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; i.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.)

Each 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

among-laboratory 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 nvunber 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

VAR - Code for instriament type or variation in

condition, see second table.

F - Flags 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.)

M - Excluded because data for one sample are missing

X - 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 participant should take this as a warning

to reexamine his testing procedure

S - Included in grand mean but only after

omission of one of 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.

0 - Included in grand mean and inside 95/2 error

ellipse

.

COORDINATES - 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 -

AVG R. SDR -

Graph -

Lengths of the major and minor axes of

the ellipse and the angle that the major

axis makes with the horizontal axis.

Average of the R. SDR for the two samples;

an indication of the laboratory's precision

of repeated measurements.

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% cf

the points representing the laboratories.

Plotted symbols are as explained above

(under F), except that 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.

il 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

Best values: J29 23 double folds

J31 75 double folds

The ISO (International Standards Organization) Is proposing that MIT folding endurance be reported

as the logarithm (to the base 10) of the double

fold Instead of the double fold as in the past.

Please see page 43 of this report for a demonstration of this proposal.

The ISO (International Standards Organization) is proposing that MIT folding endurance be reported as the logarithm (to the base

10) of the double fold instead of the double fold as in the past.

Analysis T30-1 in this report is the same as in the past with no

changes. This analysis, T30-2, shows the data as the ISO proposes.

This analysis used the raw data reported for T30-1. The raw data

are converted to the logarithm (base 10) as shown in the example to the right, and then the mean of the converted data is calculated

and reported as ISO folding endurance.

16. ABSTRACT (A 200-word or leas tactual summary of most 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.

17. KEY WORDS (six to twelve entries; alphabetical order; capitalize only the first letter of the first key word unless a proper nam>s separated by semicolons)

Collaborative reference program; Laboratory evaluation; Paper; Precision;

Reference samples, Testing calibration
