboratory MEANS,

excluding laboratories flagged (see column F)

with an X, #, or +.

The standard deviation of the laboratory MEANS

about the GRAND MEAN: an index of the amonglaboratory precision.

Code for instrument type and color space used

to report meansurements , see Table of Instrument

Codes.

F - Flag, is based on AE column with the following meaning:

0 - Included in grand mean analysis.

* - Included in grand means but results are between

two and three standard deviations. The participants

should take this as a warning to reexamine testing

procedures.

X - Excluded from all calculations because AE is beyond

(3) standard deviations.

+ - Excluded from all grand mean calculations because

lab is using a nonstandard instrument or test method.

# - Excluded from all grand mean calculations because data were not understood, data were extreme, late, or insufficient information was supplied concerning instrument

and test method used.

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

to have either an 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 column.

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

than 2 but less than 3 of the appropriate stnadard 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.

aE Calculation

aE is calculated in the Color and Color Difference Collaborative

Reference Program by the FMC2* equations (X, Y, Z analysis) as follows:

The yellow-blue chromatic difference is

the lightness difference is

AL = 0.279K

(PAP + QAQ)/aD;

and the red-green chromatic difference is

AC

The quantity, D, is an abbreviation,

Notes on Specific Laboratory Results

C241 - Reported extreme a value compared to other labs

on samples D05 and D06

C256A, C256B

C637, C633 - Data received too late for inclusion in Grand

Mean Statistics

C320, C538 - Apparent reporting or measurement problem

C514, C662 - Used illuminant D-65

C549 - Apparent reporting or measurement problem on mean X samples D07 and D08

C608 - Reported extreme X and Y values compared to

other labs on samples D07 and D08

C664 - Reported extreme Y and Z values on all five

samples

Notes on Samples

Several labs reported that the sample identification mark on sample

W17 showed through in the test area. Care will be taken to insure

that this does not happen in the future.

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.

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.
