INTRODUCTION

This Collaborative Reference Program is sponsored jointly by the

Manufacturers Council on Color and Appearance and the National

Bureau of Standards. Four times per year, gloss chip samples are distributed to each participating laboratory. After the data has

been returned to and analyzed by NBS, two reports are sent to each

participant. The first, the "preliminary1

' report, is an individualized report comparing a laboratory’s results with the mean of all

the results received by the data due date. The second, the "final"

report, is a longer report (as illustrated by this report) showing

the data from all participants.

A key to the tables and graphs is given on the following pages.

Please make special note of the explanation of the "best values"

given on page 2 of this report.

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

reports in general, contact Jeffrey Horlick on (301) 921-2946.

Graph -

The average of individual TEST DETERMINATIONS. The

number of TEST DETERMINATIONS in the mean is given

in the upper right corner of the first table (TEST D.)

and again at the bottom of this table.

The average of the individual laboratory MEANS, excluding

laboratories flagged (see column F) with an X or //

.

The DEViation of difference of the laboratory MEAN from

the GRAND MEAN.

The Normal DEViate or ratio of the DEV to the SD of MEANS;

an indication of the degree of divergence of the

laboratory MEAN from the GRAND MEAN,

Code for instrument type or variation in condition, see second table.

Flag, with following meaning:

Included in grand mean and inside 95% error ellipse

- Included in grand means but plotted point would fall

outside of the 95% error ellipse.

- Excluded because plotted point would fall outside of the

99% error ellipse, (see below for explanation of Graph)

.

- Excluded because data were not understood, late or because analysis indicates extreme performance values or noncompliance with required test procedures.

For each laboratory the MEAN for the second sample is

plotted against the MEAN for the first sample, with each

point representing a laboratory. The horizontal and

vertical lines are the GRAND MEANS. The dashed line is

drawn at 45°. The solid sloping line, which may or may

not lie close to the 45° line, is along the major axis

of the error ellipse. The ellipse is drawn so that, on the average, it will include 95% of the points representing

the laboratories.

The rectangular area represents the + 5 percent of magnitude

of reading which is the ASTM precision statement for

reproducibility for 60° gloss.

1
Plotted symbols are as explained above (under F) . A

participant whose plotted point falls outside of the

ellipse or the rectangular area should carefully re- examine the testing procedure he is following.

Note: Graphs are plotted with an ellipse when there

are 20 or more instruments in the analysis. When

there are 10 through 19 instruments in the analysis,

the graph will be plotted but ellipses will be omitted.

When there are fewer than 10 instruments retained in

the analysis, the graph will not be plotted.

Best values - Given at the end of Table 1 for 60° gloss. These values

are based on the results obtained by the National Bureau

of Standards and the National Research Council of Canada.

All participants using equipment that is standard for the

analysis should be able to achieve results within the

plus-minus (+) limits, which are shown along with the

best values.

16. ABSTRACT (A 200-word or leas factual summary of moat significant information. If document includes a significant bibliography or

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.
