INTRODUCTION

Reports 63S and 63G comprise the third set of reports

for the 79-80 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.

Notes and comments to individual laboratories and "Best

Values" applicable to a particular method are given

following Table 1 for each method. See page 1 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.

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

or the reports in general, contact 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; 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 perfor- mance level against the precision statement given in the test method or specification.

The average of the Individual laboratory MEANS, excluding laboratories flagged ( see column F) with an X. #, or . The GRAND MEAN is given in DS customary units and,

where applicable, in SI metric units.

The standard deviation of the laboratory MEANS about the GRAND MEAN; an index of the

among-laboratory precision.

The deviation or difference of the laboratory MEAN from the GRAND MEAN. The normal deviate or ratio of the DEV to the SD 0F MEANS, an indication of the de*

gree 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.

The standard deviation of repeated measurements; that is, of individual test determinations about their MEAN. The average of the individual laboratory SDR's; an index of the wlthln-laboratory

precision of repeated measurements.

The relative standard deviation of repeated measurements, tbat is, the ratio of the

SDR to the AVERAGE SDR: an indication of the ability of a participant to repeat his or her measurements relative to the average ability. The greater the number of TEST

DETESMINATIdNS the closer the S. SDR should be to unity. If R. SDR is outside the

limits given below, the participant may not be following the procedure considered

Flag, with following meaning:

Included in grand mean and inside 95% error ellipse.

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 or her testing procedure.

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

2 for explanation of Graph).

Excluded because data were not understood or because of a non-coded variation reported by the laboratory. (See the notes following Table 1 for each method).

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

Excluded because data for one sample are missing.

Included in grand mean but only after omission of one or more ‘wild 1 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.

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.

Distances along major and minor axes of error ellipse. If special additive or con- current model of the measuring process applies to this method, the distance along the

REPR0D *

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 degrees. The solid

sloping line, which may or may not lie close to the 45 degree 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 that an 1 S 1 is plotted as an

•O'. A participant whose plotted point falls outside of the ellipse should carefully

reexamine the testing procedure he or she 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 re- tained in the analysis, the graph Is not plotted.

The International System of U.iils (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 unite for

the same data.

In addition to several quantities already defined above, the summary shows the following values for each test method:

The number of replicate test determinations used in this Collaborative Reference Program.

The number of replicate test determinations in a test result required by the applicable TAPTI Official Test Method or assumed here if there is no TAPPI Official Test Method. This quantity is needed in the computation of TAPPI repeatability and repro- ducibility from the SD OF MEANS and the AVERAGE SDR. See TAPPI Official Test Method T1206 for definitions and computations.

TAPPI repeatability; a measure of the withl n-laboratory precision of a test result. TAPPI reproducibility, a measure of the between-laboratory precision of a test re- sult.

16. ABSTRACT (A 200-word or teas factual 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 byproduct 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
