Describes techniques for conducting intra-laboratory and interlaboratory studies, analyzing the results of intra-laboratory and interlaboratory studies and the formulation of appropriate precision statements for TAPPI test methods. The techniques recommended have the primary purpose of providing reliable information on the basis of which a broadly applicable precision statement can be made regarding the performance of a TAPPI test method.
