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, TAPP I 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.
