INTRODUCTION

Reports 53S and 53G comprise the fifth set of reports for the

77-78 program year. Participants in tests which involve strength

properties of paper will receive only the S report; those in

tests which measure other properties will receive only the G

report

.

Please note that some changes have been made in the computergenerated plots. These changes should aid participants in

familiarizing themselves with the International System of

Units (SI) as it applies to TAPPI test methods. Wherever

possible. Grand Means in SI units have been added at the top

of the plots, and scales in SI units have been added to the

axes allowing the reader to compare means and variability

in common units and SI units for the same data. On all plots,

sample codes and unit of test have been shifted to new positions.

Notes and comments for individual laboratories and "Best Values"

applicable to a particular method are given following Table 1

for each method. See page 4 of this report for an explanation

of "Best Values." Please do not confuse these best values with

provisional values included with the samples to detect serious

discrepancies at the time of test. NBS results, identified as L502 in the optical tests are included in some of the tables.

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

reports in general, contact Edwin B. Randall, Robert G. Powell,

or Jeffrey Horlick on 301/921-2946.

TAPPI-NBS COLLABORATIVE REFERENCE PROGRAM

BACKGROUND AND PURPOSE

In 1969, the National Bureau of Standards and the Technical Association of the Pulp and

Paper Industry established a collaborative reference program to provide a participating

laboratory with a means to check periodically the level and uniformity of its testing in

comparison with that of other laboratories.

The Interchange of paper and board products and of the raw materials for these products

requires agreement among raw material suppliers, paper and board producers, converters,

distributors, retailers, commercial testing laboratories, user organizations and the

ultimate consumer as to the meaning of test results, an agreement that cannot be achieved

without accurate and precise testing. This program is designed to help assure agreement.

HOW THE PROGRAM WORKS

Participants Select the Tests in which they wish to participate. This choice is made on

joining the program, but additional tests may be added at any time. Also new participants

may enter the program at any time.

Test Samples are Distributed Bimonthly; l.e. every 2 months.

Provisional Values are Provided with the Samples for one or both of the test levels, depending on method. The provisional values permit serious discrepancies to be detected without

delay. (It is left to the discretion of the laboratory supervisor as to whether these

values should be known to the operator.)

Bach Participant Tests the Samples , following instructions provided for each test method.

The full check on a single Instrument should normally take no more than 30 minutes. The

test results are then sent to NBS for analysis. The participant is also asked to report

other information relevant to an accurate analysis, such as test conditions and the instruments used.

Industry Means, Best Values and Other Statistics are developed from the data by NBS. The

best values are estimates based on a careful examination of all data, both current and past,

with special attention to results obtained by the National Bureau of Standards and other

recognized reference laboratories in this and other countries.

A Quick Report is Prepared for each participating laboratory reporting data on time. This

report shows the Industry mean values, and the deviations of the laboratory's results from

these values for each test method.

A Longer Summary Report, Showing the Data from all Participants, is also prepared. In

the summary report, of which this report is an example, each laboratory is identified by

a code number so that the information is maintained on a confidential basis. However,

Instruments are identified by type so participants can compare their results with

those obtained on similar instruments of different manufacture. This report includes

test averages, best values and standard deviations for individual participants and for

the group as a whole. A participant should be able to readily determine the level and

variability of his results in comparison with those of the other laboratories.

Repeatability and Reproducibility Statements such as Contained in ASTM, TAPPI and ISO

Standards are Included at the end of the report. Participants can check their performance level against the precision statement given in the test method or specification.

KEY TO TABLES AND GRAPHS

MEAN - 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.

GRAND MEAN -

(GR. MEAN)

The average of the individual laboratory MEANS,

excluding laboratories flagged (see column F)

with an X, //, or +. The GRAND MEAN is given

in US customary units and, where applicable, in

SI metric units.

SD OF MEANS - (SD MEANS)

The standard deviation of the laboratory MEANS

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

DEV - The deviation or difference of the laboratory

MEAN from the GRAND MEAN.

