    Standard Testing Methods (Archival)

    Please note that PAPTAC Standard Testing Methods and Useful Methods are archival documents available for reference only as of October 1st, 2015

    The Pulp and Paper Technical Association of Canada Standard Testing Methods are procedures to measure the properties of pulp and paper products and of materials associated with the manufacture of these products.

    These methods are reviewed, edited for publication and adopted by the Standard Methods Committee, although they may originate in any PAPTAC technical community or any other reliable source.

    Each method is designated by:

    1. A letter, indicating the category of the test;
    2. A number, indicating the sequence in the category;
    3. A letter, indicating the class of the test (except Approved and Recommended Methods) as follows :

    P – Proposed;
    H – Historical;
    U – Useful.


    Classification of Methods

    Five classes are recognized:
    Approved Methods : To be classified as an Approved Method, a test procedure must meet the following requirements

    a. It must have been thoroughly studied, be known to yield precise and accurate data, with low lab-to-lab differences, and be sufficiently sensitive to detect differences between samples;
    b. It must be either independent of the apparatus or be performed on an apparatus which is completely specified;
    c. It must be in wide use and be recognized by a large segment of the industry.

    These methods are approved by the Executive Council of the Pulp and Paper Technical Association of Canada on the recommendation of the Standard Methods Committee.

    1. Recommended Methods: These methods are considered to be reliable and reproducible and are recommended as being the best available for measuring the properties in question.
    2. Proposed Methods: These methods are of interest to the industry but do not possess the qualifications of an Approved or Recommended Method. Although they lack the detailed study or wide application of Approved or Recommended Methods, there is an expectation that they will attain the required rigour through use.
    3. Historical Methods: These methods have been superseded by methods employing updated methodology or equipment. A sufficient body of literature has accumulated to justify their continued publication.
    4. Useful Methods: These methods, because of their simplicity and rapidity, could be used as routine mill control methods. They lack the precision and applicability of the other methods and the expectation of achieving these, and are therefore not Standard Testing Methods.

    USEFUL METHODS

    Since the Pulp and Paper Technical Association of Canada has become an independent organization from CPPA on October 19, 1998, the Technical Section, CPPA Useful Methods have been renamed PAPTAC Useful Methods.

    The PAPTAC Useful Methods are methods which, because of their simplicity and rapidity, could be used as routine mill control methods. They lack, however, the precision and the applicability of standard methods, and are therefore not Standard Testing Methods.

    Some of the more commonly used Useful Methods have been translated to French by the Physical and Chemical Standards Francization Committee.

    If you do not find a Useful Method suitable to your needs, remember to check our list of Standard Testing Methods.