N. DEV - 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. A N. DEV of more than 2 or less

than -2 may indicate that the participant is

not following the procedure considered standard

for this analysis.

SDR - The standard deviation of repeated measurements;

that is, of individual test determinations about

their MEAN.

AVERAGE SDR - The average of the individual laboratory SDR’s; an index of the within- laboratory precision of

repeated measurements.

R. SDR - The relative standard deviation of repeated

measurements; that is, the ratio of the SDR to

the AVERAGE SDR; an indication of the ability

of a participant to repeat his measurements

relative to the average ability. The greater

the number of TEST DETERMINATIONS the closer

the R. SDR should be to unity. If R. SDR is

outside the limits given below, the participant

may not be following the procedure considered

standard for this analysis:

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

Flag, with following meaning:

Excluded from grand means because VAR non- standard for this analysis.

Excluded because data were not understood or because of a non-coded variation reported by

the laboratory. (See NOTES following Table 1

for each method)

Excluded because data for one sample are missing

Excluded because plotted point would fall outside of the 99% error ellipse, (see below for

explanation of Graph)

Included in grand means but plotted point falls

outside of the 95% error ellipse. The participants should take this as a warning to reexamine

his testing procedure.

Included in grand mean but only after omission

of one or more ’wild’ values; that is, test

determinations more than 3 times AVERAGE SDR

from the laboratory's MEAN. Not more than 20%

of the test determination may be excluded in

this manner without rejecting the laboratory.

Included in grand mean and inside 95% error

ellipse.

Distances along major and minor axes of error

ellipse. If special additive or concurrent

model of the measuring process applies to this

method, the distance along the minor axis

represents the random error within a laboratory

while that along the major axis also includes

a systematic laboratory component of error.

2
95% ELLIPSE - Lengths of the major and minor axes of the

ellipse and the angle that the major axis

makes with the horizontal axis.

AVG R. SDR - Average of the R. SDR for the two samples;

an indication of the laboratory’s precision

of repeated measurements.

Graph - 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.

Plotted symbols are as explained above (under

F) , except tiiat an 'S' is plotted as an 'O'.

A participant whose plotted point falls outside of the ellipse should carefully reexamine

the testing procedure he is following.

The graph is plotted with an ellipse when there

are 20 or more laboratories in the analysis.

When there are 10 through 19 laboratories in

the analysis the graph is plotted but the ellipse

is omitted. When there are fewer than 10 laboratories retained in the analysis the graph is not

plotted

The International System of Units (SI) is used on

the plots wherever possible to aid participants

in familiarizing themselves with SI. Grand means

in SI units are given at the top of the plot, and

supplementary scales in SI units are drawn along

the axes allowing the reader to compare means and

variability in common units and SI units for the

same data.

Summary -

(At end of

report)

In addition to several quantities already defined

above^the summary shows the following values for

each test method;

REPL CRP - The number of replicate test determinations used

in this Collaborative Reference Program.

REPL TAPPI - The number of replicate test determinations in a test result required by the applicable TAPPI

Standard or assumed here if there is no TAPPI

Standard. This quantity is needed in the computation of TAPPI repeatability and reproducibility

from the SD OF MEANS and the AVER SDR. See TAPPI

Standard T1206 for definitions and computations.

REPEAT - TAPPI repeatability, a measure of the withinlaboratory precision of a test result.

REPROD - TAPPI reproducibility, a measure of the betweenlaboratory precision of a test result.

Best values - Given at the end of Table 1 for each method

for which sufficient information is available.

These best values are estimates based on a careful examination of all data, both current

and past, with special attention to results

obtained by the National Bureau of Standards

and other recognized reference laboratories

in this and other countries. All participants

using equipment that is standard for the

analysis should be able to achieve results

within the plus-minus (+) limits, when these

are shown along with the best values.

16. ABSTRACT (A 200-word or less factual summary of most si^ifleant 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.

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; Laboratory evaluation; Paper; Precision;

Reference samples. Testing calibration
